Abstract
A charging and control system for a robotic lawnmower, having a circuit loop that includes several wire segments, of which one or more are boundary wire segments that may define or demarcate the boundary of an area within which the lawnmower is permitted to move; a charging voltage signal, for charging the lawnmower's internal battery, and a positioning voltage signal for assisting the lawnmower in determining its current position, are produced respectively by a power supply and a signal generator, which are both provided within the same housing; the two signals are both communicated from this housing over the same wire segments of the circuit loop; a charging station may then be electrically connected to the circuit loop by an end-user so that the charging voltage signal may in use of the system be communicated to the lawnmower when it is docked at the charging station, thus charging the internal battery of the lawnmower.
