摘要
提出了一类针对细长形物体的高精密操作的运动规划方法.首先建立了机械手与显微相机之间的坐标转换关系,以及对力坐标系与操作手之间的转换矩阵标定;再借助约束刚性多体模型构建物体与机械臂之间的运动学关系,提出了采用混合控制策略.利用力反馈确定物体姿态和物体参数,利用单目显微视觉反馈确定物体的位置信息,从而实现对细长形物体的高精密运动控制.实验结果验证了该方法的有效性.
A motion regulation method for high precision manipulation of thin-and-long was proposed.First,the transitional relationship between the coordinates of manipulators and microscopes was modeled,and the rotational matrix between the coordinates of force sensor and manipulators was calibrated.Then,the kinematics relationship between the object and the manipulators was constructed in terms of multiple rigid constraint models.To realize the high precision manipulation of thin-and-long objects,a hybrid control strategy was presented,in which the force feedback was used to determine the object posture and parameters and the visual feedback from a monocular microscope was employed to regulate the object position.Experimental results verify the validity of the proposed method.
