A passive 2DOF walker: Finding gait cycles using virtual holonomic constraints
— A planar compass-like biped on a shallow slope is the simplest model of a passive walker. It is a two-degrees-offreedom impulsive mechanical system known to possess periodic so...

Modeling and control of the monopedal robot Thumper
— A hybrid controller that induces stable running gaits on a monopedal robot is developed. The robot features a rigid leg with a revolute knee and a heavy torso with center of ma...
