A robotic lawn mower is an autonomous robot used to cut lawn grass.
A typical robotic lawn mower (in particular earlier generation models) requires the user to set up a border wire around the lawn that defines the area to be mowed.
The robot uses this wire to locate the boundary of the area to be trimmed and in some cases to locate a recharging dock.
Robotic mowers are capable of maintaining up to 30,000 m2 (320,000 sq ft) of grass.
Robotic lawn mowers are increasingly sophisticated, are self-docking and some contain rain sensors if necessary, nearly eliminating human interaction.
Robotic lawn mowers represented the second largest category of domestic robots used by the end of 2005.
Possibly the first commercial robotic lawn mower was the MowBot, introduced and patented in 1969 and already showing many features of today's most popular products.
