Brain-Computer Interface (BCI) is a device that controls robotic arms/legs through cognitive responses or monitoring brain activity. This is mainly aimed at people with mobility problems or issues with motor functions. The device will record the electric responses/signals in the brain and convert the data into the robotic arm/leg to function as if it were a real arm/leg. For the device to work, it has to be implanted into the brain and to connect wirelessly to the robotic arm/leg. It is currently still in progress, but it will soon be fully functional. There have been prototypes already created and tested on animals (monkeys and pigs), with very promising signs. However, the main issue is for human usability. The size of the chip/circuit will need to be significantly reduced in order for it to be safe. How Brain-Computer Interfaces work
