    摘要:

    主从控制是实现机器人辅助穿刺操作控制的关键方式之一。然而,由于穿刺辅助机器人感知和反馈方式的复杂性和差异性,手术机器人系统主从控制的快速构建存在很大的挑战。故提出一种面向穿刺手术机器人主从控制的快速构建方法,实现主从运动映射的快速构建和主从控制的快速实施。建立物体运动坐标系,并定义和构建物体运动映射坐标变换的相对位置变换链,实现对物体运动坐标变换的显性表达和运动映射的快速构建;进一步提出基于直观性映射模型的主从运动映射快速构建策略,针对多种感知反馈的从手对象,快速构建主从运动映射的相对位置变换链,实现主从控制多重坐标变换的运算,进而快速实现定制化和多样化的主从控制。进行实验研究,利用提出的主从控制快速构建方法分别对两种主手对象和两种从手对象的4种主从控制进行快速构建与实施。实验结果表明:主从控制映射的快速构建策略,可以实现对多种感知反馈主从运动映射的快速构建,得到了4种主从运动映射的相对位置变换链,每一种变换链表示一种独立的主从控制,以适应不同应用场景的需求;通过相对位置变换链的多重坐标变换的控制计算,实现了主从控制的快速实施,验证了所提的主从控制快速构建方法的可行性与实用性。

    Abstract:

    Master-slave control is one of the key methods for realizing the control of robot-assisted puncture operations. However, due to the complexity and diversity of puncture-assisted robots as well as their sensing and feedback methods, there exist significant challenges in the rapid construction of master-slave control for surgical robot systems. This paper proposes a rapid construction method for master-slave control of puncture surgical robots, which enables a rapid construction of the master-slave motion mapping and a rapid implementation of the master-slave control. Firstly, a coordinate system for the object motion is established, and the relative position transformation chain for the coordinate transformations of object motion mapping is further defined and constructed to realize explicit expression of the coordinate transformations of the object motions, and thus achieving the rapid construction of the motion mapping. Secondly, a rapid construction strategy for the master-slave motion mapping based on an intuitive mapping model is proposed. For the slave objects with various sensing and feedback modes, the relative position transformation chain for the master-slave motion mapping is quickly constructed to enable the calculation of the multiple coordinate transformations for the master-slave control and to further realize the rapid realization of the customized and diversified master-slave control. Experimental studies are then conducted using the proposed method, and the rapid constructions and implementations of 4 types of the master-slave control for two master objects and two slave objects are implemented, respectively. The experimental results show that: The proposed rapid construction strategy for the master-slave control mapping can realize a rapid construction of the master-slave motion mapping with various sensing feedbacks, and 4 relative position transformation chains for the master-slave motion mapping are obtained, where each transformation chain represents an independent type of the master-slave control to accommodate the requirements of different application scenarios; through the control calculation of the multiple coordinate transformations based on the relative position transformation chains, the rapid implementation of the master-slave control is achieved, which verifies the feasibility and practicality of the proposed rapid construction method for the master-slave control.
