英文摘要: |
This paper built a multi-joint manipulators model with a set of nonlinear location equations on a 6-DOF
surgical robot. Further, it presented a calculation method of these nonlinear location equations based on Lyapunov
stability theorem. With this method the operation of nonlinear location equations was simplified and simulated easily,
which was benefit for high-speed manipulator. Experimental results show that the algorithm is suitable for solving multi-
joint manipulators nonlinear location equations. and it has a higher accuracy and convergence speed. |
