Singularity-Robust Prioritized Whole-Body Tracking and Interaction Control With Smooth Task Transitions

Kurzfassung

In this work, we propose a singularity-robust whole-body control framework that ensures smooth task transitions while maintaining strict priorities. The weighted generalized inverse is adopted to derive a hierarchical control law compatible with singular and redundant tasks. Moreover, a smooth activation matrix is proposed to continuously shape both null-space projectors and task level control actions. Validation has been conducted in MATLAB/Simulink and MuJoCo simulations with Rollin' Justin.
