Abstract

A zone mobility system and method for an autonomous device includes a work area within which the autonomous device is intended to operate, one or more electrically separated boundary conductors, each boundary conductor surrounding a work zone within the work area, a transmitter base electrically connected to at least one of the boundary conductors, and a removably coupled transmitter configured to transmit a signal for directing movement of the autonomous device on the boundary conductor wire. The transmitted signal can be adjusted to optimize the power consumption of the transmitter, and a work operation can be commenced utilizing a transmitter interface, and/or utilizing an autonomous device user interface.
