Every year landslides 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 mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris 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. 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 holes and insert steel bars there. Testing should begin in May.

E—schoolbags
Is your schoolbag too heavy to carry? The e-schoolbag will help you. It is said that e-schoolbags are going to be brought into use in Chinese middle schools soon.
Heavy schoolbags have been a serious problem for a long time. But the e-schoolbag will work it out. An e-schoolbag is much lighter than a usual schoolbag. Perhaps, the e-schoolbag should be called an e-textbook. It is as small as a usual book, but it can still have all the things for study, such as a textbook, an exercise book and so on. They can be made into chips(芯片) like stamps. The students can read the text page by page on the screen, take notes, or even send e-mails to their teachers. They only need to put the right chip into the e-schoolbag and then the students can use it.
