Brain Controlled Robotic Joint

Inspiration

Amputees face physical and emotional challenges in their day-to-day life, and their struggle is immeasurable. To solve this problem, I'm presenting a robotic joint, that can be used as a limb (once combined with prosthetics) and can help them control an artificial arm or leg using their brain. Although the headset contains only a single channel, it can still be a stepping stone to cutting-edge technology.

What it does

It is a brain-controlled robotic joint, so the user can control their artificial limb using their brain. Some practice might be required to consider focus levels. If more electrodes are added to it, it can be highly accurate as well.

How we built it

Challenges I ran into

Interfacing the headset and configuring it further was a bit troublesome.

What we learned

I learned about EEG, had to go through some research papers, and also gained motivation to solve real-world problems

What's next for Brain Controlled Robotic Joint

I'll try to gather funds and increase the number of electrodes in my headset, to convert it into a fully-fledged prosthetic arm that can be used in real time. (basically turn this prototype into a product)
