Continuous path (CP) control was researched on an Internet-based two degrees-of-freedom robot arm in this paper. First, the condition needed to realize the continuous path control was analyzed. The important parameter “the highest resultant speed” was calculated considering the existence of network-delay. Then the relation between the linear interpolation numbers and errors of the four-leaf rose curve...
Based on a 2-DOF manipulator, this paper realizes a closed loop control system by adding image transmission module and image processing module to an semi-closed-loop networked control system. The camera calibration and end-executor recognition are carried out on the server. According to the result of calibration, coordinates of the end-executor in a fixed reference frame are computed, and the image...
