The concept of virtual holonomic constraints is extended to the case of double support, which is characterized by a closed kinematic chain and redundancy in the state variables. An...
A 3D biped with knees and a hip is naturally modeled as a nontrivial hybrid system; impacts occur when the knee strikes and when the foot impacts the ground causing a switch in the...
Abstract— This paper discusses the design principles and philosophy of the BiMASC, a biped with Mechanically Adjustable Series Compliance which incorporates tuned mechanical leg ...
