Good, the mowbots have moved on to carrying little pilots who
jump out at opportune times to clean the sensor windows, anyways
:).

The local Barnes&Noble has taken to carrying a number of robotics
books, and Jones/Flynn is one of them. Most of the books are pretty
low-level in the sense that they concentrate on the mechanical
end of things, but J/F gives good coverage of all aspects, and
esp good coverage of programming/subsumption. They have multiple
examples of how to setup bots for different tasks. Subsumption
can result in some pretty interesting "emergent" behavior.

Hmmmm, 6"x9"sounds a little large for operation off the Tamiya
dual-motor - obviously something that big is gonna lend itself
to loading on all kinds of sensors/etc. I designed up a little
4"x4" sumo-sized bot made out of lego blocks for the tamiyas.
Who says you can't get something for nuttin.

That was before I got the tank. Also, since I put up the pics,
I found some runners for an aluminum sliding door to use for
front-axle casters - so the front axle is a wee bit slicker.

I also plan sometime down the road for a bot of your size, but
plan to use a couple of the cool 12v gearmotors sold by Jameco,
which come is all kinds of gearing ratios, plus 12v SLA for power.

Far out, CCD + Xmtr for $79.

Oh gosh, a spy.
