Abstract

Herein a self-propelled robotic lawnmower (1) Is disclosed comprising a lawnmower chassis (3.1, 3.2) and wheels (5.1-5.4) arranged at the lawnmower chassis (3.1, 3.2). The wheels (5.1-5.4) are arranged to support the lawnmower chassis (3.1, 3.2) during operation of the lawnmower (1). The wheels (5.1-5.4) comprise at least a first wheel (5,1) and a second wheel (S.2), wherein the first and second wheels (5.1, S.2) are arranged at opposite lateral sides (6.1, 6.2) of the lawnmower chassis (3.1, 3.2). At least the first and second wheels (5.1, 5.2) are arranged at the lawnmower chassis (3.1, 3.2) with a negative camber angle (a).
