Dynamic whole-body robotic manipulation
WebAug 22, 2024 · We propose two control modes: manipulation mode and loco-manipulation mode. In the manipulation mode, we use an HQP to control the arm, legs and the base subject to the whole rigid-body dynamics of the robot. It leads to the automatic adaption of lower prioritized tasks to satisfy tasks with higher priorities.
