[Mattias] brings the awesome once more with his LEGO robot that sets up dominoes. You’ll remember his work from the wooden keyboard case and the mechanical binary adder. This time around he’s still exercising those woodworking skills by making his own domino tiles, but it’s the robot that makes this interesting. In the must-see video after the break the device lays perfectly straight, perfectly spaced dominoes just begging to be upset by a spoiled toddler. The robot is nothing more than handful of LEGO parts powered by a tape deck motor. The parts may be meager, but there’s an abundance of ingenuity tied up in the design.

step 2 now should be to make it be able to lay in different patterns and a larger storage capacity :D
man thats awesome
Add a uC and bluetooth and control it with wiimote/iphone/younameit
Nice writeup and build. Add a bigger hopper and use an IR sensor to find the table edge and turn automatically. Then, let them loose in parks and cities.
Next, build a robot that picks up the fallen legos and puts them in the first robot.
file this under great stuff lego can do that you never did when you had them.
store them turned 90* and rotate them into place, like a P90 does :P
setup for a second shelf of dominoes with a worm/reduction gearing to pull the shelf bottom out to reload, timed for when the last couple are about to leave the pusher.
Yeah, if we had the retrieval-reloader built we would have the compiler needed to build a domino computer.
BTW, I will build one of these with my nearly-3 year old when he’s ready. Great post Hackaday.
HAX!
Nice ingenuity with such simple everyday parts!
Good job Mattias!
Ah yes.. saw this the other day. Most definitely sweet. I would’ve killed to have one of these as a kid.. ;)
That is so cool.
This has been done so many times before. For proof, search youtube. I, in fact, have one sitting right next to me right now.
op well done, it looks cool. Now all we need is a model that resets itself to the next row and can take massive numbers of dominos
This brings back memories. :)
I remember getting something similar for Christmas one year. It stored the plastic pieces in a vertical magazine and dropped and aligned them as you slowly pulled the machine backwards. It was filled with a bunch of plastic gears that did everything (no electronics or motors).
Nice project, the only thing I can’t quite tell is how the domino supply automatically moves down the magazine. Any help?
Cyphus, he says it in the video. The friction from the table surface keeps the dominos toward the back of the machine as it rolls forward.
Brilliant.
it’s an automaton not a robot
