In this paper, we propose a novel two-stage approach on picking an object from randomly stacked pile. We especially consider a situation where it is difficult for a 3D depth sensor to identify the pose of objects such as shinny ones and black ones. For such objects, our method first roughly grasps some of the objects from the pile without using the visual information and roughly place them onto a working table. After some of the objects are placed on a working table, a robot picks one of them by detecting the 2D position of objects placed on a working table by using the 2D RGB image. We performed experiments for several objects with different shape and weight. Through experimental study, we confirmed that a robot can identify the position of one of the objects after the objects are placed on a working table and that one of the objects can be successfully picked up by a robot.

To extend the paralyzed fingers of a stroke victim with hemiplegia, we have proposed a low-dimensional control system for a robotic finger which can grasp an object between the robotic finger and the paralyzed human fingers. In this study, we newly propose an extra finger that can face multiple fingers with low-dimensional control. This can be realized by adding a rotational joint for moving the base of the robotic finger where it is controlled by the common low-dimensional synergy controller. Experimental results showed that the proposed extra finger could realize 33 grasping postures and 4 peg manipulation patterns.
