Peter Wright

Keynote Speaker: Peter Wright, Independent Motorsport Consultant

Keynote Title: Half a Century in Motorsport: From Speed to Safety

Abstract: From an early interest in motorsport the 1950's, Peter Wright joined the Grand Prix team, British Racing Motors (BRM) in 1967 at the age of 21 years. In a career spanning over half a century, he has experienced the golden age of Formula 1 technical development. After 21 years with the Lotus Group, including the roles of Technical Director of Team Lotus, Managing Director of Lotus Engineering, and a Director of Group Lotus, his career spanned the eras of the aerodynamic development of racing cars, including the development of Ground Effect and Active Suspension, during which he worked with and formed a lasting friendship with Bill Milliken.

In 1994, following the death of Ayrton Senna, Wright joined the international motorsport sanctioning body, the FIA as Technical Adviser, working on motorsport regulation, motorsport safety R&D, and road car safety. In 25 years with the FIA, projects included the introduction of Accident Data Recorders, the development of HANS, flying Le Mans sports cars, High Speed Barriers, Advanced Frontal Protection (Halo),the prevention of spinal injuries in frontal impacts, and research into motorsport concussion, as well as the development of a Balance of Performance system for GT cars, and the F1 hybrid powertrain regulations. As President of the FIA Safety Commission, he was responsible for introducing numerous safety regulations, and chaired the Jules Bianchi accident investigation.

Today, nearly retired, he is responsible for the drawing up of Sporting and Technical Regulations for the recently launched eSkootr Championship.


Peter Wright was educated at the Wellington College and later Trinity College, Cambridge, where he graduated with an MA in Mechanical Sciences. In 1967, he was recruited by F1 team British Racing Motors (BRM), where he was an aerodynamicist and vehicle development engineer. In 1969, he went to work for Specialised Mouldings Ltd., which designed and manufactured racing car bodies. He designed and ran Specialised Mouldings’ quarter-scale motorsport wind tunnel.

In 1974, Wright became General Manager of Technocraft, a company owned by Colin Chapman, the founder of Lotus. He was responsible for the F1 Team Lotus wind tunnel programme which led to the development of the first ground effect car, the Lotus 78. The car was an instant success and its successor, the Lotus 79, went on to the win the 1978 Formula One World Championship. Wright later became director of Research and Development at Team Lotus and was responsible for the development of the Lotus T78, 79, 80, 81, 86, 87, 88, 91, 92 and 93 Formula One cars. In 1983, he became responsible for Active Suspension development in Lotus Engineering, and in 1987 for the development of Active Suspension on the Lotus F1 car. In 1988, he became Managing Director of Lotus Engineering, responsible for over 600 staff.

The following year, he was appointed a Director of Group Lotus and would later go back to the track as Technical Director of Team Lotus from 1991 to 1994. With a vast amount of experience in motor sport, Wright was asked to be a technical adviser for the FIA in 1995, from which he retired in 2020. He worked across a number of FIA affiliated organisations including the FIA Foundation and the FIA Institute for Motor Sport Safety. He was President of the FIA GT and Sportscar Commissions, the FIA Safety Commission, and the FIA Environmentally Sustainable Motor Sport Commission. He served as a Director of EuroNCAP, a Member of the EuroNCAP Technical Committee, a Member of the PNCAP Technical Committee and a technical adviser on EU safety, emissions, and traffic legislation.



Dr. Raju Mattikalli

Keynote Speaker: Dr. Raju Mattikalli, Boeing Research & Technology

Keynote Title: Design of Networked Systems

Abstract: Data is revolutionizing how physical systems operate. To enable data gathering and processing, computers and sensors are increasingly being built into appliances, homes, cars, airplanes and factories. Algorithmic design of such cyber-physical systems needs to address the integration of sensing, computational and communication sub-systems into the physical design. In the aerospace industry, we have unique challenges associated with the design of such networked systems arising from their scale and complexity. In this talk I will highlight some design challenges and will describe algorithmic solutions as it applies to aerospace products including airplanes, real-time avionics and perimeter defense systems.


