NXT Domino Robot
As his primary MDP project, Dave Astolfo decided to build a domino-laying robot. This robot is an NXT version of the RCX domino robot he previously built for the book "10 Cool Lego Mindstorms Ultimate Builders Projects". You can see it in action here.

Dave also published the NXT software he wrote. You can see that even a robot performing a real function doesn't require complex software.

The domino robot is also an interesting demonstration of how robots are different using Lego Mindstorms NXT. You can see earlier versions created using Lego Mindstorms RIS (RCX) here and here. According to Dave, the new NXT version is faster and more agile than the older RCX versions. I think the new design also looks "cleaner".
The NXT version takes advantage of the wheel encoding to position the domino correctly, by driving backward by the amount it drove forward, minus 70 degrees. That's all that is needed to put the domino within range of the previous domino.
I can't wait to see the version that uses an extra motor to avoid driving back and forth, and follows a curved line.

that soo cool... but are all those pieces from the mindstorms NXT or also from the RCX.
I'm not sure if all parts are from the NXT box, there may be other Lego Technic parts used. But I don't think any RCX parts were used.
Hello Mr Astolfo,
I was just wondering if you could send me the instructions on how to make this fascinating robot. I wish i could make something like that. If you can, could you please send it to my email: liang_qu_96@hotmail.com. Thanks!!!

that is so cool please post the instructions on how to build it
Hey Mr. Astolfo,
I was wondering if you could make online instructions for the newest version of the domino-placing robot. Thanks!
