Abstract
A robotic work tool (1) is disclosed configured to operate in an area in an autonomous manner. The robotic work tool (1) comprises one or more rechargeable batteries (5) and a contact plate (3) configured to transfer electricity from a contact (4) of a docking station (8) to the one or more rechargeable batteries (5). The contact plate (3) comprises an edge surface (3′) configured to abut against the contact (4) of the docking station (8) upon movement of the robotic work tool (1) relative to the docking station (8) along a docking direction (d1). The contact plate (3) comprises a number of sections (s1-s5, b1-b4) each being angled relative to the docking direction (d1). The present disclosure further relates to a robotic tool system (10) comprising a robotic work tool (1) and a docking station (8).

A robotic work tool configured to operate in an area in an autonomous manner, wherein the robotic work tool comprises:
- one or more rechargeable batteries, and
- a contact plate configured to transfer electricity from a contact of a docking station to the one or more rechargeable batteries,
- wherein the contact plate comprises an edge surface extending along an abutment plane,
- the edge surface being configured to abut against the contact upon movement of the robotic work tool along a docking direction,
- and wherein the contact plate comprises a number of sections each being angled relative to the docking direction with at least one angle in a plane parallel to the abutment plane such that a contact area between the edge surface and the contact moves in a direction orthogonal to the docking direction upon the movement of the robotic work tool in the docking direction.