Dr. Raju Mattikalli is a Technical Fellow in Applied Mathematics, Boeing Research & Technology. Mattikalli has over 33 years of experience conducting R&D in the area of Computational Design and Manufacture Planning. His area of expertise is System Level Design, Mathematical Modeling, Optimization, Geometric Modeling, Networked Systems and Robotics.

He currently serves as an Associate Editor for ASTM Journal for Smart and Sustainable Manufacturing Systems.



The digitalization of enterprises and creation of model-based enterprises has become a priority among industry and government leaders. In the broadest sense, a model-based enterprise refers to creating a fully digital “system-of-systems” model that serves as the authoritative information source for all activities, organizations, and assets across an enterprise. Digital engineering is a core functional component of such a digital enterprise.

While the concept of a digital enterprise and digital engineering attracts attention with the vision of real-time information transparency, both the investment and risk of failure is high. Organizations understand the value of having relevant product data at their fingertips when making high level decisions but have struggled in implementing solutions across all levels of an enterprise. However, at separate levels, designers and engineers have achieved great successes through the adoption of digital technologies such as CAD, CAM, CAE, and technical data management software.

Aided by emerging technologies such as internet-of-things, 3D printing, augmented reality, virtual reality, digital twins, and artificial intelligence, one would expect that the benefits of digitalization are scalable across levels of digital enterprises. Towards a more holistic organizational adoption of digitalization technologies, key questions remain about the costs, risks, appropriate focus, appropriate scale, change management, how to get started, return-on-investment, and time required to recoup the investment and gain benefit. Indeed, even the metrics to measure benefits are topics to explore.

In this panel we will hear from industry experts in the oil and gas, aerospace, and automotive industries about how digitalization and model-based enterprise has been implemented in their organizations. We will hear about the strategies that have been most successful in implementing these technologies, and where they still find challenges remain. Industry participants will gain insight on how to make the business case for digital engineering, mitigating the risks of such initiatives, and how to get started. Academic attendees will gain insight into topical areas for research and teaching.

Generative Design: Succeed or Fail in Product Development

Abstract: Generative design is a computational approach for synthesizing complex geometric forms of products at different scales using techniques including evolutionary algorithms, rule-based design, knowledge-based engineering, machine learning, etc. This design methodology is attractive because it can explore innumerable possible permutations of a solution to find the best option. The diversity of designs is high, which can even result in a new design that people may have not seen or thought of before. However, having too many options could also be a bad thing, especially if you have the fear of making decisions. In addition, generative design may require the designers to create the algorithm that generates the plans and to follow the linear design process: briefing, ideation, and deciding, but these are not how designers work or how designs get done inside design firms. This panel session serves as a platform to discuss the practical issues of generative design and stimulate us to think about how to apply generative design in the future of product development.

Title: Dynamic-Based Micro and Nano Devices and Phenomena

Abstract: Miniature structures and devices have captured the attention of the scientific community for several decades for their unprecedented attractive features. Today, several micro-electro-mechanical systems MEMS devices are being used in our everyday life, ranging from accelerometers and pressure sensors in automobiles, radio-frequency (RF) switches and microphones in cell phones, and inertia sensors in video games. Due to the quest to boost sensitivity, reduce power consumption, and increase integration density, the past two decades have witnessed the emergence of Nano-electro-mechanical systems NEMS. With the increasing demand to embed more intelligence into various applications, MEMS and NEMS continue to play key role on advancing innovation.

Along with their great promise, micro and nano devices have brought new challenges and a wide spectrum of unexplained and less-understandable mechanical behaviors and phenomena. Because these devices employ moveable compliant structures and due to the interaction with short-range forces, many of these challenges are related to their dynamical behavior, which is mostly nonlinear.

