Summary
A paper on arXiv describes PACT, a method for designing tendon-driven robotic hands. The source explains that humanoid hands need enough force, speed, and backdrivability within a human-scale size, and that tendon drives move actuators to the palm and forearm. It argues that routing paths, moment arms, and capstan dimensions jointly affect both force and joint speed, so choosing them one after another favors one requirement over the other. The snippet is truncated, so the paper's specific results are not stated here.

What happened
Humanoid robotic hands must provide sufficient force, speed, and backdrivability within a human-scale envelope. Tendon-driven transmissions address this challenge by relocating actuators to the palm and forearm, but routing paths, moment arms, and capstan dimensions jointly determine both force capability and...
Why it matters
Engineers building humanoid or dexterous robotic hands may need to design routing, moment arms, and capstan sizes together rather than in sequence. The approach targets a trade-off between grip strength and movement speed that affects how capable such hands can be. Readers should check the full paper for its reported results and whether the method has been tested on physical hardware.
