Myoelectric transradial prosthesis prototype with intuitive single-grasp capability

Abstract

An electromyography (EMG) acquisition/analysis circuit was created to facilitate intuitive, real-time control for a human/computer interface (HCI). Electrical activity in the user's target muscular region, which exceeds a specified threshold, translates into actuation of the designated primary grasp for the commercial product, MechaTE robotic hand. The interface was successful in a real-time demonstration where a user was able to catch a billiard ball moving across a pool table. This prototype provides the foundation for a more advanced HCI, with dexterous, multi-grasp capabilities. Future work aims to create a novel non-invasive brain computer interface (BCI) which can be used to restore partial functionality to transradial amputees.
