Lego Mindstorms In Space

It fits (whole) into a approx. 1'x1'x1' box and weighs less than 3 lbs. It's main mission is to collect small, flying debris. It can interact with the station walls and crew and supposedly has some light "mischief" programmed in as well (sneaking up on people, dancing). The story can be found here, de.news.yahoo.com, it's in German (sorry)." We mentioned the contest a few months ago. Altavista gives a semi-readable machine translation.
And to think that Halloween is just around the corner. If you have enough of them, do they try to "collect" larger floating particles [smile]?
Side Note, Intertran is also decent as an online translator.
and here's a nice list of various robot competitions

It seems to me that even mentioning babelfish is redundant these days. The people who don't know it exist tend not to be the slashdot type. But maybe I'm just being an elitist.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
If you have trouble with Alta Vista's translation, or just want an alternative translation, you might also try Google's Translation.
Sometimes it's best to just let stupid people be stupid.
Most of the fuel is not used for lift, but used to reach orbital velocity according to the formula:
E = 1/2 * m * v^2
joules = 1/2 * (0.0685*slug) * (1.60934/3.6*mph)^2
Slugs? Isn't that an archaic unit of measure? Surely you meant to ask for its mass in Newtons
Good Lord no. First of all, the SI until for mass is the (kilo)gram, the newton is a measure of weight. Second, the slug, which IIRC weighs one pound in earth gravity, is a perfectly acceptable unit of mass. At least, as acceptable as imperial units get
Stupid like a fox!
It's not perfect, but I do a far better job then Babelfish or Google. Still not quite sure what "impulseantrieb" means though. We'll go with "momentum drive." Some of the words that I wasn't sure of I've enclosed in ?question marks?.
Lego Robot "Jitter" Sweeps in the IIS Space Station
Konrad and Bastian Schwarzenbach have won the "Ultimate Builder Competition" from Lego Mindstorms with their model "Jitter." The small robot, made from Lego and Technic pieces will fly to the IIS Space Station in November.
Out of 124 participants in the "Lego Mindstorms goes Space" contest, the last ten met in Munich for the finals. In the presence of Jury Schirmherr and Astronaut Ulf Merbold, father and son were declared the winners. The winning model Jitter will gather pieces that are flying around in the IIS--at least it's programmed to do that along with other functions. A special prize went to the astronaut muscle trainer that a six-person team from Austria, Germany, and Switzerland had built.
With Jitter the crew will get a helper at hand that, if it keeps itself safe in weightlessness, gathers pieces floating around the space station. In addition, Jitter communicates its findings or contact with a cabin wall through tones and light signals. Jitter is based on the commercially available Lego Mindstorm pieces. Hitachi H8 Microcontrollers, which are off-the-shelf programmable chips, constitute the heart of the robot.
Jitter was programmed in Java (TinyVM) by Konrad Schwarzenback
When Jitter is turned on in zero gravity on the IIS, it must be brought to rest with the Z-axis pointing towards the Cabin lighting, which serves as a permanent guidance point. The robot will then perform a few 360 degree rolls to initialize its steering parameters, and can be brought on-line with a light push.
[The following paragraph is the most techical and worst translated. Sorry.]
Jitter works with a momentum drive. A cam disc ?rotates? permanently inside the robot's housing. When it comes in contact with a wall, the housing gets displaced. According to the direction of the collision, an impulse in the opposite direction is generated.
In addition, the robot is outfitted with light, touch, and rotation sensors that turn it and guide it on its course. Jitters mission is to gather floating pieces with a broom made of Lego-tubes and sweep them into its body. When Jitter hits a wall, the compartment closes automatically, so that the gathered pieces aren't scattered all over again. Jitter also reacts through the touch sensors to petting and patting and is programmed for all sorts of nonsense such as sneaking up and scaring someone, dancing, and prolonged rotations. In addition it reacts to ?wink motions? that it picks up with it's infrared sensors.
One of the tasks for the Mindstorm builders was to fit their robot in a 30x30x30 centimeter box. Jitter, in contrast to some of the entries, can be transported in the box in one piece. In addition the models could be no heavier than 1400 grams. For Bastian Schwarzenbach, who undertook the mechanical construction, this was the hardest task. He took Jitter apart and rebuilt it (differently) so many times, that by now he knows every piece by heart, he said during the prize presentation at Siemen's Munich ?Forum?. Both of the hobbyists will get to watch the start of their robot live in the Moscow control center.
