Establishing an Improved Kane Dynamic Model for the 7‐DOF Reconfigurable Modular Robot

摘要

We propose an improved Kane dynamic model theory for the 7‐DOF modular robot in this paper, and the model precision is improved by the improved function . We designed three types of progressive modular joints for reconfigurable modular robot that can be used in industrial robot, space robot, and special robot. The Kane dynamic model and the solid dynamic model are established, respectively, for the 7‐DOF modular robot. After that, the experimental results are obtained from the simulation experiment of typical task in the established dynamic models. By the analysis model of error, the equation of the improved torque is derived and proposed. And the improved Kane dynamic model is established for the modular robot that used . Based on the experimental data, the undetermined coefficient matrix is five‐order linear that was proved in 7‐DOF modular robot. And the explicit formulation is solved of the Kane dynamic model and can be used in control system.
