Abstract: |
During dynamic walking of biped robots, the underactuated rotating degree of freedom (DOF) emerges between the support foot and the ground, which makes the biped model hybrid and dimension-variant.This paper addresses the asymptotic orbit stability for criterion for DVHS is also presented,
and the result is then used to study dynamic walking for a five-link
planar biped robot with feet. Time-invariant gait planning and
nonlinear control strategy for dynamic walking with flat feet is
also introduced. Simulation results indicate that an asymptotically
stable limit cycle of dynamic walking is achieved by the proposed
method. |
