The invention belongs to the technical field of machine manufacturing, and particularly relates to a wall-climbing robot with a passive compression structure and biomimetic claws. The wall-climbing robot comprises an upper machine body plate, a lower machine body plate, a crank block, the claws and a tail. The upper machine body plate and the lower machine body plate are respectively connected with at least three claws, wherein the claws are symmetrically distributed left and right, and all the claws are connected with the upper machine body plate and the lower machine plate body through elastic leaf springs. The elastic leaf springs deform directionally to provide pre-compression for the claws in a passive mode. According to the wall-climbing robot, the structural design of the one-way elastic claws is adopted, and the claws have the characteristics of being capable of sliding and fixedly clawing and adhering when the wall-climbing robot moves. When the claws slide upward along a wall face along with a machine body, the claws cock backward, and therefore the resistance of upward movement is reduced; when the claws claw and adhere to a wall, the claws are fixed in position due to structural limit, and therefore clawing and adhering are firmer. In addition, the wall-climbing robot is simple in structure, convenient to operate and use, low in manufacturing cost, and suitable for being popularized and applied in related technical fields.
