Abstract
We provide online dynamic robot task selection in human-robot collaborative contexts through a voxel-based collision avoidance system. This paper describes a partially automated screw assembly work-cell with a worker and a 6-DOF light-weight robot arm. The shared workspace is monitored by 3D point-cloud sensors. The dynamic task selection reduces robot waiting due to obstacles by exploiting situations where multiple tasks are available for the robot. Massively parallel evaluation of voxelized robot trajectories allows online avoidance of blocked paths. The robustness of the screw assembly process is increased through Cartesian compliance based on force-torque sensor feedback.
