Want to help out!? LEGO ROBOTS!

I needed a simple basic robot for my students to learn to program with, so here's the design I came up with.

Make a GREAT BIG MESS:



Sort parts into kits,



and BUILD BUILD BUILD!



I changed my simple sensor bar on the last one and have since converted them all over. The new version holds an ultrasonic sensor, light / color sensor, and a third motor that can act as an arm for lifting things.





Once I got it figured out, it took about 5 minutes to build each bot. Should be pretty easy to maintain. Still need to buy 5 more kits and build 7 more robots! Anyone want to put some money towards a good cause?

Here's the old ones we are replacing.

And donate to a great cause!  I've had some great donations already but still need $600 more.  You can try the promo code "spark" and it may double your donation, but I think its expired...

Thanks in advance for your help!
