FIRST Tech Challenge Chassis
TileRunner, TreadRunner and MecanAM
Five main configurations make up the base for the robot you need.The original TileRunner 6-wheel drop center or 4-wheel drive (mecanum or traction + omni), the TreadRunner (tank treads), and the MecanAM Chassis.
- Need a balanced drive train that can turn on a dime? Take a look at the 6-wheel drive TileRunner.
- Want to use one end of your robot as the center of rotation to help with alignment? Choose a traction + omni options on either a TileRunner.
- Precision movements in all directions part of your game plan? Mecanum variations allow for omnidirectional movement of your robot. Use this in either TileRunner.
- Need to get up and over obstacles? TreadRunner variants can overcome those pesky hurdles by stepping over or crawling through.
- The MecanAM Chassis has omnidirectional movement capabilities that can help drivers smoothly avoid obstacles and quickly change drive direction.

No matter which drivetrain you select, rest assured we've considered all the pieces and parts you'll need for the build. You'll only need some tools and your favorite workspace. If you already have many of the components that make up a TileRunner we have options above as well for no motors and/or no plates and/or no wheels!

TileRunner 6-Wheel Drive
The original six-wheel drop-center chassis for competing in FIRST Tech Challenge. This chassis has been used to great success by countless teams. Holes for upper structure mounting along the top of the drive rails.
Gearbox Support:
- NeveRests 14:1, 20:1, 40:1, 60:1
- Orbital and Classic PicoBoxes both single and dual motor.
Ground Clearance:
- 0.5 in. from wheel to belly pan hardware
- 0.6 in. from ground to the belly pan
Wheel Options:
- 6 Stealth Wheels
- 50A, 60A, 80A Durometer
- Stealth wheels provide a good amount of traction on soft tiles, the lower the durometer number the softer and grippier the wheel, but the faster it wears.
- 4 Omni, 2 Traction Center
- 50A, 60A, 80A Durometer Stealth Center
- Performance with Grey Grippy Tread Center
- Aluminium wheels with replicable tread material
- 6 Compliant Wheels
- 50A, 60A Durometer
- compliant wheels conform around to obstacles and act like airless pneumatic tires.
- 50A, 60A Durometer
TileRunner 6-Wheel Recommendations
- BT6S841 - This cost-effective 6-wheel drop-center drive TileRunner is where it all started. Good speed, turning, and power wrapped in an aluminum package.
- BT6O62A - The 6-wheel drive TileRunner BUT with high speed 20 to 1 NeveRests and grippier stealth wheels PLUS Omni wheels in the corners. This is FAST and can turn on a dime!

Push it to the Limit:
Ratios and SPEED
For these chassis, you can pick a NeveRest Ratio and Picobox Ratio. The combinations of gearing give you a plethora of drive speeds options.
NeveRests come in these ratios 60:1, 40:1, 20:1, and 14:1.
PicoBoxes come in, 7:9, 1:1, 9:7
All of these combinations give the following speed ranges for a TileRunner.
TreadRunners use only 60:1 and 40:1 NeveRests, but still, use all PicoBox gearing for the following speeds.
