A simplified forward gait control for a quadruped walking robot

Abstract

Presents a simplified forward gait for a quadruped walking robot. The proposed gait is a straight line, periodic, monotonically forward (SLPMF) gait and can easily be used for adaptive gait control, requiring only simple modifications. The authors show that given a support pattern, meaning a polygon generated by connecting the feet positions that are in contact with the ground, only certain sequences of leg movements will generate the SLPMF gait. The authors also introduce a useful method to determine how to preserve stability of a quadruped robot during the motions called for by an SLPMF gait. The authors also discuss the leg design from a hardware standpoint; the design permits independent joint control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
