Abstract Due to the great mobility and adaptability of hexapod walking robot, and their high performances in various robotic tasks ,the research on it isof mom e ntous scientific significance and practical application value. This thesis addresses body design , gait planning and kinematics analysis ,p olynomial interpolation method offoot t rajectory planning , and obstacle path planning algorithm for hexapod walking robot . In order to solve these problems, a systematic study for the robots is pre sen ted . Firstly, the oval body configuration is chosen based on the structure and motion characteristic of insect , and then drive deeper into the s tability of crawl otion under the tripod gait movement . Secondly, after solving forward and inverse k inematics of swinging leg ,p olynomial interpolation method is adopted to find a better curve offoot trajectory . MATLAB is used todo this simulatio n. The solution shows that swinging leg possesses the excellent ic characteristic under the six-order polynominal function curve. Finally, a brief description of artificial potential field method ( PFM ) and antc olony a lgorithm ( ACO ) expose s the imperfection of them. A new a lgorithm is proposed bin ing PFM with ACO effectively . Simulation results testify the validity of this method for robot path planning .
