Claim 0:
1. A robotic device comprising four or more legs which is configured to crawl over a surface of a wind turbine blade for inspection of and maintenance of the wind turbine blade, wherein the robotic device is programmed to recognize automatically a leading edge of the wind turbine blade and then control a movement of the four or more legs autonomously such that the robot device crawls along the leading edge of the wind turbine blade to conduct inspection and maintenance of the leading edge of the wind turbine blade,
wherein the robotic device comprises a body defining a longitudinal axis, the four or more legs comprising a row of legs arranged on opposite sides of the body, the legs each comprising two or more articulated limb segments and a foot, and the articulated limb segments comprising an upper limb segment and a lower limb segment,
wherein the upper limb segment is joined to the body by a first articulated joint, the lower limb segment is joined to the upper limb segment by a second articulated joint, and the foot is joined to the lower limb segment by a third articulated joint,
wherein the limb segments are articulated in a way that enables the robotic device to straddle over a leading edge of the wind turbine blade with the feet of opposing legs positioned on opposite sides of the leading edge, and
wherein the robotic device comprises a chamber of resin with a device for applying the resin as a coating to a damaged region of the wind turbine.
