FUM-NEXA knee exoskeleton shown as a CAD design and as the manufactured prototype.

Adaptive sit-to-stand assistance for the FUM-NEXA knee exoskeleton

A fuzzy Strength Index adapts knee-exoskeleton torque during sit-to-stand in real time on a Raspberry Pi running ROS2. In a five-person engineering study, measured muscle effort fell by 30% at slow speed.
