This is a two motor walker. The surplus "1/3 RPM"
gearset is used, with CD Spindle Motors attached.

you see the front view, without the circuit board or batteries attached.
The rubber feet are for walking on carpet, works great! Normally my 'bots
can't walk on my carpet, this one does, but only with these 'boots' on.
Back feet just dig into the carpet nap and push ahead. Haven't tried the
backup circuit yet and may change how the back feet are shaped.
side view, with all attached. Batteries are under the back gearset, held
in with a rubber band.
side view, with all unattached. Rubber feet are on the front legs. The
clear LED on the (left side in picture) circuit board is for future IR
object detection. It is a 6000mcd RED-LED, can't look into this one, it's
that bright. It shines a moving spot out in front from it's 8 degree light
cone. It pulses about 3Hz. Credit for LED driver
and receiver goes to Wilf Rigter.
we go ! This one in action kinda looks like the Tilden Shok-Bot in movement.
There's a rubber boot around the RED-LED on the circuit board. Just inside
of that Boot is white heat shrink tubing to size the LED up to fit that
up of the front gearset. More details on the gears.html page (button above).
was to be the second frame in a "movie" from a Kodak DC260 camera. It was
going to do 3fps and did two shots then quit, bummer. You can see the RED-LED
on and one of the four red-led's that show the microcore state. The picture
is fuzzy because the 'bug is on the move and the camera does drop picture
quality while it's trying to capture the stills.
