Here is a robotic arm that can be controlled by brain signals to make life easier for people with disabilities. As Euronews report, David Gathu and Moses Kinyua made this bio-robotic arm and uses a NeuroNode biopotential headset receiver to convert brain signals into an electric currents.
The arm is made of various materials, including recycled wood. It can move vertically and horizontally. This video shows how this bionic arm works.
