11.   Space shuttle Endeavour will spend at least one extra day at the international space station after downed computers delayed tests of a new robot arm.

12.   That arm will be used Sunday to hoist the new larger robot arm to the laboratory.

13.   The new robot will be armored and will push a roller designed to explode the mines, the radio said.

14.   The new robots often are the whimsical spinoffs of research projects aimed at more serious applications.

15.   The new Boa robot uses a water blast that is strong enough to strip paint from a car to cut chalky asbestos into baseball-sized chunks.

16.   The new robot arm is needed when the next space shuttle arrives in June with another space station chamber.

17.   They set up the Destiny laboratory, outfitted a new air lock and fine-tuned the new robot arm.
