The invention aims to provide a small track
robot based on a connecting rod mechanism. The small track
robot comprises a car body, two groups of travelling mechanisms, two groups of connecting mechanisms, a driving motor and a connecting rod motor, wherein the two groups of travelling mechanisms and the two groups of connecting mechanisms are symmetrically arranged at two sides of the car body, the connecting rod motor comprises a first connecting rod motor and a second connecting rod motor, and the driving motor, the first connecting rod motor and the second connecting rod motor are all arranged on the car body. According to the invention, the connecting rod mechanism is introduced into a
robot configuration design, a rigid positioning state and positioning precision of a track connecting frame are improved,
motor load can be reduced by the connecting rod mechanism, a necessary condition is provided for further reducing the size of the robot, connecting rods are provided with multiple holes, the length of fit of the connecting rods can be adjusted according to the specific
topography, the configuration posture and the variation range of the
rod group are changed, and 21 robot configuration change states of the robot can be realized. The small track robot has very good
topography adaptability.
