Applications outside the Earth’ s atmosphere are clearly
a good fit for robots. It is dangerous for humans to get to
space, to be in space and to return from space. Keeping
robots operating reliably in space presents some unique
challenges to engineers. The ultra-high vacuum in space【M1】______
prevents the use from most types of lubricants. The【M2】______
temperatures can swing wildly depending on whether the
robot is in the sun light or shade. But, of course, there is【M3】______
almost no gravity. This is actually more of an opportunity
than a challenge and leads to the possibility of some unique
designs. The conceptual robot has 21 independent joints. On
earth it would be possible for this robot to support its own【M4】______
weight, but in space, the design presents some unique
capabilities. The robot can reach around obstacles and
through out port holes. The robot also possesses a huge【M5】______
degree of fault tolerance. It can continue to operate with
excellent dexterity even after several joints fail.
NASA decided to develop a $288-million Flight
Telerobotics Servicer(FTS)in 1987 to help astronauts
assemble the Space Station, which was growing bigger and
complex with each redesign. Shown here is the winning【M6】______
robot design by Martin Marietta, who received a
$297-million contract in May 1989 to develop a vehicle by
1993. About the best thing which can be said for the FTS【M7】______
project was that it generated a lot of lessons learned. The
robot never flew and never will because it was never【M8】______
completed. This project demonstrated that fault tolerance
gone wildly will doom a robot. The robot had so many【M9】______
redundant systems that there was just so much to go wrong.【M10】______
【M5】
选项
答案
out—去掉out
解析
词汇错误。此处表示“机器人能绕过障碍物,穿越舷窗”,“穿越舷窗”包括进和出,而out只表示“出”,属于用词多余,故删。
