Application of automatic sorting technology in logistics warehouse is considered as one of the development goals with the rapid development of robot technology. However, packaging products with different shapes is usually done by human instead of robots. The reason why robot automation is difficult to implement in operation is that single robot hand could not deal with items with different shapes and sizes. In this study, by imitating the opening and closing of the tree frog's palm to help items stably stand on different surfaces, a four-claw robot hand with vacuum suction cups on their tips is proposed. Robot hand consists of three fingers with sucks and a thumb, and it can adopt different grasping strategies according to objects with different shapes and sizes. A prototype of robot hand was fabricated by a 3D printer. Besides, simple automatic grasping system is established, grasping experiment is accomplished.
