Hi Z. ,
This will only be possible with limitations.
Because you will have several errors every round, you will lose your track
after some rounds.
This errors are given from (for example)
1. not at once stopping motors when the given value for the rotation sensor is
given and the motor is turned off (especially on a skewed surface)
2. slipperage from the wheels
3. correcting for driving straight (when exactly driving straight or driving
with correction (in little curves exaggerated) you will have the same result
from your rotation sensors, but drove different distances)
4. possible reading errors from the rotation sensors
5. ....
6. ....
.
.
.
The only chance for my opinion is to create a "HOME" for your truck to redefine
its location on your track.
