Why Robot Arms Still Can't Screw a Lid On Tight
Episode 21 of The Robotics Podcast with Fexingo dives into a deceptively hard problem: tightening a bottle cap. Lucas and Luna break down why torque control, compliance, and tactile sensing make this simple human gesture a nightmare for industrial robot arms. They explore a 2025 paper from MIT's CSAIL that benchmarks six robot arms on cap-tightening, revealing that even the best models fail 40% of the time on inconsistent caps. The hosts discuss the physics of friction, the limits of current force-torque sensors, and why this matters for food and pharma packaging. They also touch on how…
