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 software to control these devices. "They’re the best toys out there," says Howie Choset at CarnegieMellonUniversityinPittsburgh. Choset is a roboticist, a person 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 computer science in college. But when he got to graduate school at the California Institute of Technology inPasadena, Choset's labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move on 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. Choset's 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 don't , such as rolling. Choset's snake robots could crawl (爬行) through the grass, swim in a pond and even climb a flagpole.
But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient's chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?
Choset teamed up with Marco Zenati, a heart surgeon now atHarvardMedicalSchool, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and then tested the robot in pigs.
Even after 15 years of working with his team’s creations, "I still don’t get bored of watching the motion of my robots." Choset says.
The application of a thin robotic snake makes heart surgeries less time-consuming.
选项
A. Right
B. Wrong
C. Not mentioned
答案
C
解析
第五段只提到 Choset 设想他的机器蛇是否能运用于医疗领域,减少心脏手术的创伤面。并没有提到机器蛇可为心脏手术节省时间,所以本题答案应该选C。
