Three Translational Parallel Robot Traiectorv Rope Pulling Preprocessing

The rapid development of motion control technology development and science and technology are inextricably linked. In some of the top sporting events, the staff required to use multiple cameras to shoot from different angles, similar to flying camera can be taken to the high dynamic television screen, this camera platform integrates the latest network technology, computer technology, motion control technology to achieve a greater degree of difficulty. Currently the only American Skycam more mature system and European SpiderCam system which enables the two companies to develop the system in the country in this regard research is still relatively small. This robot is like a camera in a remote-controlled aircraft above installed a camera that can be easily implemented aerial functions. Due to a large area of sports venues, located in the motor pitch four endpoints also relatively large, so how about the control system enables the camera platform in three-dimensional space of stable, accurate, fast motion, becomes a very important content.This paper studies the rope tow camera motion control system hardware and software design and motion control algorithms. Firstly, the status of its development, and to analyze research related technologies; Secondly, select the servo motor performance requirements, software and drivers, and other products, the establishment of the camera cable traction control system model; once again, to analyze the movement of the camera platform. The method can pause the movement, vibration, in order to obtain a continuous, smooth, smooth trajectory, we use the method of pretreatment track, when the track does not appear smooth, affecting the recording quality, we use for circular interpolation its smoothedExperimental results show that:through its trajectory preprocessing, the algorithm can make the camera platform continuously and smoothly through each inflection point, the biggest advantage of this method is to meet its smooth trajectory during exercise, you can not pause, vibration, after pulling the rope to meet the practical needs of the robot system.
