David Gathu (L), 30, and Moses Kiuna (R), 29, both self-taught innovators, demonstrate the operation of a bio-robotic prosthesis using brain-signals created using salvaged electrical components, mechanical parts, plywood and rubber bits at their makeshift laboratory at Thogoto village in Kikuyu municipality, Kiambu county, on January 31, 2023. Cousins Moses Kiuna, 29, and David Gathu, 30, created their first prosthetic arm in 2012, after their neighbour lost a limb to an industrial accident. But their latest invention is a significant upgrade. The device uses a headset receiver to pick up brain signals and convert them to an electric current, which is then sent to a transmitter that wirelessly relays commands to the arm, prompting it into action.
