LEGO NXT Money Counter

This is a nice project for the LEGO enthusiast.  You can check out the project and watch the You Tube video of the robot counting money.  Unfortunately, I did not see plans on how to build the robot on the The NXT Step blog.  It would be a fun build to try out.  Still, it is entertaining just to watch.

A nifty little money counter. It uses the size of each coin to determine it's value.
From the creator –

I made a little project with the aim to get an automatic money counting machine.
The Robot contains:
3 Motors
touch sensor
light sensor
The Robot decides which coin it has by the size of the coins, then he ads the values and displays the result.
When all coins are counted the robot recognizes this and gets itself back to starting position. ready for the next coins.
again its programmed with nxc , and took me 2 days. (works with euros and cents)
