WebThere was also an attempt to develop a hip-pattern generator using the sinusoidal function, and a foot-pattern generator for heel-strike and toe-off motions . ... In this paper, the vertical foot trajectory of the swinging leg, as well as the vertical COM trajectory of the 3-D LIPM, are generated by the CPG for the effective compensation of the ... WebAt the highest level, a foot planner selects the best next foot position for the swinging foot to land. Given this desired location, the foot trajectory generator determines a velocity profile (trajectory) for the stepping foot to follow as it lifts off the ground, swings through the air, and touches down to the ground in the specified location.
WebTo alleviate such difficulty, we propose a novel RL-based approach that contains an evolutionary foot trajectory generator. Unlike prior methods that use a fixed trajectory generator, the generator continually optimizes the shape of the output trajectory for the given task, providing diversified motion priors to guide the policy learning. WebRMA is trained completely in simulation without using any domain knowledge like reference trajectories or predefined foot trajectory generators and is deployed on the A1 robot without any fine-tuning. We train RMA on a varied terrain generator using bioenergetics-inspired rewards and deploy it on a variety of difficult terrains including rocky ...
