Slave part: The slave hand works by converting the electrical impulse sent from the brain through the muscles into information that the robotic hand can read. This is done with myoelectrical sensors, that read the electrical impulse, usually with electrodes, and send the information normally to an Arduino board or similar. Then, when the Arduino board gets this information, it applies the algorithms we have already uploaded and it makes the robotic hand move.

Haptic part: The idea for the haptic part is to use the same physical principle as we did in the slave part but the other way round. This means, we would get the information from the object we are touching with the prosthesis with some sensors, that will send the information to the Arduino board. When it gets the information, it will apply again the algorithms that we have already uploaded and then, using the same or similar channels as the slave part does, it will send the information to the body and the brain so that the person can feel the object.
