ELBOW JOINT ACTUATION ASSISTIVE DEVICE

JULY 2014 | ZINE LAB | MNIT JAIPUR

OBJECTIVE

Building a device that could assist elbow joint movements for people suffering with weak joints mainly because of fractures

METHODOLOGY

The system had a unique design that had an electric motor driven external elbow joint exoskeleton. The externally powered joint could be controlled as per the user's will. The design was unique because of several reasons

• The design was made with special grooves for optical encoder based rotation-angle detection
• The complete design was on 3D printer using ABS plastic
• The rotation was controlled using a flex sensor worn on a finger whose motion was mapped to that of the device

RESULTS

•   The device was useful in rehabilitation of elbow joints
•   The system performed as per user's will with ease
