Adaptive and cooperative control of arms and fingers for natural object reaching and grasping, without explicit 3D geometric pose information, is observed in humans. In this study, an image-based visual servoing controller, inspired by human grasping behavior, is proposed for an arm-gripper system. A large-scale dataset is constructed using Pybullet simulation, comprising paired images and arm-gripper control signals mimicking expert grasping behavior. Leveraging this dataset, a network is directly trained to derive a control policy that maps images to cooperative grasp control. Subsequently, the learned synergy grasping policy from the network is directly applied to a real robot with the same configuration. Experimental results demonstrate the effectiveness of the algorithm. Videos can be found at https://www.bilibili.com/video/BV1tg4y1b7Qe/.
