Brief

Chris J. Paxton shares a video showing the capabilities of compliant, force-aware teleoperation for a highly constrained pick. Separately, Litian Liang presents the Universal Manipulation Exoskeleton (UME), a low-cost device with real-time haptic torque feedback meant to teach autonomous policies for force-heavy, occluded, whole-body and long-horizon mobile manipulation tasks; a blindfolded unsheathing demo is shown.

Why it matters

Chris J. Paxton highlights a demo (video) of compliant/force-aware teleoperation performing a highly constrained pick using force feedback.

Key details

  • Litian Liang’s Universal Manipulation Exoskeleton (UME) is a low-cost exoskeleton with real-time haptic torque feedback designed to train autonomous policies for force-mediated, tightly space-constrained, visually occluded, whole-body, long-horizon mobile manipulation — demo includes a teleoperator unsheathing a heavy metal sword blindfolded.
Source evidence

The kind of things you can do with compliant/force aware teleop i guess. Another cool video of a highly constrained pick.

Introducing Universal Manipulation Exoskeleton (UME)

A low-cost exoskeleton with real-time haptic torque feedback for learning autonomous policies that perform highly force-mediated, tightly space-constrained, visually occluded, whole-body, and long-horizon mobile manipulation tasks.

Using UME, the teleoperator can unsheathe a heavy metal sword completely blindfolded.
