In this paper, a new bionic quadruped robot was proposed by us. The mechanism of robot we analyzed is as a hybrid series-parallel mechanism, so a new methods for constructing the kinematic model of the bionic quadruped robot very quickly and efficiently was introduced. we analyzed the workspace of the legged mechanism by using geometric composition method and numerical analysis method in the following section. Furthermore, the kinematic model of the parallel mechanism of the multi-motion mode bionic quadruped robot was constructed when the robot was in the stance phase, we also construct and solve the inverse kinematic model of the parallel mechanism of the robot, and the simulation results provide a better method for the robot’s workspace analyzing;Finally, the simulation experiment showed that the method we presented above could provide a good support for the multi-motion mode bionic quadruped robot walking smoothly and automatically.
In this paper, a new multi-motion pattern bionic robot was proposed by us. Though we analyzed the robot as a hybrid series-parallel mechanism, the robot is a wheeled-legged robot, and a new methods for constructing the kinematic model of the special four-bar mechanism of the robot very quickly and efficiently was introduced. Then, the kinematic model of the parallel mechanism of the multi-motion mode bionic robot was constructed when the robot was in the stance phase.
Based on the walking mechanism and the researching method for the serial-parallel mechanism, one multi-sports mode wheel-leg mobile robot is proposed in this paper; Firstly, the serial mechanism model of one leg is constructed, and the method for constructing the kinematic model of the single leg mechanism is studied; Secondly, based on the study of the single leg mechanism, the kinematic model of the parallel mechanism of the multi-sports mode wheel-leg robot is further constructed when the robot is in the support state; Finally, based on the methods and theories discussed above, the experimental prototype mobile robot is constructed, so feasibility of the proposed method is verified.
