Equally, there is the issue of powering the carriages as they climb into space. 同样的,轿厢在向太空爬升过程中的动力问题也是一大挑战。
I watched my heroes with names like Shepard, Glenn and Grissom climb into phone-booth size capsules and then launch into space atop blazing rockets. 我注视着谢泼德、伦和格里索姆等我心目中的英雄爬进电话亭般大小的航天舱,然后在舱下烈火炎炎的火箭推动下进入太空。
The locomotion modes of the prototypes are serpentine crawl, sideslip, side roll, et al on a plane. And most of them have the abilities of raising their heads, climb up steps, crossing low obstacles, et al in the three-dimensional space. 这些样机能实现蜿蜒爬行、侧滑、翻滚、避障等二维平面运动,大部分已经具备抬头、爬台阶、翻越较低障碍等在三维空间中的运动能力。
