So here we have the MRL, built by me a couple nights ago and built by a bunch of little
kids yesterday at the little activity session.
I built this at night, so this is my first chance to test it out and see if it works
in the sun.
I'm holding the wheel with my finger, here. I'll release it. It's spinning. We have a
solar panel, here, connected to a DC motor.
Drive gear, here, connected to a gear on the rear axle. And then we're spinning rear-wheel
drive.
So, then, I'll place it down on the ground and off we go.
And, of course, it stops in the shade.