In this talk, we demonstrate that by developing a proper understanding and deep insight into the dynamics and nonlinear mechanics phenomena at the micro and nano scale, new technological solutions and innovative ideas can be realized leading to new generations of superior devices. The talk will overview some of the recent revealed intriguing phenomena at the micro and nano scale including internal resonances and modes veering. Then, we discuss the realization of smart resonant sensing platforms utilizing multi-modal vibration excitation of structures to achieve multiple functionalities. These include boosting sensitivity, compensating for temperature drift, and combining sensing and actuation on a single device. In one application, active switches triggered by the detection of gas will be demonstrated. Then we discuss the static and dynamic behavior of actively tunable structures; which can be tuned using electrostatic and or/electrothermal actuation. We will discuss the potential of implementing such structures for logic, memory, and filtering applications. The talk will end on future directions andperspectives.

Title: Designing wearable robots for physical human-robot interaction

Abstract: Robots are increasingly transitioning from factories to human environments: today we use robots in healthcare, households, and social settings. I'm particularly interested in the potential for improving human performance with wearable robotic devices. Physical interactions between robots and humans offer an opportunity for the human and robot to implicitly communicate. For example, a rehabilitation robot exoskeleton can guide and train human movements, or a wearable haptic device can be used to convey informative tactile cues to the user. As engineers, we must consider the unique design and control constraints that are introduced when we design robots that are to be worn by the human, such as the complex degrees of freedom of human joints, the limitations of our human perceptual capabilities, and the necessity for compliant control algorithms to ensure user safety. This talk will feature recent research from my lab and will highlight these design challenges and the unique approaches that we have taken to ensure that the wearable robot and human achieve more together than either can achieve alone.

Title: Steps towards non-smooth multibody dynamics

Abstract: Multibody dynamics theories including non-smooth effects came up not before the second half of the last century. In my previous Institute we had quite a number of industry problems requiring urgently new solution ideas, for example gear rattling, turbine blade dampers, roller coasters and automotive drive trains, all with contact problems influencing dynamics, for some cases dominating it.

We started, as many other colleagues working in the field, with a description of such problems applying time-varying sets of equations of motion due to the fact, that contact, events like impacts or friction reduce the number of degrees of freedom of the system as long as the contact is active, and generate additional degrees of freedom when contacts are passive and open. This works for small systems, but fails for larger ones. Introducing the complementarity idea solved this problem, but generated new numerical ones. They were avoided by an idea of Alart, Curnier (1991), replacing complementarity by a set theoretical method, the prox-functions. Including these advancements into multibody system theory made successful treatment of large dynamical systems possible.

The lecture will focus on evolution of the theoretical fundament and on typical industry applications, typical also for the author’s academic life during the last decades.

Biography: After Diploma (Dipl.-Ing.) in mechanical engineering and dissertation in aerodynamics (Dr.-Ing.) at the Technical University Darmstadt, Germany, Friedrich Pfeiffer went to the German aerospace industry, today EADS, working there 8 years in the space and 8 years in the guided missile division, being involved in dynamics and control of satellites, missile systems and airbag gas generator production.

Title: On the fusion of data and models; the hybrid path to Diagnosis & Prognosis of Monitored Systems

Abstract: The monitoring of the condition of engineered systems operating under diverse dynamic loads involves the tasks of simulation (forward engineering), identification (inverse engineering) and maintenance/control actions. The efficient and successful implementation of these tasks is however non-trivial, due to the ever-changing nature of these systems, the variability in their interactive environments, and the polymorphic uncertainties involved. Structural Health Monitoring (SHM) attempts to tackle these challenges by exploiting information stemming from sensor networks.

SHM comprises a hierarchy across levels of increasing complexity aiming to i) detect damage, ii) localize and iii) quantify damage, and iv) finally offer a prognosis over the system's residual life. When considering higher levels in this hierarchy, including damage assessment and even performance prognosis, purely data-driven methods are found to be lacking. For higher-level SHM tasks, or for furnishing a virtualization of a monitored system, it is necessary to integrate the knowledge stemming from physics-based representations, relying on the underlying mechanics and dynamics principles. This talk discusses implementation of such a hybrid approach to SHM for tackling the aforementioned challenges with examples across diverse systems including civil structures and transport infrastructure, as well as wind turbine facilities.

