An Indonesian man uses scrap metal to make his own rehabilitation arm.
According to PressTv, Wayan Sumardana, 31, is the owner of a welding workshop in Bali, Indonesia. Sumardana completely paralyzed the left arm, the result of a stroke six months ago.
During his studies in mechanical technology at vocational secondary schools, Sumardana himself researched and searched for information to build a robotic arm, helping him to move his left arm.
The device consists of a hydraulic frame attached to the arm, connected to the electrode ring worn on the head. Sumardana can use the idea of controlling robotic arms through electrical impulses in the brain.
