This is amazing. I love LEGOS :D . I need to make one of these.

Re: Seriously long Lego system.
 

Looks like a cool, micro-sized way to test out some physics.

Re: Seriously long Lego system.
 

No, I can not take any credit for this. My son posted a link to it on Facebook. I just knew the folks here on CD would appreciate it.

Exactly what I thought as well.

What a wonderful prototyping system. :)

Re: Seriously long Lego system.
 

This is so cool. I wish I had one of these.

Re: Seriously long Lego system.
 

There are so many interesting concepts in that video. We now have no excuse to have a poor implementation the next time the GDC makes a ball-shooting game.

This guy (or girl...) must have timed the battery lives quite well too. Then again, nothing in the video looks like it'd overly stress a battery anyways.

My fiancee will be happy that I may no longer want a "LEGO room" in our metaphorical mansion of the future...

I think i still have mine in my basement. I used to play with them for hours and hours!

Re: Seriously long Lego system.
 

Simply Amazing!
I wonder how many Legos it took to build that?

Re: Seriously long Lego system.
 

This August we'll be staging a GBC at Brickfair in the Dulles convention center. Stop by. Plunk down a few bucks and be amazed at Lego construction in person. You'll need to add an entire metaphorical floor to your mansion afterwards.

Hard to believe that he did all of that on no more than one NXT controller;)

Re: Seriously long Lego system.
 

I count at least 3, (from a quick glance)

The line following truck, the claw at the beginning, and the ball-sorter.

I was trying to be sarcastic and make a little joke about the minibot rules for this year. Hence the wink emote.

Re: Seriously long Lego system.
 

Ah, sorry. It was a long day...

Re: Seriously long Lego system.
 

We're all entitled to a brain lapse here and there. I get a few more than most.

Re: Seriously long Lego system.
 

Thanks for the great remarks. The Great Ball Contraption was conceived in Indiana back in early 2005 as a collaborative project because several of us Mindstorms geeks were tired of simply competing with each other and we wanted to work together. We debuted the first GBC at Brickfest (Washington DC) in August 2005 with about 40 working modules.

Why do all the modules seem to work well with a process flow? We actually wrote a specification for the collaborative project. You can find the requirements at http://www.teamhassenplug.org/GBC/ if you want to try your hand at it.

GBC collaborations still happen at Brickworld (Chicago - June) and BrickFair (DC - August). They are mesmerizing to little kids.

Of course, those of us that started GBC have moved on to other challenges like Monster Chess http://www.teamhassenplug.org/monsterchess/ that debuted at Brickworld in 2010. We will have Monster Chess on display at the event in Saint Louis next week. Stop in in your "spare" time and see it run.

GBC was a lot of fun and you learned quite a bit about the durability of plastic along the way :)

Re: Seriously long Lego system.
 

And apparently those that are little kids at heart. Watching this reminded me a lot of watching videos of egg collecting and sorting factories. Very neat. After the ball sorter of 2006, and the issues of 2009, I have a feeling we may need to review this video after kick-off 2012...
