Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings: the restaurant industry. Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California. A team from South Korea and its robot,called DRC-Hubo,won the first place in the competition. The second and third place winners were from the United States. The robots were required to drive a vehicle,climb up steps and do mechanical work. Such activities are easy for humans to perform,but more difficult for machines. Not all of the competitor were successful. The failures showed how difficult it is to design effective walking machines. Akihiro Suzuki works at Yaskawa Electric,a company that develops robots. He says robots cannot do everything a human can,but they are able to work without becoming tired. He says robots cannot taste food,change heating levels or seasonings to get the best flavor .But he says if a food can be easily prepared,a robot can repeat the same movement to reproduce the same meal. One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery showed its sushi maker robot. It performs the often difficult work of wrapping the popular Japanese food. Hiroshi Monden is an official with the company. He says people all over the world now eat sushi,but there are not enough skilled workers to prepare it. He says his machine can help anyone make sushi.

If an earthquake happens, it may cause many deaths and injuries and great damage. Decide how and where your family will get together if separated. Choose an out-of-state friend or that the family members can call after the quake to report where they are and how they are. Know the safe place in each room: under the strong tables, desks, or against inside walls. Keep enough food, water and other things, including a flashlight, a radio, medicines and clothing. During the earthquake, you should keep a clear head and never be too nervous to know what to do. Protect your head and neck with your arms. If possible, take a book, a pillow or any other things to protect yourself from falling glass and ruins. If you are indoors, you must immediately lie under any strong furniture. If outdoors, move to an open area away from trees, buildings, walls and power poles. If you are in a narrow valley, move to the centre of it and look out for falling stones. If you are in a car, move to the side of the road and stop the car. Do not stop near buildings, power lines or under bridges. Stay in your car until the shaking stops. Do not move a badly injured person unless he is in great danger after the earthquake. Do not use the telephone immediately unless there is a serious injury or fire. Turn on your radio for instructions and news report. Be prepared for aftershocks. If you want to leave your home, post a message inside your home telling family members where you can be found.
