GJK-CBF: Control Barrier Functions for Convex Rigid Body Collision Avoidance on SE(3)

Yi-Hsuan Chen, Shuo Liu, Wei Xiao وآخرون · 2026

Collision avoidance among convex bodies is a fundamental problem in robotics. Control Barrier Functions (CBFs) provide a practical framework for real-time safety filtering due to their computational efficiency. For general convex bodies, exact separation measures, such as distance or scaling factor, are typically compu …

Model Predictive Control for Safety-Critical Systems Using Taylor's Theorem with Lagrange Remainder

Shuo Liu, Liang Wu, Wei Xiao وآخرون · 2026

Safety-critical Model Predictive Control (MPC) formulations based on Control Barrier Functions (CBFs) often require multiple tuning parameters and may become conservative or difficult to keep feasible, particularly for high-relative-degree constraints. To address these limitations, in this paper we draw inspiration fro …

Safety Control of a Hyper-redundant Robot via Adaptive Weighted Control Barrier Functions

Zijian Cai, Kiwan Wong, Wenci Xin وآخرون · 2026

Hyper-redundant robots are well suited for confined-space manipulation due to their high dexterity, but safe operation in cluttered environments remains challenging. In addition, their slender structures often lead to uneven load distributions and nonuniform tracking errors along the body. To address these issues, this …

DR-MPC: Fast and Feasible Dynamics-Relaxed Model-Predictive Control for Legged Locomotion

Run Wang, Alapati Tuerxun, Shuo Liu وآخرون · 2026

This paper presents dynamics-relaxed model predictive control (DR-MPC), a novel MPC formulation for legged locomotion, and a tailored interior-point method (IPM) solver. The formulation combines online optimization feasibility by construction with a contact-aware input parameterization. DR-MPC moves the dynamics equali …
