Lego Robot Sends Pictures from Space, Wishes It Had Lasers to Annihilate Us All
Posted by Jesus Diaz at 4:59 AM on August 2, 2008
Last Tuesday, a group of professors, students and robotics hobbyists launched the H.A.L.E. (High Altitude Lego Extravaganza): seven Lego Mindstorms robots attached to a weather balloon, which exploded at 30km over the Earth's surface. Each of the robots parachuted back successfully, but not without taking the obligatory photographs of the ascent and descent:
The seven robots were designed to achieve seven different missions:
Brian Davis, Indiana, USA
Project: Little Joe
This robot will perform an automated free-fall in an attempt to set the record for the longest MINDSTORMS NXT free-fall. The robot will be detached from the main balloon near maximum altitude and will free-fall until the parachute deploys.Project: Gypsy
The robot will be an automated camera platform that will take both video and still images. The MINDSTORMS NXT will control all image timing as well as pitch angleFLL Team 90/David Levy (Coach), Virginia USA
Project: FLL Team Challenge: Climate Connections
A FIRST LEGO League Climate Connections team will build a robot to measure UV radiation as a function of altitude. The MINDSTORMS NXT will not only data log the UV sensor readings, but will also be used to rotate the UV filters in position as well as control the robot heater with a temperature sensor.Barbara Bratzel & Chris Rogers, Tufts University, Massachusetts, USA
Project: Fourth Graders
A group of 4th grade students will investigate the impact of flight conditions on yellow marshmallows (a.k.a peeps). The MINDSTORMS NXT will be recording temperature and pressure during the mission.David Martinez, Jurgen Leitner, Sweden
Project: SpaceMasters
The robot will be measuring the change in G-forces as a function of altitude. The robot will repeatedly drop a tethered Wiimote at different altitudes to measure the acceleration experience.Claude Baumann, Francis Massen, Jean Mootz, Luxembourg
Project : LUXPAK
The robot will be using an RCX to measure ozone concentration, air pressure, temperature (inside and outside) and reflected light from Earth during the descent.Eugene Tsai, Taiwan
The robot will be using filtering papers to capture particles and/or chemicals in the air during the balloon ascent and descent periods. The LEGO Mindstorms NXT will be used to provide a mechanism to switch filtering papers to capture the materials in the air and then keep the papers in a secured compartment. The filtering papers will be retrieved and analysed to see what chemicals and particles exist in different altitudes.

I'd love to see a "glider" made of legos launched this way. granted they'd have to be super glued together.
Also, what the hell, how could they not do this one:
Donnie Darko
Project : Poke the Hamster
The robot will be using a small lego stick to continuingly poke a hamster while it gains altitude until the hamster explodes. The purpose is to see how high you have to go before a biological animal explodes.

What I find amazing about these pics is the random framing. Picture from orbit are always perfectly composed: all in focus, subject framed properly. To have a pic with the immense earth stretching out below and a blurry rubber fragment in the foreground...I dunno, it makes outer space very real for me.

Does anyone wonder what the radiation up there did to the Lego's? Will they mutate?

We send legos to space for the first time and they don't send a Death Star or Millennium Falcon?

Oh god please tell me at least one of them was carrying a lego passenger. I salute that brave soldier.
I tried to send a minifig into space in my younger and more idealist years, by tying an enterprising your astronaut to a helium balloon and releasing him to the wild blue yonder. Sadly he was never seen again.
Just look how far we've come.

My dream would be to send a model rocket up on a balloon like this, with a minifig inside, and somehow have the engine lit just before the balloon burst.

This is exactly what we DON'T want our government doing. Sure, lasers are cool and all, but as Afghanistan and Iraq have shown, you can inflict severe casualties by simply throwing enough cheap and gullible lego men at the problem armed with ILDs (improvised lego devices) at our men.

@Git Em SteveDave is a poor substitute for LindsayJoy: I think they already have, you see, a short tie back, and many may remember, a large minifig washed ashore somewhere in Europe, I don't recall where, and I think this may be related to the Lego space program headed by mhlaxp, they didn't use adequate shielding.

@bpapa9013: I never said I wanted to achieve true orbit... :)
I imagine a weight-balanced platform, with the launch pad at one end, and a camera at the other end.
I would get one of those 3-stage model rockets with a transparent payload section, where the minifig would sit.
Who cares if the rocket is never found again, I would love to have the launch sequence photos!
And if the rocket IS found, then I'd arguably have the first ever minifig that earned its astronaut wings.

