Twelve-year-old maker Quin already has a company of his own–Qtechknow. He founded a hackerspace in his garage on California’s Central Coast. He helps teach Arduino classes for kids and adults. And he developed the “gas cap,” a baseball hat that detects human methane emissions. (What 12-year-old wouldn’t want that?) And now he’s created the FuzzBot, a cool little robot that not only turns on a dime to avoid obstacles, it helps his mom out by dragging a dust cloth as it makes its rounds.
Last night, I watched a live feed from a command center in Pasadena, California, piped through the Internet 1800 miles to me in St. Louis, Missouri. I heard telemetry and ‘heart-beat’ confirmation tones from a 2.5 billion dollar Mini Cooper sized science lab (the largest ever for a mission) launched 253 days ago, from 353 million miles away, above the surface of another planet. That science lab hit the Martian atmosphere at 13,200 miles per hour. It burned through the atmosphere, and expended a 15 foot diameter heat shield (the largest ever for a mission) that had withstood temperatures of 3,500 degrees Fahrenheit (hot enough to melt every metal you can think of). It rode down on a 51 foot diameter parachute (the largest ever for a mission) designed to withstand speeds of 1450 miles per hour (there was no backup chute). Then the chute was abandoned, and the craft went into free fall for a few seconds. A rocket pack was activated to allow the car sized object to hover over the surface, while a skycrane lowered the entire thing gently to the rocky soil. It landed within a 12 mile by 4 mile ellipse, or around 38 square miles (the size of Barcelona, Spain*), within planetary spitting distance of a 3.5 mile high mountain.
All with zero command input from any human being watching, running on less computing power than the phone in your pocket.
*So take a sheet of paper, fold it in half longways. Now walk about 5,600 miles away. Now hit it with a bullet the width of a strand of DNA (~4 nanometers). That’s what it’s like to land the rover in such a small area from such a long distance.
I know this is a little late to the game but this is the best description of the Curiosity Rover success that I have read.
Easton LaChapelle is now a Junior in high school, he made his first robotic hand, controlled remotely by a glove with sensors sewn into it, won him 3rd place in the Colorado state science fair as a freshman, which reserved him a seat at the national fair in Los Angeles as an observer. This also won him some nice coverage in Popular Mechanics…
