The invention relates to a four-degree-of-freedom inspection mechanical arm and a control system and a control method thereof. The inspection mechanical arm is mounted at the top end of a load centralframework, and comprises an image acquisition device, a telescopic arm, a first rotating joint, a second rotating joint and a linear driving arm, wherein the telescopic arm is horizontally arranged,one end of the telescopic arm is connected to the top end of the load central framework in a rotating manner through the first rotating joint, and the other end of the telescopic arm is in vertical rotating connection with the upper end of the linear driving arm through the second rotating joint; and the image acquisition device is connected to the linear driving arm in a sliding manner and is driven by the linear driving arm to move upwards and downwards. The four-degree-of-freedom inspection mechanical arm and the control system and the control method thereof, provided by the invention, havethe advantages that circumferential rotating and linear running are combined together, so that the inspection mechanical arm can realize non-dead-corner inspection movement in space, can rapidly andaccurately arrive at a preset position in the working range and can be stably kept at the target position; and then, photographing or video recording is carried out by the image acquisition device carried at the bottom end.
