A linearization pf centroidal dynamics

WebJun 1, 2024 · This new framework is built around CM dynamic model driven by Ground Reaction Forces (GRFs) parameterized with Bézier polynomials. Due to the simple form of CM dynamics, the closed-form solution of the robot’s CM can be obtained by directly integrating the Bézier polynomials of GRFs. WebGiven centroidal quantities and desired velocity of the endeffectors, we use a standard differential inverse kinemat-ics algorithm for computing the corresponding whole body motion of the robot. We use three tasks: one tracking task on the centroidal motion which additionally stabilizes the base
