How most things run – an oscillator theory perspective on rapid locomotion

Shai RevzenAssistant ProfessorUniversity of Michigan - Department of EECS

Legged locomotion on land is often viewed in terms of "gaits" corresponding to repeated patterns of footfalls, suggesting an application of the mathematical theory of limit cycle oscillators. Unlike classical oscillators, the oscillators appearing in locomotion encounter rapid processes that are often modeled as non-smooth "hybrid" transitions.

I present an experimental scientist's perspective on rapid multilegged locomotion that lead us through the development of key tools for the empirical analysis of animal and robot gaits, and on to a discovery of new, fundamental forms of stability unique to hybrid limit cycle oscillators of multiple contact gaits.
