The invention provides a six-wheel-foot type moving robot with three robot bodies, and belongs to the technical field of robots. The problems that an existing moving robot is singular in moving mode and insufficient in moving mechanism flexibility can be solved. The rear end of the front robot body is rotationally connected with the front end of the middle robot body through a front robot body hinge joint. The rear end of the middle robot body is rotationally connected with the front end of the rear robot body through a rear robot body hinge joint. A left front leg and a right front leg are distributed at the left and right sides of the front robot body and both rotationally connected with the front robot body. The left middle leg and a right middle leg are distributed at the left and right sides of the middle robot body and both rotationally connected with the middle robot body. A left rear leg and a right rear leg are distributed at the left and right sides of the rear robot body and both rotationally connected with the rear robot body. The wheel-foot composite type design is adopted by the legs of the robot, and switching of foot type movement and wheel type movement is achieved through a plane four-bar mechanism. The robot has a foot type stable walking function and a wheel type rapid moving function; a mammal-imitating type moving mode and an insect-imitating type moving mode can be achieved through foot type walking, and three steering modes of differential steering, front-wheel steering and pivot steering can be achieved through wheel type moving.
