An interface 12 for a vehicle 10 is configured to be displaceable by a field generated by a linear induction motor (LIM) 14 having a primary coil 16 for moving the vehicle, wherein the interface wirelessly receives electrical energy via a receiver (e.g. tertiary coil 22) for charging a power supply (e.g. battery 24) of the vehicle, the energy being transmitted from an energy transmitter (e.g. transmission coil 26). Therefore, the LIM induces movement of the interface without contact and simultaneously transfers power wirelessly to the interface. The interface may have a plate 20, made of metal that is displaceable by a magnetic field generated by the LIM, the plate functioning as a secondary coil 18. A vehicle transceiver 28a and a LIM transceiver 28b provide a communications channel for sending and/or receiving data regarding energy levels of the vehicle power supply and/or a set of instructions for the vehicle to follow. The transceivers can transmit and receive data via the coils. The vehicle may operate autonomously and perform a set of tasks in a defined zone. The vehicle may move using power from the vehicle power supply, or it may commute along a predetermined route 38 to another zone, being moved by displacement of the interface by a LIM.
