The present application provides a robotic lawn mower. The robotic lawn mower comprises a frame, a first wheel set, and a second wheel set, wherein the first wheel set and the second wheel set are respectively arranged at opposite rear and front ends of the frame, the first wheel set is equipped with driving wheels, and the second wheel set is equipped with omni-directional wheels. The robotic lawn mower further comprises a controller, a first driving module, and a second driving module, wherein the controller is connected to each of the first driving module and the second driving module, the controller controls the first driving module to drive the first wheel set to move so as to provide main power to the robotic lawn mower, and the controller further controls the second driving module to drive the second wheel set to rotate so as to provide auxiliary power for overcoming a resistance generated by the ground when the second wheel set rotates. When the second driving module drives the second wheel set to rotate, the auxiliary wheels of the second wheel set are switched from lateral sliding to lateral rolling during turning, and a friction force between the auxiliary wheels of the second wheel set and the ground may be reduced without an increased moment for the first wheel set due to rotation, which may significantly reduce lawn wear.
