Why Robot Arms Still Can't Open a Jar
Episode 38 of The Robotics Podcast tackles a deceptively hard problem: why robot arms struggle with twist-off jar lids. Lucas and Luna break down the physics of rotational grip, the role of compliant torque sensors, and a 2025 MIT study that found even state-of-the-art grippers fail on 30 percent of standard mason jar tests. They contrast industrial automation with the surprising complexity of a household task, and explore what this means for assistive robotics in homes. Specific examples include the torque feedback loop, the problem of varying lid materials, and why a 2026 startup pivot from…
