Abstract: The invention discloses a binocular robot for bridge underwater detection based on 5G communication. The robot includes a body, a base, a power arm, a video collection component, a communication component and a power component. The underwater part of the bridge may be collected in the form of a video by the configured video collection component, and the robot may be driven by the power component to move underwater. Driven by a first motor, a binocular camera may rotate to observe various orientations underwater, and meanwhile may drive a cleaning component coordinated with an electric top block to wipe the lens of the binocular camera, so that the video information may be collected clearly underwater. Finally, the video information may be transmitted to a worker on the water through the communication component to achieve the effect of remote detection, which saves the underwater detection cost and improves detection efficiency.
