Prashant Gade, a maker from Pune, India met a 5-year old girl who was missing both of her arms from the elbows down and he created Bio_Nick, a 3D printed electronic prosthetic arm actuated by signals from the foot for her. Motivated by the cause, Gade launched an Indiegogo Campaign with the goal of raising $150,000 and create more prosthetics for the children having similar difficulties in life.
