This paper introduces the design of a master-slave robotized system for tele-ultrasound application. The objective of these researches is to design the slave manipulator of this system and its control device (master part). The specification process of the architecture kinematic is based on the analysis of expert’s gesture during ultrasound examinations. These studies have been carried out using a motion capture system. The medical gestures were analyzed in terms of ultrasound probe attitude and used in the definition of the kinematics specifications of the proposed manipulator. The Spherical Parallel Mechanism is selected because its characteristics meet the constraint requirements. The optimal synthesis of spherical parallel manipulators is performed using a real-coded Genetic Algorithm based method. Simulations on the actuator responses of the structure allowed us the validate it. In order to control this robot, we have also designed a haptic device that provides easiness to use as well as force feedback. Its orientation control strategy is based on a use of an adaptative kalman filter which efficiency was demonstrated during experimentations.

本文介绍了基于约束型蛇形拉线机构（CTSM）的新型柔性机器人系统。与达芬奇外科手术机器人和传统柔性机器人相比，基于CTSM的机器人具有更大的工作空间，更高的灵巧度以及刚度可控的优点。该机器人采用Novint Falcon触觉设备进行远程操控， 包括两种操作模式——直接映射模式和增量模式。在每一种模式下，该机器人都可以采用“最大刚度”方案或“最小运动”方案来操控。CTSM的以上优点在仿真模拟和实验中均得以验证。
