    Every year landslides (山崩) cause 25 to 50 deaths and $2 billion in damage in the United States. And in

December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize (加固)

mountainsides using steel bars (钢筋) can help a lot, but it introduces new difficulties because of dust and

loosen heavy, dangerous debris (岩屑) from the work. "It's a quite dangerous job," says Giorgio Pezzuto of

D' Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called

Roboclimber.

    "The idea is to operate a machine far away that can do the stabilizing job without a human being near,"

says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that

the machine will be faster and cheaper than manual labor (人工). The robot, a large radio-controlled four-

legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill (钻) holes

and insert (插入) steel bars there. Testing should begin in May.
