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.




PLEASE HELP ME OUT!!!  Share this page, or this link:  http://www.donorschoose.org/project/welcome-to-the-next-level-ev3-lego-robo/1747807/?rf=link-siteshare-2015-10-teacher-teacher_2238585&challengeid=373576

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!

Lego Engines!

Try this on for size! This was built by one of my 7th grade students. It's powered by a Lego Mindstorms NXT and actually runs pretty darn smoothley!



Square piston and crankshaft.



Interesting spoked flywheel and the "electric start".



Intake / exhaust port at the bottom of the cylinder.



Video of it in action!



He said he just kinda started putting stuff together and this is what came out of it. Very impressive!


Now, I could have sworn I posted this one somewhere but can't seem to find it... So here it is (again?).

This was built by one of my 8th grade students that was also building my wobbler air engine.  Same story- he was playing with legos and this sort of emerged from the chaos.  This one even RUNS on compressed air.  It takes a LOT of it though-  lots of leaks through all the gaps.







Kind of hard to see but if you look to the right of the little square lego piece you can see the air intake port.



And of course a video of it in action!