Biography: Eleni Chatzi is currently an Associate Professor and Chair of Structural Mechanics and Monitoring at the Department of Civil, Environmental and Geomatic Engineering of ETH Zürich. She received her PhD (2010) from the Department of Civil Engineering and Engineering Mechanics at Columbia University. Her research interests include the fields of Structural Health Monitoring (SHM) and structural dynamics, nonlinear system identification, and data-driven decision support for engineered systems. She is an author of over 280 papers in peer-reviewed journals and conference proceedings, and further serves as an editor for international journals in the domains of Dynamics and SHM. She led the recently completed ERC Starting Grant WINDMIL on the topic of "Smart Monitoring, Inspection and Life-Cycle Assessment of Wind Turbines". Her work in the domain of self-aware infrastructure was recognized with the 2020 Walter L. Huber Research prize, awarded by the American Society of Civil Engineers (ASCE).

Title: Constructive Utilization of Nonlinear Dynamics in Micro-scale Systems

Abstract: During the last decades, we have witnessed that various micro systems revolutionized fundamental and applied science. Due to their small size and low damping, these devices often exhibit significant nonlinearity and thus the operational range of these impressive applications shrinks. Therefore, understanding the mechanisms leading to nonlinearity in such systems will not only eliminate obstacles to their further development but also significantly enhance their performance. Motivated by the need to advance current capabilities of various micro-systems, my research has been focused on the implementation of intentional nonlinearity in the design of micro resonators to exploit various nonlinear phenomena, not attainable in linear settings, such as broadband resonances, dynamic instabilities, nonlinear hysteresis, and passive targeted energy transfers. We developed a comprehensive analytical, numerical, and experimental methodology to consider structural nonlinearity as a main design factor enabling to tailor mechanical resonances and achieve targeted performance. Our more recent works focus on exploiting nonlinearity and multimodality simultaneously by internally coupling two or more modes through the mechanism of internal resonance. This talk will introduce various types of nonlinearity realized in micro-systems and discuss their unique behavioral features that can be exploited in the field of MEMS and AFM.

Title: Using Information Encoded in Motion to Close the loop in pHRI

Abstract: Robotics and haptics have the potential to enhance human performance and learning as well as provide unique insight into neuromotor function through sensing and quantification of human motion. At the same time, human behavior can inform the development of control strategies for complex tasks and human-robot interactions.

In physical human-robot interaction, information is communicated via motion — configurations, velocities, forces, and torques. The methods used for evaluation of motion greatly influences our ability to recognize the effects of assistance and training from a statistical standpoint, but more importantly, the mathematical structure imposed by unique measures of motion quality has significant impact on the algorithmic tools that are available to manage the interactions between robots and humans. This talk will focus on how motion measures affect the performance of the closed loop controller and our ability to statistically characterize differences in motion due to deficit, assistance, and learning.

Title: An introductory talk about the design of cam mechanisms

Abstract: Cam mechanisms have been widely implemented in modern applications, such as automatic tool changer (ATC), internal combustion engines, and pick-and-place machines. To improve the performance of these industrial applications using the cam mechanism, it is necessary to invent novel cam mechanisms that can overcome inherit disadvantages of commonly used types. Many of newly invented cam mechanisms with modified followers will be presented. Firstly, a disk cam mechanism with a translating follower that has symmetrical double rollers is found to have a better transmission angle on both the rising and the falling motions of the follower. Secondly, a positive-drive cam mechanism with dual concave faces of the follower is found to have lower contact stress over the constant-breadth and the constant-diameter cam mechanisms. At last, on the basis of an existing cam mechanism with a common roller follower, an extraneous intermediate link that has three rollers is added between the cam and the common follower. The contact forces and contact stresses of such cam mechanisms are analyzed to illustrate the advantage of spreading force transmission and reducing contact stress of this uncommon follower. In addition, the modified arrangement of the follower can be adapted to the stationary cam mechanism. Since the profiles of the stationary cam can be correspondingly determined according to desired path of the follower, the stationary cam mechanism can guide a follower with three rollers to move smoothly and free of backlash along a straight-curved stationary cam profile. Synthesis methodologies of these cam mechanisms will be shared during the Early Career Faculty Invited Presentation. Besides, it will be demonstrated that how these cam mechanisms could be a very economic and effective choice for the applications against a heavy loading or at a high speed.

