Abstract： This paper presented a bandwidth allocation algorithm for video transmission in robot remote control system. There are multiple video sensors equipped on the robot. The transmission weight of each video was calculated according to the current tasks being executed by the robot. In multiobjective optimization, the algorithm distributeed the transmission bandwidth fairly to each video sensor based on their weight, and could guarantee that the total transmission bandwidth never exceeds the transmission bandwidth provided by the network. The transmission bandwidth was controlled by modifying the resolution and frame rate of the video acquisition. The algorithm reduced the lose rate of frames caused by network congestion, thus protects the integrity of realtime video, makes the  teleoperation tasks of the system complete which depend on the visual image quality. The algorithm is tested by inspection tasks in an actual power plant environment. Smooth video transmission service has been provided and the practicability of the algorithm is also verified.
