The Ubokobong Bionic Arm pairs muscle-controlled movement with a hyper-realistic look designed for Black amputees, and it is already in use by clients in 56 countries. It grew from two brothers' own experience after one lost his fingers in a fireworks accident and could not find a prosthetic that matched his skin tone.
