Re: AM14U3 chassis with mecanum wheels?

Does the AM14U3 have the relevant holes to be used with any of these?

Basically, what pieces/parts did you use and how much modification was required?

Thanks!
Hello there,

The AM14U3 was actually designed with the AndyMark Toughbox Micro in mind. It was designed to work with 4" and 6" mecanum wheels without the need of serious modification. With 8" wheels, a small notch in the End Plates may be required to prevent a significant pinch point.

To use mecanum wheels on this chassis, you would use a Toughbox Micro with the output shaft from the Toughbox Mini that was designed for the AM14U. This is the shaft that ships with the Toughbox Micro when you choose the 'No Plate' option on the Toughbox Micro product page. 6 and 8" wheels are to be installed on the output shaft of the gearbox. To use 4" wheels, you actually run a short 1:1 gear stage with two 50T 20DP gears between the output shaft of the gearbox and the 4" wheel hole in Long Configuration of the AM14U3 chassis. I've attached a couple of pictures that show these examples.

Hope this helps!

-Nick
