Solar Powered Lego Roller

I bought a Lego solar panel to see what it could do. Not much really….

When I first saw the
Lego solar panel
in the Dacta catalog, I knew I would need
to buy one. I built a few experimental
chassis while searching for a configuration
that could be driven by the low output of
the solar panel. This one seemed to work best.

I used a power
switch to make the
robot go backwards or forwards, depending
on the switch position. This chassis is
is very slow, since I had to use a worm gear
to drive the wheels.
Here is the mpeg movie of the
roller using a lamp for the sun.
