Neural Configuration-Space Barriers for Manipulation Planning and Control
Kehan Long, Ki Myung Brian Lee, Nikola Raicevic +3
Planning and control for high-dimensional robot manipulators in cluttered dynamic environments require computational efficiency and robust safety guarantees. Inspired by recent adv…
Stabilization of Nonlinear Systems through Control Barrier Functions
Pol Mestres, Kehan Long, Melvin Leok +2
This paper proposes a control design approach for stabilizing nonlinear control systems. Our key observation is that the set of points where the decrease condition of a control Lya…
Lie Group Variational Collision Integrators for a Class of Hybrid Systems
Khoa Tran, Melvin Leok
The problem of 3-dimensional, convex rigid-body collision over a plane is fully investigated; this includes bodies with sharp corners that is resolved without the need for nonsmoot…
Safe Stabilizing Control for Polygonal Robots in Dynamic Elliptical Environments
Kehan Long, Khoa Tran, Melvin Leok +1
This paper addresses the challenge of safe navigation for rigid-body mobile robots in dynamic environments. We introduce an analytic approach to compute the distance between a poly…