@wingbatwu: That actually is a pretty ingenious idea: attempt to launch something into a true orbit from 30km.
Would greatly cut down on the necessary transit fuel, but you still gotta get the appropriate velocity, which I doubt any sort of model rocket could achieve (not a rocket that is light enough to be carried 30km up by a weather balloon anyway). Not to mention the fact that dangling from beneath a weather balloon does not a stable launch pad make.
So, I like your idea, but the practicality of it is still somewhat lacking...

@wingbatwu: While I too think this is a fantastic idea I fear it wouldn't work. Probably not enough oxygen at that altitude for combustion of a standard model rocket engine. I don't think the Estes variety uses an oxygen-rich fuel component, but I could be wrong.
Now if you make your own engine, or use NO2+hydrocarbon like the mythbusters civil war rocket you probably have a shot.

@jtheletter: Wikipedia says that rocket motors above the E rating use a propellant similar to the one used in the space shuttle boosters, so I think an F motor would readily ignite.

Er, _most_ of them safely parachuted to ground as planned. Poor Little Joe, on the other hand, ended up with a tangled chute and landed the hard way. From 80,000 feet. Reportedly, the NXT was still intact and running the program when it was recovered, and all the related parts were unbroken as well, thanks to being encased in a large styrofoam shell.
If you've ever had a chance to meet Brian, that is one crazy guy. You can read his preliminary report on the results here.
@mhlaxp:
At least one of them was carrying a passenger. Brian's Gypsy had what appears to be an Alpha Team Crunch minifig dressed up in Brick Forge's new HALO...er, I mean Space Marine armor. Little Joe had the Alpha Team Flex minifig, sporting his original headgear. Personally, I think he should have gotten his hands on the official LEGO Dino Attack minifig w/ parachute and had it set up such that if the main chute failed to work properly, the NXT would automatically eject the passenger out the bottom.
@Lupison:
Doesn't work that way. "Explosive decompression" is a term that describes what happens when a habitable space is abruptly exposed to hard vacuum, not the urban myth of living creatures blowing up due to the lack of air pressure. You asphyxiate, the moisture boils off of your eyes and out of your mouth, and you might have ruptured capillaries in your skin, but that's about it. The hamster, on the other hand, would probably freeze to death before it would run out of oxygen.

I have been really wanting to do this. seems easy, just need the hardware. figure a good calculator ( i phone should do) , latex baloon to spec, helium, rig for snapping photos or shooting video, and a portable ham radio to track position and altitude using [www.aprs.net]
also can't forget about faa part 101 compliance for unmanned balloons.

Besides, what can they do? Suspend the pilot licence I don't have?

@Purple Dave: Challenge #1: Identify the offender.
It's unlikely they'd put the effort into a prosecution unless there were a problem caused to get thier attention. So few people would know that what you are doing is against the FARs that it would probably go unoticed and unreported to the FAA. They are a bit unobservant most of the time if you aren't actually on an airport or in controled airspace.

If by "suspend pilot's license" you actually mean "impose fines and jail time", then yes. They can.

@aeroworks: &balloondoggle: &Purple Dave: Easily solved by getting on a boat and heading out past the three (I think) mile zone (though many contend that you start measuring at the edge of the tectonic plate or some such oddity and others argue for a larger distance from shore). Once in International waters, you don't really have to comply with the FAA.
HOWEVER, compliance is a nice idea in this case because it will help make sure you don't cause an air-disaster of some sort.
As a kid, I had twice as much string as I needed for setting the kite altitude record. I had it all out, but the kite was out at a bad angle, so not really high enough. Then the police helicopter yelled at me to bring it down. Ahhhh.... The memories.

@balloondoggle:
That's easy. You just wait for him to land, like they did with that bozo who drifted through the airspace of LAX a number of years ago. Once they've spotted you, it's a simple matter to follow you, and it's not like you have much say in where you're headed beyond the ability to incrementally reduce your altitude (which might send you in a different direction based on prevailing winds).
@hnkelley:
It used to be three nautical miles in some countries (including the US), apparently because that's as far as you could lob a cannon ball to express your irritation at what the other guy was doing. UN law recognizes a generic limit for territorial waters at 12 nautical miles (almost 14 regular miles) from the low water mark, except where negotiated differently by treaty. So, if you want to head out 14 miles from shore, and hope and pray that you'll come down somewhere that your buddies on the boat can recover you, while _not_ passing back over the territorial waters boundary...well, I guess there's not much they can do to stop you. Technically, as long as your ship is flying a flag of registration, you're still subject to that nation's laws while on the high seas, but I guess once you leave the deck that jurisdiction no longer applies to you, and one could argue that no laws are broken until the very moment you cease to be within the localized jurisdiction provided by contact with the boat.