Title: Considerations for Human-Robot Collaboration

Abstract: The field of robotics has evolved over the past few decades. We've seen robots progress from the automation of repetitive tasks in manufacturing to the autonomy of mobilizing in unstructured environments to the cooperation of swarm robots that are centralized or decentralized. These abilities have required advances in robotic hardware, modeling, and artificial intelligence. The next frontier is robots collaborating in complex tasks with human teammates, in environments traditionally configured for humans. While solutions to this challenge must utilize all of the advances of robotics, the human element adds a unique aspect that must be addressed. Collaborating with a human teammate means that the robot must have a contextual understanding of the task as well as all participant's roles. We will discuss what constitutes an effective teammate and how we can capture this behavior in a robotic collaborator. Biography: Monroe Kennedy III is an assistant professor in Mechanical Engineering at Stanford University. He leads the Assistive Robotics and Manipulation laboratory (, which will develop robotic assistants by focusing on combining modeling and control techniques together with machine learning tools.

Prof. Kennedy received his Ph.D. in Mechanical Engineering and Applied Mechanics and Masters in Robotics at the University of Pennsylvania, advised by Dr. Vijay Kumar, with a focus in robotics in the GRASP Lab. He was the recipient of GEM and NSF graduate fellowships.

Title: Measures of Motor Performance in Human and Robots

Abstract: The proposed talk will cover two main topics, reflecting my current and future research directions. Both topics pertain to the fundamental research question of quantifying aspects of motor performance in general mechanisms.

In the first part of the talk, I will discuss the theoretical and computational framework that is being developed for the characterization of the limits of dynamic balance in general biped systems. A systematic characterization of a threshold of balance in the state space of a given system is discussed. This threshold gives a prediction on the balancing capabilities of a given biped model, in terms of quantifiable ranges of feasible center of mass position and velocity. The characteristic shape of this balance threshold, called Boundary of Balance, can guide the design of legged mechanisms based on predefined balance requirements. This research is under experimental validation and will be translated into a technology for the quantitative assessment and training of balance performance in home-care settings.

In the second part of the talk, a model of motor task difficulty will be discussed, inspired by measures of complexity that are derived from information theory, such as Shannon’s entropy. The concept of difficulty is associated with the ability of the end-effector of a moving agent (robot or human) to accomplish a trajectory during a certain motor task. This ability depends on the fit between external (environment) and internal (agent) constraints, also known as affordance. A stochastic model of difficulty for a generalized reaching motor task is proposed as an affordance-related measure of perceived difficulty for an agent in a given task and environment. This research will prompt new perspectives in the study of movement affordance arising in the mutual interaction of humans, robots, and their environments.

The discussed research aims at providing novel benchmarks of motor behavior, which are essential for evaluating motor performance in robots, as well as in the robot-assisted workforce and in patients affected by impaired mobility.

In the long term, both topics will help steer the research paradigm on human and robot motion and control towards the new perspective of morphological intelligence, in which the complex morphology of mechanisms (e.g., large number of degrees-of-freedom, big dimension of actuation space, etc.) is not seen as an obstacle, but a source of embodied intelligence that can reduce the centralized computational demand at the higher level (e.g., brain or CPU).

Title: Design, Planning, and Control for Versatile Robotic Manipulation

Abstract: Robotic manipulation seeks to advance the way we handle objects of interest and interact with our environment using autonomous robotic systems. There are a wide range of applications such as transporting goods in warehouses, assembling parts in factories, and handling everyday objects to serve people directly, in which robots with advanced manipulation capabilities can be useful. In typical object manipulation scenarios, robots must be able to get a good hold on objects, transfer objects between secure grasps, and interact deliberately with the environment. Such tasks are still very difficult for robots today, whose versatility and dexterity are far below human levels. Achieving robotic dexterity and versatility in manipulation is thus one of the grand challenges in robotics. In this talk, I will introduce the research activities in my group on various robotic manipulation problems. Design, planning, and control techniques that will enable robots to skillfully manipulate objects and interact with the environment will be presented.

