Extended Data Fig. 2: WalkON hardware components.
From: Soft robotic shorts improve outdoor walking efficiency in older adults
(a) Computer-aided design of WalkON (b) Inertial Measurement Unit (IMU) sensors stream hip motion data via Bluetooth Low Energy to the control unit. This unit runs the control algorithm on a microcontroller. The output is a velocity command sent to the actuators. The generated motor torque is transferred to the user’s leg via the tendon-driven transmission. (c) The textile structure of WalkON is composed by a waist belt and two thigh harnesses. (d) Anchor points are placed on the belt and thigh harness to guide the artificial tendons.
