This configuration usually requires the motor to be installed in the center of the robot, which not only limits the robot's maneuverability, but also results in low power transmission efficiency when climbing the pool wall, limiting its ability to climb walls. At the same time, due to the high transmission accuracy requirements, its ability to jump over obstacles underwater is also limited. Utility Model Content

[0005] Furthermore, a track tensioning frame is provided between the driving wheel and the driven wheel, and a foam board is embedded in the track tensioning frame.

[0006] Furthermore, the inner peripheral wall of the crawler track is evenly provided with inner racks, and the outer peripheries of the driving wheel and the driven wheel are respectively provided with tooth grooves matching the inner racks of the crawler track, and the inner racks are meshed with the tooth grooves.
