Sensing circuit, logic circuit board, joint control board, main controller board, and robot

A robot control system comprising a sensing circuit, a logic circuit board, a joint control board, and a robot main controller board, wherein:

• the sensing circuit is configured for an electronic skin of a device, comprising a connection terminal connected to an electrode located on a housing of a mechanical device;
• a detection circuit is connected to the connection terminal to detect a distance between the electrode and an external conductor by utilizing a capacitance between the electrode and the external conductor or a change of the capacitance between the electrode and the external conductor, thus obtaining an electrical signal representing the distance between the electrode and the external conductor or a change of the distance between the electrode and the external conductor;
• the logic circuit board is configured to couple with the sensing circuit;
• and
• the joint control board is configured to couple with the logic circuit board, and comprises a motor drive circuit configured to drive a robot to move.
