Surgical instrument sorting is a repetitive work with a high risk of infection, which requires medical staffs to classify them after cleaning. Currently, the surgical instrument sorting is usually accomplished by medical staffs' manual operation. It is a time costing work, which may cause operators' fatigue even classification errors. Meanwhile, surgical instruments are relatively sharp and often...
Segmenting 3D objects from a set of disordered point cloud is always one challenge work in Bin-pi cking systems. In this paper, an easy and valid algorithm is proposed to solve this problem. The point data set obtained from a low-cost depth camera, RealSense, can be quickly filtered to be a much clean compact one, significantly saving the computing resources. The filtered points set is next divided...
The ability of the underactuated adaptive gripper is to envelop the objects according to its geometric shapes. It is known that robotic grippers are a nonlinear system, and it is difficult to set up an appropriate mathematical model, so it is hard to execute a precise control. In this paper, an underactuated gripper with two adaptive fingers is presented, and a Copley servo controller (Accelnet Micro...
Flexibility of the assembly system is crucial to the rapidly changing market, for that a family of products fabrication need to be implemented on a single production line. This paper presents a novel flexible fixturing system for sheet metal part assembly, the system is composed of reconfigurable fixtures use parallel robots as programmable fixture elements so that they can be reprogrammed for different...
