Abstract
A 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 driving modules, 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.
