Abstract
An automatic working system includes a robotic mower automatically moving and mowing in a working area, and a charging station for docking and charging of the robotic mower; the charging station includes: a charging support and a charging contact mounted on the charging support; and the robotic mower includes a housing, and a charging connector disposed on a lateral side of the housing and connected to the charging contact to receive electric energy when the robotic mower is in a docking position where the robotic mower is docked with the charging station. When the robotic mower is in the docking position, the charging support is located on a lateral side of the robotic mower, and the charging station is open in a front and back direction of the robotic mower to form a passage for the robotic mower to enter and exit the charging station approximately along a same direction.
