The cycle sum of the rotation group of the octahedron was calculated . 正八面體的旋轉(zhuǎn)群的循環(huán)和已算出。
Closed form solution to workspace of double - octahedron variable geometry truss robotic manipulators 二重八面體變幾何桁架機(jī)器人工作空間解析
In the 1960s the most popular pattern had 336 dimpled octahedrons in parallel circles around the ball 在20世紀(jì)六十年代最流行的式樣是336個(gè)八面體酒窩(豆點(diǎn))分布在環(huán)繞球面的平行圓周上。
The error formulas of position and orientation for the octahedron parallel machine tool and the new type of parallel machine tool are set by using perturbation method 利用攝動(dòng)法得出了八面體并聯(lián)機(jī)床和新型并聯(lián)機(jī)床的位姿誤差關(guān)系式。
Based on it , the monte carlo simulation is implemented for the octahedron parallel machine tool , and then the statistical frequency histogram is given 在此基礎(chǔ)上,對(duì)八面體并聯(lián)機(jī)床的位姿誤差進(jìn)行了montecarlo模擬,給出了統(tǒng)計(jì)頻數(shù)直方圖。
