Abstract

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.

Description

technical field [0001] The invention relates to a six-wheel-foot composite mobile robot, which belongs to the technical field of robots. Background technique [0002] The ground movement methods mainly include wheel type, crawler type, foot type, peristaltic type and vibration type. Wheeled mobile has the advantages of fast movement speed and high mobile efficiency, but its ability to overcome obstacles is poor and can only adapt to relatively flat ground; crawler mobile can pass small obstacles, but the passability of rough terrain is still insufficient, and the transmission efficiency is low; Foot-like walking has strong terrain adaptability and obstacle-surmounting ability, but its walking speed is slow and its energy efficiency is low. Therefore, each type of movement has its own specific terrain conditions, and the wheel-foot compound movement combines the advantages of wheel and foot movement. The flat terrain uses the wheel to pass quickly, and the complex terrain us...
