Kinematic calibration is an effective and economical way to improve the accuracy of the parallel robot. A new calibration method using an orientation constraint is presented in this paper. The main idea is to keep two attitude angles of the end-effector constant at different measurement configurations with the help of a commercial biaxial inclinometer. Repeatability and resolution of the inclinometer...
This paper presents a discrete learning controller for vision-guided robot trajectory imitation with no prior knowledge of the camera-robot model. A teacher demonstrates a desired movement in front of a camera, and then, the robot is tasked to replay it by repetitive tracking. The imitation procedure is considered as a discrete tracking control problem in the image plane, with an unknown and time-varying...
