The Robot Splits Unscrewing Into Two Jobs
DAWN separates screwdriver alignment and insertion from force-controlled removal, with a multimodal classifier deciding when to switch stages.
Summary
DAWN separates screwdriver alignment and insertion from force-controlled removal, with a multimodal classifier deciding when to switch stages.
Automated unfastening remains difficult because a screwdriver must align precisely, engage the fastener and maintain stable force through removal. DAWN uses a diffusion policy for alignment, a multimodal transition classifier and a force-controlled unfastening policy. Tests on a Franka Emika robot reached alignment-and-insertion success comparable to trained human operators and robust removal across unseen scenarios, according to the authors. The abstract does not provide a single overall rate, and the results cover the tested fasteners and setup rather than general disassembly.
