Aaaand the B-robot EVO off-road version is here.
It has been easy to modify the original B-robot EVO adding new Off-road wheels (regular 83 mm diameter RC buggy wheels, quite easy to get and inexpensive). If you already have a B-robot, just modified the parameters indicated below in its code or upload this slightly modified CODE version to the Arduino: BROBOT OFFROAD
NOTE: We have used these NUTs to fix the wheels (working nicely so far)
