管内監視用カメラの姿勢制御装置。 A camera 3 for monitoring the inside of the pipe 1 is attached to the body 2 for traveling inside the pipe 1 via a universal joint 24 so that the direction can be changed freely.
, a spring 25 biases the posture to face in a certain direction in cooperation with the universal joint 24.
A shape memory alloy 26 is provided between the body 2 and the camera 3, and changes the orientation of the camera 3 in a pre-memorized direction against the biasing force of the spring 25. The shape memory alloy 26 is provided in at least three locations in the circumferential direction of the universal joint 24 across the fuselage 2.
An attitude control device for a camera for monitoring inside a pipe, which is equipped with an energization operation device 22A that brings the energization operation device 22A into a memorized shape regeneration state by resistive heat generated by energization.
