Wide World of Robots

Engineers who build and program robots have fasCinating jobs. These researChers tinker(修补) with maChines in the lab and write Computer sdftware 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 who designs, builds or programs robots.

When Choset was a kid, he was interested in anything thatmoved--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 Computer sCienCe in College. But when he got to graduate sChool at the California 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 ) in many direCtions and travel over a lot of different types of terrain (地形). Snakes are far more interesting than the Cars, Choset ConCluded.

After he started working at Carnegie Mellon, Choset and his Colleagues there began developing their own snake robots. Chosets team programmed robots to perform the same movements as real snakes, suCh as sliding and inChing forward. The robots also moved in ways that snakes usually dont, suCh as rolling. Chosets snake robots Could Crawl (爬行) through the grass, swim in a pond and even Climb a flagpole.
