Abstract |
Conventional robots is usually too large to inspect narrow spaces, such as the interior of a nuclear reactor. In this paper, a rigid-flexible serial robot with rigid mechanism and flexible mechanism is designed, and a modified backbone curve method is also proposed for its inverse kinematics.
Different from traditional inverse solution methods, overall configurations of the rigid-flexible serial robot are planned by adjusting shapes of the backbone curve. Firstly, the rigid mechanism is pre-fitted as closely as possible to the determined backbone curve. Secondly, the flexible mechanism is regarded as a biarc and fitted to the determined backbone curve. Parameters of the biarc are solved based on current end position of the rigid mechanism and that of the backbone curve. Thirdly, the rigid mechanism will be re-fitted to the determined backbone curve based on the solved initial position of the biarc. Finally, the work space, typical trajectory, and work scene are all simulated. Results verify the effectiveness of the modified backbone curve method for inverse kinematics of rigid-flexible serial robots. |
