Abstract
A system for remotely operating a machine, such as a mine vehicle, includes at least one first emitter for emitting a first signal corresponding to a first zone adjacent to the machine. A transmitter is provided for receiving the first signal emitted by the emitter, the transmitter being adapted for issuing commands for controlling the machine and also indicating the presence of the transmitter in the first zone. A controller is also provided for controlling the machine based on the control signals from the transmitter based on the presence of the transmitter in the first zone. Related methods are also disclosed.
