The biggest problem with tank like drives is the marks/scratches on
the floor. Any robot with any weight will probably damage a maple or
other hardwood floor in short order. They work fin in a lab with
waxed tile floors that no one cares about, but in the real world, this
isn't the solution.
It sounds like everyone tries to rely on inertial navigation systems.
This is fine, and has worked for many missions for many years (space
explorations, aircraft navigation), but is usually used for gross
navigation (get you in the neighboorhood of the destination). Robots
need sensors to get fine navigation down. I would hardly enjoy a
flight to europe relying soley on inertial navigation, and landing
only 50 feet from the runway :-).
The handy board has IR sensors, use them for position sensing. Put
beacons in strategic locations within the space, and the kinematics
will work out.

| OK, time for me to chime in on this thread... The biggest problem, IMHO, with using a cheap RC car/van/truck as a 'bot base is that they all use Ackerman steering (two non-steerable driven wheels in the back, two linked, steerable, non-driven wheels (...)
