Good luck with that one.
A good radio is a part of the solution, the question is what makes a good radio.

Just to point out, obviously several companies sell the prequisite reverse polarity SMA connectorized, precabled, and ready to attach antennas typically found on WiFi hardware. I have quite the selection of them I use for network evaluation and wardriving.
Course the problem is that if you vertical mount an omni and the field AP is directly overhead, you're probably in the weakest lobe of the field strength.
Perhaps a biquad mounted flat on the top of the robot on a copper clad PCB, parallel to the surface of the field with the APs directly overhead might be an option.
