20 inch Nano Tubes work simultaneously as gearboxes and chassis structuring. The default ratio for Nano Tubes is a familiar standard ToughBox® ratio of 12.75:1, but has room for different ratios if additional gears are swapped out.

Two Shaft One Motor:

Two shaft one motor Nano Tubes are intended for a four-wheel-drive robot with two wheels powered and two wheels un-powered.

Two Shaft Two Motor:

Two shaft two motor Nano Tubes are intended as a four wheel drive robot with one motor paired with one gearbox and one wheel.

Three Shaft Two Motor:

Three shaft Nano Tubes are intended to be used as a complete drive module for the side of a 6-wheel-drive robot. The center shaft is slightly lower than the two outer shafts for better turning. These Nano Tubes have one of the end shafts powered via one motor while the center and remaining end shaft are both powered by the second motor.

Three Shaft Two Motor Fully Geared:

A fully geared Nano Tube while having the benefits of a drop-center shaft six-wheel-drive also shares the load amungs all three output shafts between both of the two motors.

Weight Reductions with Optional Parts:

Aluminum Large Output Gear can replace the standard steel 50 Tooth Large Output Gear.

Optional Encoder:

An optional Encoder Package can be purchased and added to this Toughbox. If you already have a US Digital Encoder to fit this Toughbox, this Encoder Mount Pad will help you mount the encoder to the Toughbox. Here is a guide for encoder installation and alignment.
- Gear Type: Spur gears, 20 dp, 14.5° pressure angle
- Input Gear: CIM Gear, 14 tooth, 0.315 in. bore w/ 2 mm keyway
- Large Cluster Gear: 50 tooth, 3/8 in. hex bore
- Large Output Gear: 50 tooth, 1/2 in. hex bore
- Material: 4140 steel, 6061 aluminum
- Output Shaft: 1/2 in. diameter, 4140 steel with 1/8 in. keyway
- Small Cluster Gear: 14 tooth, 3/8 in. hex bore

Nice Platform For Class Projects

I currently use the Nano Tube Chassis as the primary platform for all of the 'big' robotic projects in our robotics class. The pre-assembled platform allows my students to spend more time designing, researching, and building the other mechanisms associated with each assignment.

Demo Robot

From what I can garner so far, this system should work excellently for a compact demonstration build.
One Qualm: It comes pre-assembled :(

'4 Day Beta Bot'

'We set about creating a 4 day wonder for an off season event to introduce our new students to the FIRST experience. Key to the success of this project was the quick delivery and flawless performance of the Touhbox Nano Tube transmissions. As always, AM came through with flying colors. We couldn't have done it without them.'
