Any suggestions for how to improve my plan?
b) it's difficult to implement in a small memory space (though it can be done, according to different papers I have seen)
cr0sh, do you have some pointers to these papers ?
Am i right in thinking you provide your bot with a map
tell it to go somewhere & it finds the best or most efficient route to get there ?
Is there a rule as to what is constituted as a boundary?
A car type bot, has a fixed body shape and perimeter (fixed length) from the centre it is possible to be positioned in any direction, therefore we ascertain the cars total perimitary circumference.As we all know, not every surface is flat. A mercury type level (bubble) sensor, faceted with multiple switch combinations could be used relatively cheaply to provide input for the vehicles current inclination.
