Abstract

The invention discloses an omnibearing gait switching method and system for a parallel wheel-foot robot. The method comprises the steps: establishing a kinematics model of the parallel wheel-foot robot; based on the kinematics model, taking single-leg working space constraint and walking stability constraint as consideration conditions, and stipulating a straight-going intermittent gait and a rotating gait of the parallel wheel-foot robot; and based on the straight-going intermittent gait and the rotating gait, conducting gait switching according to the walking direction and the walking posture of the parallel wheel-foot robot. In the embodiment of the invention, the motion controllability of the parallel wheel-foot robot is improved, and the overall motion stability is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of robots, in particular to a method and system for omnidirectional gait switching of a parallel wheel-foot robot. Background technique [0002] Legged robots are currently a research hotspot in the field of special robots. Legged robots with different structures and different control methods have their own advantages in terms of walking speed, load capacity, motion stability, and flexibility. However, different structural designs need to be matched with each other. The appropriate gait control algorithm to achieve optimal control performance. At present, the common serial quadruped robot has a relatively simple structure and high motion flexibility, but has a small load capacity, poor motion stability, and low energy utilization rate, and is not suitable for the needs of large loads and complex road traffic. The quadruped robot with hydraulically driven parallel wheel-foot switching has the advantages of large load,...
