EMG-Controlled Wearable
Musculoskeletal Exosuit Assistive Device
Controlling devices that supplement lost strength and coordination, or augment and enhance strength and physical ability of healthy individuals, is an ongoing challenge. As one of four team members, I helped to develop a device that responds to the user’s own muscle activity to augment forces applied by the user.
Objectives
-
Measure and characterize electromyography (EMG) signals produced by the bicep and triceps during common arm movements; classify arm (elbow) movement from EMG signal alone
-
Build a LabVIEW virtual instrument (VI) to process EMG signals, classify them, and drive a motor circuit
-
Design a circuit to translate inputs from the VI into a driving force for the motor in both forward and reverse directions; test specificity of the device
-
Develop and implement a mechanical design that utilized an actuator to contract and allow extension of the user's arm (elbow)
Electronic components and mechanical elements were sourced and adapted to complete the custom design.
