Mid-term Spring Semester can usher in the interview season for many students seeking internship or fulltime employment opportunities. Mark Savage, Life Design Educator for Engineering Masters Students, will walk you through what to expect and how to ace the job interview. Time permitting, we may also discuss the Elevator Pitch in preparation for your upcoming Robotics Industry Day. Remember to convey some of those 800 skills that relate to some of the jobs you’ll be discussing.
Update Jan 28: Industry Day will now be virtual as we won’t know the COVID climate in the future. In order to reduce zoom fatigue, we are splitting the event into 2 half days. Industry Day will be Monday March 21 1-4pm and and Tuesday March 22 1-4pm.

Locomotion in living systems and bio-inspired robots requires the generation and control of oscillatory motion. While a common method to generate motion is through modulation of time-dependent “clock” signals, in this talk we will motivate and study an alternative method of oscillatory generation through autonomous limit-cycle systems. Limit-cycle oscillators for robotics have many desirable properties including adaptive behaviors, entrainment between oscillators, and potential simplification of motion control. I will present several examples of the generation and control of autonomous oscillatory motion in bio-inspired robotics. First, I will describe our recent work to study the dynamics of wingbeat oscillations in “asynchronous” insects and how we can build these behaviors into micro-aerial vehicles. In the second part of this talk I will describe how limit-cycle gait generation in collective robots can enable swarms to synchronize their movement through contact and without communication. More broadly in this talk I hope to motivate why we should look to autonomous dynamical systems for designing and controlling emergent locomotor behaviors in bio-inspired robotics.
Dr. Nick Gravish received his PhD from Georgia Tech where he used robots as physical models to motivate and study aspects of biological locomotion. During his post-doc Gravish worked in the microrobotics lab of Rob Wood at Harvard, where he gained expertise in designing and studying insect-scale robots. Gravish is currently an assistant professor at UC San Diego in the Mechanical and Aerospace Engineering department. His lab bridges the gap between bio-inspiration, biomechanics, and robotics, towards the development of new bio-inspired robotic technologies to improve the adaptability and resilience of mobile robots.
Designing robots for human interaction is a multifaceted challenge involving the robot’s intelligent behavior, physical form, mechanical structure, and interaction schema. Our lab develops and studies human-centered robots using a combination of methods from AI, Design, and Human-Computer Interaction. This talk focuses on three recent projects, two concerning the design of a new robot, and one that tackles designing robots that help human designers.

Prior to that he was an Assistant Professor at IDC Herzliya and co-director of the IDC Media Innovation Lab. Hoffman holds a Ph.D from MIT in the field of human-robot interaction. He heads the Human-Robot Collaboration and Companionship (HRC²) group, studying the algorithms, interaction schema, and designs enabling close interactions between people and personal robots in the workplace and at home. Among others, Hoffman developed the world’s first human-robot joint theater performance, and the first real-time improvising human-robot Jazz duet. His research papers won several top academic awards, including Best Paper awards at robotics conferences in 2004, 2006, 2008, 2010, 2013, 2015, 2018, 2019, 2020, and 2021. His TEDx talk is one of the most viewed online talks on robotics, watched more than 3 million times.
Many successful approaches to robotic locomotion and manipulation operate with high quality simulation tools. Many such approaches are “bottom-up” in a modeling sense, accounting for all internal forces and environmental interactions explicitly. These “bottom-up” models are used either beforehand (such as in reinforcement learning) and/or in real time. However, various types of robots are getting smaller, softer, and more complex (e.g. bio-hybrid actuators). Some robots lean on low-precision manufacturing and fabrication techniques, and many robots are now being asked to operate in hard-to-characterize, natural interfaces like the human body. Such attributes can render “bottom-up” simulators impractical for expected use cases on various research frontiers, such as micro-biomedical robots and soft robots deployed in uncharacterized environments. In this talk I will revisit the reconstruction equation, a result from the geometric mechanics literature that offers a “top-down” view of Lagrangian systems, permitting insights into generalizable system behaviors along a spectrum of friction-momentum dominance. I will show how these tools can permit rapid modeling of high complexity robots in their operating environment without the requirement to specify CAD models or any explicit forces. I will also discuss a related strength and weakness of the approach resulting from the use of symmetries. Surprisingly, results in simulation and hardware indicate that even with eight-jointed systems, useful behavioral models can be computed from tens of cycles of data. This suggests that high degree of freedom robots can adjust and excel in situations where explicit force models are poorly understood. I will also briefly discuss a framework for robot recovery that leans on these tools as well as a metric for a robot’s ability to cover the local space of motions, computed on the Lie algebra of the position space. The metric allows primitives to be valued for their contribution to the space of composed motions rather than just their individual qualities. Results here include a Dubins car that can learn how to turn left (with its steering wheel restricted to only turn right) in less than a second as well as a robot made of tree branches that can learn to walk around the laboratory with less than twelve minutes of experimental data. I hope to motivate the general use of structural reductions as we pursue modeling and control of the next generation of high complexity robots.
Dr. Brian Bittner received a B.S. from Carnegie Mellon and a PhD from Michigan where he researched the theory, simulation, and application of physics informed machine learning for in situ behavior modeling and optimization. He has sought out cross-disciplinary environments for research, collaborating with physicists, biologists, and mathematicians, working to facilitate insights from these fields into robotic systems. Bittner is currently a research scientist at the Applied Physics Lab. He is currently working on approaches to modeling and control for soft robots and underwater manipulation.
The talk will present a survey of my research activities, with more detailed presentation of our guidance system for robot-assisted prostate cancer surgery. The majority of prostate cancer surgery is carried out with the da Vinci surgical system. Tracking of instruments and hand-eye calibration of this robotic system enables the overlay of pre-operative magnetic resonance imaging by registration to real-time ultrasound. This enables visualization of sub-surface anatomy and cancer. We will discuss our system design, visualization and registration approaches.
We will also discuss instrumentation for force sensing using the da Vinci Research Kit, and a new approach to teleguidance for ultrasound examinations.

Flexible and soft medical robots offer capabilities beyond those of conventional rigid-link robots due to their ability to traverse confined spaces and conform to highly curved paths. They also offer potential for improved safety due to their inherent compliance. In this talk, I will present several new robot designs for various surgical applications. In particular, I will discuss our work on soft, growing robots that achieve locomotion by material extending from their tip. I will discuss limitations in miniaturizing such robots, along with methods for actively steering, sensing, and controlling them. Finally, I will discuss new sensing and human-in-the-loop control paradigms that are aimed at improving the performance of flexible surgical robots.
