Two Kenyan inventors have created what is said to be the world’s first bio-robotic arm operated by brain signals. The invention, which is controlled by brain signals, has been billed as a game-changer in the lives of disabled people in Kenya.

David Gathu and Moses Kinyua’s invention differs from most prosthetic technology which is powered by a person’s muscles. The arm works by converting brain signals into an electric current by a “NeuroNode” biopotential headset receiver. NeuroNode biopotential was originally invented to help people suffering from paralysis and speech loss.

The electric current is then driven into the robot’s circuitry, which gives the arm its mobility, according to Euro News. The arm has several component materials including recycled wood and moves vertically and horizontally.
