Re: pic: Cheap 6WD
It is not completely clear from the CAD, but remember that:
1) The middle wheels need to be offset lower, or the robot won't be able to turn easily. We are using a .5 cm offset this year, but I have read about teams using 1/8 inch.
2) Many teams use omni wheels on one or both ends (not the middle) to aid in turning. The omnis compromise pushing power a bit, but make turning much easier.
