摘要： 文中介绍了Baxter机器人控制方式和一种基于势函数的视觉伺服控制机器人手臂跟随运动的方法,为服务机器人和协作机器人的发展提供了技术支撑。首先通过基于OpenCV的颜色检测方法从摄像机获取跟随物体的相对方位信息,然后通过ROS系统对机械臂进行运动控制,最后利用视觉与机器人配合完成机器人手臂跟随系统设计。通过对跟随轨迹精度分析表明,眼内视觉传感器的布置可以提供相对较高的精度,避免视觉碰撞,从而实现准确的跟随运动。利用实验验证了该方法的有效性。

Abstract: This paper introduces the control mode of Baxter robot and a potential function based visual servo control method of robot arm following motion,which provides technical support for the development of service robot and cooperative robot.In this paper,the relative orientation information of the following object was obtained from the camera based on OpenCV color detection method,and the manipulator was controlled by ROS system.Finally,vision and robot were used to complete the design of the robot arm following system.By analyzing the precision of the following track,it is shown that the arrangement of the intraocular vision sensor can provide relatively high precision and avoid visual collision,thus realizing accurate following motion,and the effectiveness of the method is verified.

Key words: Baxter, OpenCV, visual servo, motion control
