3、tsEngineers who build and program robots have fascinating jobs. These researchers tinker (修補(bǔ)) with machines in the lab and write computer software to control these devices. Theyre the best toys out there, says Howle Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person

4、 who designs, builds or programs robots.When Choset was a kid, he was interested in anything that moved-cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in high school, he built mobile robots similar to small cars.Hoping to continue working on robots, he studied compu

5、ter science in college. But when he got to graduate school at the Califomia Institute of Technology in Pasadena, Chosets labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist (扭曲
