Robotic Hand Assist for Rehabilitation — Part 1

With the Biomechanics course completed, I moved on to a new project. In this and the next few blogs, I will discuss the same.

The project is ‘Robotic Hand Assist for Rehabilitation’ for rehabilitation through robotic actuation using computer vision.

The idea behind the project is to build a robotic hand-assist, which identifies objects using computer vision and helps a human hand pick and hold the object. This can help patients recovering from nerve damage affecting their hand movement.

The robotic device can be strapped on the human hand using velcro, and has the following components -

1. A 3D printed human hand-like structure with velcro

2. A microcontroller

3. A camera for enabling computer vision

4. A servo motor with strings attached for enabling movement

5. Machine Learning component — a CV library

Further details on the project in the next few blog posts…
