چکیده

We examine the control problem of curve-tracking for fully-actuated mechanical systems, applied to walking robots. First, we discuss earlier results on curve-tracking using a change of coordinates to split the kinetic energy in a desired and an undesired part. Then, we apply and extend these results to the case of a compass-gait biped, and show in a simulation how its robustness against surface height variations can be increased. Copyright c ©2005 IFAC

Reconstructing human push recovery reactions using a three dimensional under-actuated bipedal robot

This paper presents the ability of hybrid zero dynamics (HZD) feedback control method to reproduce human like movements for walking push recovery of an under-actuated 3D biped model. The balance recovery controller is implemented on a three-dimensional under-actuated bipedal model subjected to a push disturbance. The biped robot model is considered as a hybrid system with eight degrees of freed...

Control of a compass gait walker based on energy regulation using ankle push-off and foot placement

In this paper, we present a theoretical study on the control of a compass gait walker using energy regulation between steps. We use a return map to relate the mid-stance robot kinetic energy between steps with the two control inputs, namely, foot placement and ankle push-o↵. We show that by regulating the robot kinetic energy between steps using the two control inputs, we are able to: 1) genera...

Time-scaling Control of a Compass Type Biped Robot

This paper presents a robust control strategy driving an actuated compass gait robot towards steady and periodic gaits. By robust we mean a large basin of attraction for the limit cycle. The originality lies in the generation of the swing leg reference angle and speed as a simple function of the supporting leg angle. Simulations and experimentation with a prototype showed that the system exhibi...

Bifurcation and chaos in a simple passive bipedal gait

This paper proposes an analysis of the behavior of perhaps the simplest biped robot the compass gait model It has been shown previously that such a robot can walk down a slope inde nitely without any actua tion Passive motions of this nature are of particular interest since they may lead us to strategies for con trolling active walking machines as well as to a better understanding of human loco...

Stable locomotion control of bipedal walking robots: synchronization with neural oscillators and switching control

Two novel approaches to stable legged locomotion control (neural-oscillator based control and switching control) are studied for achieving bipedal locomotion stability. Postural stability is realized by structural dynamics shaping, and gait stability is achieved by synchronization with neural oscillators and switching control. A biologically inspired control with neural oscillators (central pat...
