Touch Helped the Robot Hold On
A combined tactile and force policy beat vision alone in a controlled grasping study.
Summary
A combined tactile and force policy beat vision alone in a controlled grasping study.
A dexterous robot study compared vision-only grasping with policies that also received fingertip tactile signals and force estimates. With demonstrations, action space and compliant control held fixed, the combined policy succeeded in 24 of 25 trials across five tabletop conditions, compared with 14 of 25 for vision alone. In three confined conditions it succeeded in all 15 trials, versus 6 of 15 for vision alone. The authors found the extra signals helped the robot reject weak contacts before lifting and regrasp when needed. The sample is small and specific to the tested setup.
