Autonomous working device and system

The invention provides an autonomous working device and system. The autonomous working device may include: a body; the driving assembly is connected with the machine body and is configured to drive the autonomous working device to move according to the driving instruction; the sensor assembly is configured to generate sensing data based on the collected information; the controller is electrically connected with the driving assembly and the sensor assembly and is configured to receive input of an approach instruction; in response to the approach instruction, executing an approach control process; wherein the approach control process comprises the following steps: outputting a corresponding driving instruction according to the sensing data so as to control the autonomous working device to move from a vehicle for transporting the autonomous working device to a first moving track of the ground of a non-working area; obtaining map data of a working area of the to-be-executed working task; and outputting a correspo
