Exact Signed-Distance Control Barrier Functions via Minkowski Operations for Safe Navigation among Polytopes
Yi-Hsuan Chen, Shuo Liu, Wei Xiao +2
Safely navigating polytopic environments while respecting the dynamics, control, and exact geometry of the underlying system is a challenge in robotics. Control barrier functions (…
Iterative Convex Optimization with Control Barrier Functions for Obstacle Avoidance among Polytopes
Shuo Liu, Zhe Huang, Calin A. Belta
Obstacle avoidance of polytopic obstacles by polytopic robots is a challenging problem in optimization-based control and trajectory planning. Many existing methods rely on smooth g…
Learning Safety for Obstacle Avoidance via Control Barrier Functions
Shuo Liu, Zhe Huang, Calin A. Belta
Obstacle avoidance is central to safe navigation, especially for robots with arbitrary and nonconvex geometries operating in cluttered environments. Existing Control Barrier Functi…
Control Barrier Functions via Minkowski Operations for Safe Navigation among Polytopic Sets
Yi-Hsuan Chen, Shuo Liu, Wei Xiao +2
Safely navigating around obstacles while respecting the dynamics, control, and geometry of the underlying system is a key challenge in robotics. Control Barrier Functions (CBFs) ge…
