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 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 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
Califomia Institute of Technology in Pasadena, Choset's 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 bagan 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 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 called Medrobotics in Boston is
now adapting the technology to surgeries 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," Choset says.
1. Choset began to build robots in high
school.回答
2. Snake robots could move in only four
directions.回答
3. Choset didn't begin developing his own
snake robots until he started working at Carnegie Mellon.回答
4. Zenati tested the robot on people after
using it in pigs.回答
5. The robotic technology for surgeries on
people has brought a handsome profit to Medrobotics.回答
