On November 11, the research team of Professor Hiroshi Yokoi from the University of Electrical and Communications of Japan said that they had developed a mechanical arm that could control movement by using the electric signal of acetylcholine conversion from the muscular nerve.

Actually, it's this product

Professor Hiroshi Yokoi said that this robot arm will be the first to be supplied to 10 disabled people who have lost their forearms, and at the same time observe their use to conduct clinical research on the practical effect and safety of the robot arm. The most important thing is that its use practice is not complicated, and you can master the method in a few minutes. Professor Hiroshi Yokoi also said that he would continue to study the electrical signals generated by the changes in the intramembrane potential of muscle neurons. By classifying the electrical signals, more fine movements of the robot arm could be improved, such as the fingers relaxing and bending at different angles.

The robot arm can also be adjusted through the grip force, and can complete complex finger movements such as grasping, moving objects, and even tying shoelaces. It is basically competent for basic physiological and life movements (don't think about something shy!). However, since the first generation of the robot arm has been developed, the official commercial version is certainly not far away. After entering the commercial market, it will have a more eye-catching shape (after all, people also want to sell money). The same type of robot arm as Edward Ellick is coming!
