Autonomous mobile multifunction device for mowing e.g. lawn, has control and processing unit that processes the data received by receiving unit and signal receiving modules, to determine position of multifunction device

摘要

The multifunction device (1) has a receiving unit (2) for receiving satellite data from a global positioning satellite system (5), and signal receiving modules for receiving radio signals, ultrasonic signals, visible or non-visible light signals transmitted by transmitter (4) installed in building. A control and processing unit processes data received by receiving unit and modules, to determine position of multifunction device. An optimum movement and driving directions of working tool is determined and a drive system (3) is controlled, based on position of multifunction device.
