Wide World of Robots
Engineers who build and program robots have fascinating jobs. These researchers tinker(修补)with ma-
chines in the lab and write computer software to control these devices."They're the best toys out there,"
says Howie 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 that moved一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,Choset’。labmates were working on
something even cooler than remotely controlled cars:robotic snakes.Some robots can move only forward,
hackward, 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 robot、also moved in ways that snakes usually don't,such as rolling.
Choset’s snake robots could crawl(爬行)through the grass,swini 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 at Harvard Medical School,to investigate the
idea.Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.
A company caikd Medrobotics in Boston is now adapting the technology for g urgerie9 on people-
Even after 15 years of working with his team’s creations,"I still don't get bored of watching the motion
of my robots,"Clioset says.
The application of a thin robotic snake makes heart surgeries less time-consuming.
