ICRA 2026 | VPP-TC: A Passivity-Based Torque Safety Control Framework Based on Feasibility Theory
Researchers have developed a new framework called Viability-Preserving Passive Torque Control (VPP-TC) for robots operating in close proximity to humans. This method uses viability theory to pre-compute safe sets in an augmented state space, translating safety constraints into real-time solvable torque limitations. VPP-TC offers significant advantages over previous methods like Control Barrier Functions (CBF) by avoiding the need for second-order derivatives, resulting in higher control frequencies, smoother trajectories, and shorter paths.
