A drive track (38) for a vehicle includes a frame (80), a drive pulley (86) rotatably coupled to the frame (80) and coupled to a drive (92), an idler pulley (88) rotatably coupled to the frame (80), and a track wheel (96) disposed about the frame (80). The track wheel (96) includes a continuous belt (98) and a plurality of link assemblies (100) coupled to the belt (98). Each link assembly (100) includes a plurality of alignment elements (102) configured to engage with a surface. The alignment elements (102) are configured such that rotation of the belt (98) defines a first movement direction of the vehicle, and are further configured to permit movement of the vehicle in a second movement direction perpendicular to the first movement direction under the weight of the vehicle. The vehicle may be a robotic device (34) for repairing a leading edge (26) of a wind turbine blade (20) and the drive track (38) allows the device (34) to remain aligned with the leading edge (26), such as a curved leading edge (26).

Provided herein is an apparatus for attraction and disposition of reptiles, including a heat source disposed on or near the manipulator arm or on a platform; a manipulator arm comprising a gripper and an arm imager, wherein the manipulator arm is disposed on the heat source or on the platform; and one or more control units connected physically or wirelessly to the heat source, the manipulator arm, the arm imager, or a combination thereof.
