摘要: 分析了多指手操作基于运动学速度控制方法和主从规划方法的缺点,指出这些方法都不是真正的协调运动规划方法。通过引入最优抓取所确定的抓取姿态集合约束和衡量抓取质量指标的函数,为多指操作提出了一协调运动生成算法。当初始的抓取姿态是最优抓取时,算法协调各手指运动保持抓取最优,当初始的抓取姿态不是最优抓取时,通过定义抓取质量指标,算法生成手指运动优化抓取姿态。应用HKUST多指灵巧手验证了生成算法。

Abstract: The defects of kinematics-based velocity motion control method and master-slave motion planning scheme of multifingered manipulation are highlighted, respectively, and it is illustrated that they are not coordinated motion planning methods. Then, by introducing constraints of optimal grasping configuration into finger motion generation process, a coordinated motion generation algorithm for multifingered manipulation is proposed. The algorithm generates the coordinated finger motions to keep the grasp in an optimal set when the initial grasp is optimal, or optimize the grasp in an optimal set when the initial grasp is optimal, or optimize the grasp by defining grasp quality measure during manipulation process, when the initial grasp is not optimal. Finally, several manipulation experiments to verify the proposed algorithm are presented.
