Hi All, Our second winter Robotics Seminar will be on Friday, February 25 with a talk from Nick Gravish from the University of California, San Diego, who works in the area of bioinspired locomotion. The seminar will be from 10-11am, followed by an 11-11:30 student-only Q&A session. ** This seminar will be held in person in LINC 302. ** --- A simulcast of the seminar will be available via Zoom https://oregonstate.zoom.us/j/92183247338?pwd=MENOWHgvSFVGYzNjZExDT2hWRUNxdz... --- -Ross =========== Ross L.

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 two 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 simple snake-like robots with limit-cycle gaits 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 robotics. Bio: 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.
