Title: The price of battery degradation and the value of battery health estimation in the transition to electrified transportation

Abstract: Replacing a gasoline or diesel internal combustion engine vehicle (ICEV) with an electric vehicle (EV) will zero out the tailpipe emissions and depending on where it charges can have 50% lower green-house gas emissions. Key barrier to EV adoption is the higher up-front cost of EVs compared to ICEVs. Using transit buses, we will show how the total cost of ownership depends on the lower operating cost due to fuel and maintenance savings that depend on the route, utilization, and charging of the vehicle. If the battery stays healthy, vehicle to building, vehicle to grid, and other 2nd life applications can provide additional value streams and be considered as a long-horizon optimization problem.

The battery state of health (SOH) is thus at the crux of the payback calculations and consequently can tip the EV adoption. Unfortunately, estimating the battery health with high confidence can only be done under certain discharge patterns. Identifying the physical origin of the degradation is even more difficult but very important, because it can inform the battery management system and hence prevent further degradation. We will present various on-board signals for tracking the intrinsic “aging wrinkles” in batteries. We will conclude by highlighting the estimation of gas venting and assess the intensity of thermal runaway for first-responders and post-accident management of damaged batteries. This presentation will be similar to the one presented in IEEE ECCE and ICCAS.

Title: Robotic Fish: Make "Sense" of the Underwater World

Abstract: Bioinspired robotic fish have gained widespread interest due to their natural appeal and promising prospect for underwater sensing. In this talk I will share our robotic fish work, from lab research to field experimentation. I will focus on gliding robotic fish "GRACE", which combines maneuverability of robotic fish with energy-efficiency of underwater gliders. I will highlight the roles of dynamics and control in advancing the goal of autonomous sensing, through a series of examples motivated by applications of practical relevance: exploiting spiral dynamics of GRACE to monitor harmful algal blooms, developing distributed filtering algorithms to track movement of invasive fish species, and facilitating human-robot collaboration in underwater search and rescue.

Title: Life in the Underactuated Lane

Abstract: Underactuated mechanical systems are those with fewer actuators than degrees of freedom and arise in several applications including flexible-joint and flexible-link robots, gymnastic robots, as well as walking, flying, and swimming robots. In addition, the relatively new area of soft robots presents new challenges and opportunities for control of underactuated systems. Various tools have been applied to control underactuated systems, such as static and dynamic feedback linearization, partial feedback linearization, and passivity-based control. In this talk I will present several results that my students and I have obtained for flexible-joint robots, gymnastic robots, and other systems, and discuss how these ideas may prove useful for controlling soft robots.

Title: Haptics: A Hot Topic with Controls at its Core

Abstract: We depend on touch-based, or haptic, information throughout our daily activities, even in ways that we do not consciously realize. Given the importance of this sensory channel, haptic feedback is becoming commonplace in consumer electronic devices and advanced robotic systems. From simple smart watch vibration notifications to state of the art full body haptic displays in virtual reality games, the potential for our sense of touch to enhance information transfer and realism is clear. What is “under the hood,” making realistic haptic interactions possible? Feedback and stability are critical concepts, central to realizing high-fidelity haptics. These concepts also play out in the applications of haptic guidance, virtual environment-based training , and rehabilitation robotics that have shaped my own research. In this talk, I will discuss the fundamental concepts in dynamic systems and controls that are at the heart of these haptic interactions. I will also share how the dynamic systems and controls community launched the field of haptics, and the need for our continued engagement in the field going forward.
