They'll probably be fine....
They're using 8" skyways which have a pretty poor coefficient of friction. Less than 1, but for this example I'll just use 1.0 as a safety factor.
assuming the robot weighs 60 lbs fully loaded, it will take 60 in-lb per gearbox to slip the wheels.
Each gearbox puts out ~460 in-lb (the '07 FPs, I know they're all different... but in this example the margin is big enough).
So, at 60 in-lb, the FP will draw 8.3 amps... they'll be fine. but if we double it to 120 lbs, they'll draw 16.6... which is a little more iffy.
