BeingBeyond Straps Robot Hands Alongside Human Hands to Harvest Humanoid Training Data — and r/singularity Immediately Finds the Missing-Data Hole
A video of BeingBeyond's data-collection rig, which mounts robotic hands adjacent to a human operator's own hands so the robot records the same manipulation trajectories a person executes, drew 87 upvotes and 26 comments on r/singularity. The most substantive critique is a specific failure mode rather than general skepticism: a commenter points out the operator used his human hand to steady the board while pulling a plug with the robot hand, meaning the recorded demonstration is missing the stabilizing contact that made the task possible — a systematic bias toward under-recording bimanual bracing in exactly the tasks that need it. It is a concrete illustration of why hand-mounted teleoperation datasets can look clean and still fail to transfer.
