Abstract
This paper is a study on dynamics of a two-link biped in level walking, focusing on the double support phase . For a mechanical model with generality in leg mechanism dynamics is undetermined including one degree of redundancy for planar bipeds, two for spatial ones. Unlike the common optimization-based approaches for solving such distribution problem, we consider a more simple assumption that is computationally light. Dynamics and state behavior of the resultant solution is studied on the phase plane as well as in terms of actuation and energy consumption. The effect of variations in the model and motion parameters as well as initial conditions is investigated on determinant features of gait such as the rear leg force, period of DSP, energy consumption, and step length.
