This invention discloses a miniature bidirectional crawling robot based on vibration mode control, comprising a support frame, a drive device, and a power system. The power system consists of an elastic element, a flexible four-bar linkage, and crawling feet. One end of the elastic element is fixed to the support frame, and the other end is connected to the flexible four-bar linkage. The other end of the flexible four-bar linkage is fixed, with the crawling feet connected in its middle section. The elastic element can generate different vibration modes under different frequency excitations. The drive device can drive the elastic element to undergo forced vibration, which in turn drives the crawling feet relative to the ground through the flexible four-bar linkage to achieve bidirectional crawling. When the power system is in first-order vibration, the robot crawls forward; when the power system is in second-order vibration, the robot crawls backward. Thus, by changing the vibration mode of the elastic element, the robot can be controlled to achieve bidirectional crawling motion. This invention has a simple structure, high reliability, convenient bidirectional motion control, great miniaturization potential, and fast crawling speed.
