本研究主要探討「三節式線性滑軌靜態精密度與準確度量測」，係在國內外有許多移動式機器人競賽將用到此滑軌。競賽項目琳瑯滿目，若是功能性之競賽，主要重點是準確(accuracy )、快速(speed) 與壽命(life cycle)，只有單純地追求準確(accuracy )是不夠的，只有單純地追求快速(speed)也是不行的，無法完成競賽也無意義，因此本文為結合實務技術與工程科學理論，以靜態力學之角度探討精密度(precision)與準確度(accuracy)間的調配達到最佳競賽之功能。
本研究將發展一套有系統、有效調整變數的方式，探討三節式線性滑軌運動之過程產生之精密度與準確度，並在手臂上下左右之4個方向，施以一定力量測三節式線性滑軌之線性、重複性與再現性，以確定其精密度與準確度。依此找出最大施力5N時，滑軌B於方向3夾持伸出量500mm的變動量0.6245mm，此變動量最小，精密度高。由此可知三節式線性滑軌在用於移動式機器人適合此施力方向裝配。
The research proposes measurement of static precision and accuracy for a 3-fold Ball Bearing Slides as a linear motion system. By the mobile robot competitions, a 3-fold Ball Bearing Slides are often used as a linear motion system. The functions of mobile robot competitions are normally not only accuracy and speed, but life cycle is importance too. In the research, the principle of science and practical technology will be integrated to investigate the precision and accuracy of a 3-fold Ball Bearing Slides as a linear motion system. The optimal function for a mobile robot competition of the 3-fold Ball Bearing Slides as a linear
motion system will be adjusted finally.
An experimental setup will be developed for the measurement of static precision and accuracy for a 3-fold Ball Bearing Slides as a linear motion system. The static precision and accuracy of four direction for a 3-fold Ball Bearing Slides will be measured by the developed experimental setup. The experimental result shows that the highest precision is 0.6245 mm, that is located in direction 4 by the parameters of stroke 500mm, lording force 5N.
