The biggest upgrades from the original Robonaut are R2's thumb, which now have four degrees of freedom (as opposed to three), and its overall speed, which have improved by a factor of four.
相比原始的機(jī)器宇航員，R2最大的升級(jí)是拇指和整體速度；現(xiàn)在的拇指具有四個(gè)自由度（之前只有三個(gè)），同時(shí)速度通過四個(gè)因素進(jìn)行了提升。
The paper introduces kinematics modeling for a kind of four degrees of freedom robot and gains the robots forward kinematics and inverse kinematics by using a simplified method based on this.
討論了一種四自由度機(jī)器人運(yùn)動(dòng)學(xué)模型的建立問題，在此基礎(chǔ)上給出了該機(jī)器人運(yùn)動(dòng)學(xué)正解和運(yùn)動(dòng)學(xué)逆解的簡化求解方法，簡化了求解過程，大大減少了計(jì)算量。

Worn over the legs with a harness that reaches up the back and around the shoulders, X1 has 10 degrees of freedom, or joints -- four motorized joints at the hips and the knees, and six passive joints that allow for sidestepping, turning and pointing, and flexing a foot.
