This is the "AM" - "ONE" - "FOR" - "YOU"!
Perfect for prototyping robotic applications as well as being part of the final design! This large format, infinitely configurable drive platform was designed to be built with performance in mind. The AM14U5 drive chassis has three main configurations (Long, Square & Wide) as starting options. The drop center wheel allows for smoother turning ability, while maintaining stability.
What Can You Do?
Want to learn what you can change and accomplish with the AM14U5? Start here for a look at all the things this frame can do for you.
This is the 5th major upgrade to this popular chassis with many more minor revisions. Our AM14U family of products has evolved and changed based on customer feedback since the first AM14U was released in 2014, and it was a major upgrade to the C-base chassis that was part of the FIRST Kit of Parts since 2009.
This product ships as an un-assembled kit. It features HiGrip Wheels, Toughbox Mini Gearboxes, and Gates HTD Belts.
Assembly and cutting of aluminum is required. See the Assembly Videos below.
If this chassis is being used for the FIRST Robotics Competition, please consider the robot perimeter rules and size this chassis accordingly. The manual helps clearly show where to make cuts for different sizes, you can adapt your cuts to fit as needed.
NOTE: This chassis DOES NOT include the following as there are many options for each case:
- CIM motors (am-0255) or NEO Motors (am-4258)
- Bumper Hardware Mount Kit (am-3966)
- Vertical Battery Mount Kit (am-3964a)Recommended method for Battery mounting to this chassis.
Various Frame Size Configurations:
Built on the same great features of previous AM14U family chassis, this can be configured into many different perimeter, wheel, and gearbox configurations. There are literally thousands of possible playing configurations.
- Smallest Frame size: 24.3 in. x 27 in.
- Largest Frame size: 32.3 in. x 31 in.
It is shipped as a Kit with plates that can build in a large square configuration. This makes it the largest possible size and allows for the user to trim the length and width of the chassis to become a long, wide, or a smaller square to fit different the size constraints of each specific year. The assembly instructions show how it can be changed, be sure to check out the assembly videos as well.
Multiple Wheel And Build Configuration Options:
For even more wheel and build configurations, check out our AM14U4 & AM14U5 Wheel Upgrades!
The AM14U5 does not include encoders. The Toughbox Mini gearboxes included in the AM14U5 ship with an output shaft (am-2566b) that has two holes in the end for optional included 1/4" diameter steel dowels (am-1323) that are compatible with the US Digital E4T Encoder (am-3132) and the REV Through Bore Encoder (am-4650). Teams also have the option of purchasing a magnetic dowel (am-3505) to replace the steel dowel allowing the use of the SRX Magnetic Encoder (am-3445). In order to use this encoder on the Toughbox Mini, our SRX Magnetic Encoder Mounting Hardware Kit (am-3565) must also be used to mount each encoder.

To control this drive, you will need a power and control system like the Electronic Bundles kit, roboRIO, Spark Max, 4 CIM motors, and PDP (BCRX4CP). Many options are available!
The chassis requires a minimum of two CIM style motors (am-0255), but we recommend four CIMs to be competitive in situations like heavy robots, high traction, and pushing match situations that put a lot of load on the motors. You will also need at least one battery. We recommend the 2 Pack of Interstate Batteries (am-3062), and the 3 Bank 6 Amp Dual Pro RS3 Charger (am-2026). There are many options available here as well, take your pick!
Center Pulley Screws:
Fear not friends with robots! The 2022 Kit of Parts Chassis was identified to have screws that backed out on the center pulleys. These screws were replaced with screws that performed as intended. AndyMark evaluated and implemented those replacement screws in full for the 2023 Kit of Parts Chassis. You may find that the screws look similar, but rest assured, these pulley screws will not cause you this alarm.
