It isn't! That's the real challenge!! :-)

I don't know if you intend to use the standard firmware, but in the CyberMaster I don't even have that choice.
The CyberMaster and the PC were made to work as one. For one thing, without floating point numbers, sin/cos functions or some sort of lookup table (which is also impossible), is not possible to make out anything useful out of the tacho readings.
My intent was NOT to make the CyberMaster work as a radio controlled car, was only to use the PC to help the unit.

If you call to use the Tachos cheating (which sounded like when you said one can't use the PC), then markings on the floor, using colored cans and colored walls, homing beacons and the light sensor is what!?
Seems to me that is more difficult to implement an efficient mapping system and make it cooperate with the unit than these "cheats" all together...
