Driven gears are meshed on both sides of the driving gear. Each driven gear is installed on the wheel axle of the track wheel group, thereby realizing the driving of the track wheel group.

[0037] This design can drive four track wheel sets with two motors, simplifying the product structure and reducing product costs.

[0038] A crawler-type photovoltaic panel cleaning robot includes a cleaning robot body equipped with a navigation system.
