Mecanum: VEX VS. AndyMark

[MJ Miller]

I have no experience with Vex mechs, but for AM I recommend the 6"Heavy Duty mechs. These cost $399 per set, have thick side plates, and No 10 screws with bronze bushings - very reliable. The cheaper ones have thin side plates prone to bending, and No 6 screws prone to breaking. I had many rollers come off on the field with the cheap ones. Also, I never have used the 8"and 10" wheels sizes due to weight. Regardless of the wheel size, roller performance is critical to proper drive function (along with wheel contact and balanced robot weight).
