Abstract
A robotic lawn mower interaction station may be adapted to receive an oncoming robotic lawn mower. The interaction station includes a charging tower with a charging transmission arrangement that is adapted to provide a charge current, delivered from a station charging unit, to a charging reception arrangement of a docked robotic lawn mower. The interaction station includes a reception ground plate that extends from the charging tower towards a frontmost part, included in an entering edge. The ground plate is constituted by a plate part and one ridge part that extends a certain ridge height from the plate part.

A computer-implemented method performed by a robotic lawn mower control unit, where the method comprises controlling a front-wheel driven robotic lawnmower to:
- move in a forward direction (F) and approach a robotic lawn mower interaction station having a charging transmission arrangement,
- stop at a distance from the charging transmission arrangement;
- turn in a rotational movement such that at least one rear wheel enter a reception ground plate of the interaction station;
- continue turning such that at least one rear wheel passes a ridge part formed in the reception ground plate;
- detect that at least one rear wheel has passed the ridge part formed in the reception ground plate;
- and then to stop the turning;
- the method further comprising controlling the robotic lawnmower to reverse towards the charging transmission arrangement;
- and to
- dock the robotic lawn mower such that electrical contact is established between the charging transmission arrangement and a charging reception arrangement of the docked robotic lawn mower.
A robotic lawn mower interaction station adapted to receive an oncoming robotic lawn mower, wherein the interaction station comprises a charging tower with a charging transmission arrangement that is adapted to provide a charge current, delivered from a station charging unit, to a charging reception arrangement of a docked robotic lawn mower, wherein the interaction station comprises a reception ground plate that extends from the charging tower towards a frontmost part, comprised in an entering edge, wherein the ground plate is constituted by a plate part and one ridge part that extends a certain ridge height (h) from the plate part.
