Why Robot Hands Can't Wipe a Spill with a Cloth

In this episode of The Robotics Podcast, Lucas and Luna explore a deceptively simple task that still stumps most robotic systems: wiping a liquid spill with a cloth. They break down the physics of absorption, the need for real-time pressure and angle adaptation, and why even the best grippers fail at adsorbing fluids. Lucas cites a 2025 IEEE study showing robots achieve only 32% success on standardised spill-wipe tests, while humans succeed 94% of the time. They discuss the tactile sensing work at MIT and the 'dry-to-wet' transition problem. The hosts also touch on why this matters for household robots and industrial cleanup, and offer a brief, natural note on listener support via buy me a coffee dot com slash fexingo.
