  • Sensing circuit, logic circuit board, joint control board, main controller board, and robot
    Patent number: 12050101
    Abstract: A sensing circuit (51) including a connection terminal (514) configured to couple with an electrode (32) located on a housing of a mechanical device; and a detection circuit (513) configured to couple with the connection terminal (514) to detect a distance between the electrode (32) and an external conductor or a change of the distance between the electrode and an external conductor by utilizing a capacitance between the electrode (32) and the external conductor or a change of the capacitance between the electrode (32) and the external conductor, thus obtaining an electrical signal representing the distance between the electrode (32) and the external conductor or a change of the distance between the electrode (32) and the external conductor. The sensing circuit can perform non-contact distance detection on a grounded object.