Title: Leveraging Embedded Vision Sensors to Improve Robot's Performance

Abstract: Unlike conventional industrial robots that are kept separated from humans to ensure safety, the next generation robots physically interact with humans in a shared workspace. Soft robots are made of soft materials. They are inherently safe and ideal to be deployed in a human shared environment. However, their deformation is very complex which leads to great challenges for precise perception. I address this problem with embedded vision sensors thanks to their rich visual information. The high-resolution image data is capable of dealing with the complex deformation generated by the soft robots. In addition to the robot itself, I care about the robotic manipulation skills. Soft objects are exceedingly common in our daily life such as cables, clothes, towels, and fruits. But robotic manipulation of soft objects is very challenging because soft objects are deformable. They have infinite degrees of freedom, and their modeling and control are both very difficult. I address this problem with vision-based tactile sensors, which are able to capture the complex states (locally) of the soft objects. In this talk, I will present some of my recent works in these areas. First, I will discuss the development of an exoskeleton-covered soft robotic gripper that employs embedded vision sensors providing high-resolution proprioception and tactile sensing simultaneously. Second, I will present a vision-based tactile sensor that achieves high-resolution 3D reconstruction and is favorable for robotic manipulation. Finally, I will discuss the application of the vision-based tactile sensor for a robotic cable manipulation task.

Title: Dynamical Robots via Origami-Inspired Design

Abstract: Origami-inspired engineering produces structures with high strength-to-weight ratios and simultaneously lower manufacturing complexity. This reliable, customizable, cheap fabrication and component assembly technology is ideal for robotics applications in remote, rapid deployment scenarios that require platforms to be quickly produced, reconfigured, and deployed. Unfortunately, most examples of folded robots are appropriate only for small-scale, low-load applications. In this talk, I will discuss efforts in my group to expand origami-inspired engineering to robots with the ability to withstand and exert large loads and to execute dynamic behaviors. I will show how the computational models of an origami design allow us to explore and optimize its mechanical response, and how we can leverage these designs for better performance and simpler control.

Title: Mobility and Morphing of Modular Soft Robots

Abstract: Soft materials are deemed attractive for applications where adaptability and safe interaction with the environment are imperative. Imagine a swarm of terrestrial robots that can explore an environment, and upon completion of this task, reconfigure into a spherical ball and roll out. Realizing such versatile and robust systems poses design and mobility challenges. Morphological and topology design of such soft robot modules is based in age-old geometry concepts of platonic solids. While the control challenges are addressed by adopting an environment-centric perspective where graph theory is used to construct a probabilistic model of the environment. This generic, adaptable, robust and learning-oriented framework allows us to represent complex locomotion tasks as integer linear programming optimization problems which can be easily solved using commercial, off-the-shelf solvers.

Title: Optimal Control of Multiple Powered Exoskeletons for Symmetric Human Lifting

Abstract: In this study, the optimal control of multiple powered exoskeletons for symmetric lifting motion is presented. The two-dimensional human model has 10 degrees of freedom. Four powered exoskeletons at knee, hip, spine, and elbow joints are used to aid the lifting motion. Physics-based motor dynamics are modeled with human mechanical system which is built by recursive Lagrangian dynamics. The gradient-based optimization is used to find the optimal lifting motion and controls of powered exoskeletons at multiple joints. In the optimization formulation, the design variables are the exoskeleton motor current profiles and human joint angle profiles. The inverse dynamics are used to calculate human and exoskeleton joint torques. The cost function is to minimize the sum of human joint torque squares for the lifting motion. The human and exoskeletons’ optimal joint torque profiles are reported. The optimal solution is obtained in several seconds of CPU time. The coupling of multiple powered exoskeletons at different joints for lifting is studied.
