Initial tests and notes:

            Current "Vexter Drive":  Mecanum drive 1:1.6 ratio, HS motors set to speed setting.
            Back drive pods are on a joint for movement over obstacles
            Current "Vexter Drive" height:  0.8 in

            Spacing between the front and back pods:  3.3 in

            Sack Specs:
                     Sack not fully flattened: about 2 in
                     Sack on Side:  about 3 in

Tests

                                     Driving over one sack:

                                  Overall success, sack caught on back drive pod.

                                  Trying to push 5 sacks:

                                   Result: Failure 2.5 lbs of sacks cannot be pushed by this drive (yet)

                                 Trying to Drive over 5 sacks:

                        

                                  Overall success, able to move around sacks it was stuck on.

Final Thoughts

Drive has great maneuverability

Able to drive over some sacks 

Able to translate over sacks in the center of drive

Unable to push more than 2 sacks

May need to lower wheels in drive pods to increase clearance

Sacks are definitely a field obstacle
