Product Overview

The AM14U4 is the most versatile chassis for FIRST Robotics Competition teams. The chassis was named as such because there is a flavor of this AndyMark chassis for every one of you. The fourth generation of the AM14U has an option that works for every robot need. All of the options available through this page include the upgrade components only and will not ship with an AM14U4 chassis.

Drive Style Options:

  • 6 Wheel Drop Center
  • 8 Wheel Drop Center
  • 4 Wheel, Mecanum

The AM14U4 ship's standard with a 6 wheel drop center drive. The center wheels are dropped to improve turning capabilities. An 8 wheel drive style can be used as well allowing for more points of contact with the playing field. The center four wheels are dropped to decrease turning scrub. If you are interested in omnidirectional drive the U4 will support a four-wheel drive for Mecanum.

Wheel Type:

  • HD Mecanum, rigid small profile mecanum wheels for precise driving in all directions.
  • SR Mecanum, incredibly smooth-rolling mecanum wheels.
  • MK Mecanum, large and high capacity mecanum wheels.
  • Performance, high strength high load capacity metal wheels to be used with 1 in. wide replaceable tread.
  • XL Performance, the same perks of Performance, but wider! These performance wheels are 0.5 in. wider than regular.
  • DuraOmni, these omni wheels can be used in the corners of a U4 to create a rapid turning machine with virtually no scrub.
  • Pneumatic SD, plastic hubbed wheels with inflated inner tubes to create a squishy grippy drive.
  • Pneumatic HD, metal hubbed wheels with inflated inner tubes. A squishy grippy drive with an unbreakable hub.
  • HiGrip, plastic wheels with a strong polycarbonate center and a grippy TPU outside.

Wheel Diameter:

  • 4 inch
  • 6 inch
  • 8 inch

Larger wheels move your machine around the ground faster and require lower reduction gearboxes to move them. Small wheels require a larger reduction from your motors to hit the same speeds as big wheels, but take up less space and allow for more wheels.

Changes Beyond Bundles:
While we only list sixteen different upgrade kits here, you can further tweak these options by trying different types of tread on performance wheels, different durometers and diameters of HiGrip wheels, or adjusting the ratio in your gearboxes. If you don't see an option you like or want help configuring an option, contact us and we can help you find the right one.

Individual Components within Upgrade Kits:
Each of the upgrade options we offer includes the components and hardware needed to add the desired wheels and arrangement to the AM14U4. Details of what goes in each upgrade kit can be found below.
