Abstract

A robotic device (10) comprising four or more legs (14) which is configured to crawl over a surface of a wind turbine blade (2) for inspection of and/or maintenance of the wind turbine blade, wherein the robotic device comprises a body (12) defining a longitudinal axis, the robotic device further comprising a row of legs (14) arranged on opposite sides of the body, the legs each comprising two or more articulated limb segments (16, 18) and a foot (40), the articulated limb segments comprising an upper limb segment (16) and a lower limb segment (18), wherein the upper limb segment (16) is joined to the body (12) by a first articulated joint (22), the lower limb segment (18) is joined to the upper limb segment (16) by a second articulated joint (20), and the foot (40) is joined to the lower limb segment by a third articulated joint (46), and wherein the articulated limb segments (16, 18) are configured to enable the robotic device (10) to straddle over a leading edge (3) of the wind turbine blade (20) with the feet of opposing legs positioned on opposite sides of the leading edge.
