I knew that one of the big problems with the tracked vehicle is severe 
slippage especially during the turning. I do not have any experience 
with tracked vehicle, I have several questions and like to hear from 
knownledgable netters:

1. If I instruct a tracked vehicle to turn 90 degrees, what kind error 
in orientation I should expect? say on concrete floor? 5 degrees, 10 degrees 
or more ? In other words, is dead reckoning still a feasible option for 
navigation? 

2. Is this error consistent or more random in nature? Seems to me it is 
random.
