The Exosuit Learned the Wrist in 140 Seconds
A personalized inverse model cut interaction torque by up to 73 percent without force or physiological sensors on a test rig.
Summary
A personalized inverse model cut interaction torque by up to 73 percent without force or physiological sensors on a test rig.
The controller models pneumatic artificial muscles with hysteresis and linear dynamics, personalizing the inverse plant from 140 seconds of movement data. On a wrist test rig it reduced interaction torque by up to 73 percent and key muscle activation by up to 47 percent across tested speeds. The result is task-agnostic assistance in an emulated setup; clinical benefits and everyday wear remain unproven.
