An online method to learn the closed-loop dynamics under a frozen locomotion policy with consistent and unbiased dynamics estimates is proposed, and model predictive control (MPC) predicts floating-base motion accurately and enables precise loco-manipulation.

Force-controlled loco-manipulation requires a whole-body policy to coordinate locomotion and arm motion while regulating end-effector interaction forces. This is challenging under floating-base dynamics and changing support contacts, particularly when end-effector force/torque sensing is unavailable for control. This p...

Continuum manipulators provide dexterous motion in confined spaces, but structural compliance, hysteresis, and load-dependent deformation leave residual position and orientation errors that can undermine reliable contact with rigid grippers. To address this limitation, this paper presents a lightweight support-enhanced...
