Smooth Computation without Input Delay: Robust Tube-Based Model Predictive Control for Robot Manipulator Planning

ICRA 2024poster

Model Predictive Control (MPC) has exhibited remarkable capabilities in optimizing objectives and meeting constraints. However, the substantial computational burden associated with solving the Optimal Control Problem (OCP) at each triggering instant introduces significant delays between state sampli…

MOMA-Force: Visual-Force Imitation for Real-World Mobile Manipulation

IROS 2023poster

In this paper, we present a novel method for mobile manipulators to perform multiple contact-rich manipulation tasks. While learning-based methods have the potential to generate actions in an end-to-end manner, they often suffer from insufficient action accuracy and robustness against noise. On the…

Simultaneous Trajectory Optimization and Force Control with Soft Contact Mechanics

IROS 2020poster

Force modulation of robotic manipulators has been extensively studied for several decades but is not yet commonly used in safety-critical applications due to a lack of accurate interaction contact modeling and weak performance guarantees - a large proportion of them concerning the modulation of inte…
