Robot for climbing and/or moving along surfaces

A robot comprising:

• a frame having first and second frame ends, the frame extending longitudinally between the first and second frame ends;
• a track having first and second track ends, the track being suspended below the frame and extending longitudinally between the first and second track ends, the first track end being positioned proximate to the first frame end and the second track end being positioned proximate the second frame end;
• a carrier drivingly coupled to the track, the carrier being translatable along the track between the first and second track ends;
• and
• at least one first foot mounted to the first frame end, at least one second foot mounted to the second frame end, and at least one third foot being rotatably mounted to the carrier so that the at least one third foot is rotatable relative to the track;
• wherein at least one of the at least one first foot, the at least one second foot, and the at least one third foot is linearly displaceable so that the at least one third foot is positionable between first and second positions;
• in the first position, the at least one third foot is positioned closer to the frame compared to the at least one first foot and the at least one second foot, and
• in the second position, the at least one third foot is positioned farther away from the frame compared the at least one first foot and the at least one second foot.
