To adapt to the complexity and diversity of an environment and enhance the robustness of the robot grasping tasks, this paper suggests a novel method to realize the hand-eye coordination of a robot based on the 3D object tracking algorithm. In this method, an improved region-based pose tracking algorithm is used to track the poses of the manipulator and the target and simultaneously guide the manipulator movement according to its relative position. For the region-based pose tracking algorithm, a segmentation model is constructed as per the segmentation lines of the local region, and the linear updating method of the model color likelihoods is improved, to accurately track the gripper and the target. Simulation experiments are conducted based on the ROS platform, and the effectiveness and robustness of the hand-eye coordination system are verified in both the simulation and real environments. This method does not need hand-eye calibration and is closer to the human closed-loop control of the “Sensor-Actor” mode with feedback. Concurrently, it provides robots with enough flexibility to deal with versatile tasks in a modifiable environment.
