Abstract
Robotic work tool () configured for improved turning in a slope (S), said robotic work tool comprising a slope detector (), at least one magnetic field sensor (), a controller (), and at least two driving wheels (″), the robotic work tool () being configured to detect a boundary wire () and in response thereto determine if the robotic work tool () is in a slope (S), and if so, perform a turn by rotating each wheel (″) at a different speed thereby reducing a risk of the robotic work tool () getting stuck.
