KENYA-TECHNOLOGY-ROBOTICS

David Gathu (R), 30, and Moses Kiuna (L), 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.
