meet camille and genevieve beatty, who at 13 and 11 are being hailed for building a functioning scale model of the mars rover that is now a permanent ¹ at the famed new york hall of science.

美国北卡罗莱纳州的一对小姐妹自己动手，制作出能够实际运转的火星探测器模型。如今，该模型已经成为纽约科学馆的永久藏品。

the beatty rover is a near ² of the early version nasa sent to mars in 2004 and was unveiled in early august with hoopla（喧闹） that's made the red-headed north carolina ³ science rock stars.

"to have two young girls building our mars rover is exactly the kind of thing we want to have happen here," said margaret honey, president and ceo of the science center that sits on the grounds of the 1964 worlds fair in flushing meadows-corona park in the ⁴ of queens.

the girls' drive to build their rover was inspired by a documentary on the robotic exploration of the red planet.

but their love of science all started with a little "destructive curiosity," says their father, robert beatty, who guided their enthusiasm for engineering.

"camille kept taking things apart. she would bring me a ⁵ remote-control box or a dismantled clock, and she'd say, ‘dad, what's this little green thing in here.'"

he didn't have all the answers, but he was ⁶ by her curiosity and asked if she wanted to build something herself.

you bet they did.

from remote controls . . . to robots

then life in the beatty household started to get interesting. the sisters went from taking things apart to putting things together.

"we would just experiment," said camille. "we started small, using off-the-shelf radioshack parts. then we ⁷ let's go huge with it . . . and build a robot!"

over the course of two years, the beatty family built several robots — ones that could roll, crawl and even fly.

the family also built a website chronicling the girls' robot-making adventures. ⁸ meant to keep family and friends up to date on various projects, the beatty robotics site quickly gained a following.

from north carolina . . . to the big apple

even the folks at the new york hall of science were impressed. they were already planning to redo the mars exhibit when they decided to commission the girls and their dad.

"we didn't set out to look for two girls to build our mars rover. we were actually looking for companies that had robotics expertise," said honey.

the beatty girls' mars rover isn't a toy or a model. it's a ⁹ working version with more than 750 parts, many of them built by the family from scratch. it has rotating wheels and ¹⁰ that keep it from bumping into walls. it also has a ¹¹ suspension system that allows it to grapple with rough ¹².

"we studied the actual rover very closely," their father said. "the pictures, the drawings. ... we did everything we could to ¹³ it in every way."
