Abstract

A method of mowing multiple areas includes training a robotic mower to mow at least two areas separated by a space, including moving the robotic mower about the areas while storing data indicative of location of boundaries of each area relative to boundary markers, training the robotic mower to move across the space separating the areas, and initiating a mowing operation. Training the robotic mower to move across the space separating the areas includes moving the robotic mower to a traversal launch point of a first of the areas and moving the robotic mower to a traversal landing point of a second of the areas. The mowing operation causes the robotic mower to move to the traversal launch point, move from the traversal launch point across the space to the traversal landing point, and then mow the second of the areas.
