Abstract:
1. A crawler robot, comprising: a triangular-shaped crawler device having parallel triangular frames on respective sides thereof with three rollers respectively arranged at apexes of the frames, crawlers being wrapped around said rollers, wherein the crawlers comprise three rigid components which form a triangle, and a support shaft connecting respective centers of the frames; a subordinate crawler device having crawlers on both sides and being wrapped around rollers of subordinate crawler device frames that are connected to each other, said rollers are arranged at center axes of subordinate crawler device frames; a link having first and second arms rotatably connected to each other with an axis of rotation parallel with the support shaft of the triangular-shaped crawler device, said link having one end fixed on the support shaft of the triangular-shaped crawler device and another end rotatably connected to the subordinate crawler device, such that a rotating shaft of the subordinate crawler device is parallel to the support shaft of the triangular-shaped crawler device, whereby the crawler robot can be formed into three symmetrical sides; and at least one motor configured to drive the crawlers of the triangular-shaped crawler device and the crawlers of the subordinate crawler device and arms of the link independently of each other, wherein the link and the subordinate crawler device are accommodatable within an outer peripheral edge of the triangular crawler device.
