Controlled symmetries and passive walking
WebOur approach starts by using outputs and canonical walking functions which intrinsically capture the major characteristics of human walking behavior; this human- inspired control approach thus aims to further bridge the gap between robotics and control by using human walking data to formally design controllers (as first dis- cussed in [3]).

In previous researches, this passive gait was shown to be sensitive to ground slope and initial conditions. In this paper, we discuss the feedback stabilization of a biped robot by the “energy shaping” technique. Two designs are proposed to reduce the sensitivity of the … WebFig. 2.
