Coiled bionic tree-climbing robot and working method thereof

The invention relates to a coiled bionic tree-climbing robot and a working method thereof.The coiled bionic tree-climbing robot comprises a head section, a tail section and a plurality of middle sections used for being connected between the head section and the tail section, the head section and the tail section are rotationally connected with the adjacent middle sections, and the adjacent middle sections are connected through middle section linkage assemblies; the middle section linkage assembly comprises hinge plates which are fixedly arranged at the front ends and the rear ends of the middle sections so as to facilitate hinge joint of the adjacent middle sections, linkage shafts which extend front and back are arranged in the middle sections, the two ends of each linkage shaft penetrate through the corresponding middle section, every two adjacent linkage shafts are in connection transmission through a universal joint, and limiting rods protrude out of the left side and the right side of each hinge plate.
