TileRunner Chassis Hulk

The foundation of this drive base is a set of 0.090 inch thick aluminum components that provide a sturdy structure to build on. All of the holes in the sheet metal are on a global 16mm pattern, which integrates nicely with many structure components already on the market for FIRST Tech Challenge teams. The included plastic bellypan increases the rigidity of the frame and provides ample mounting options for your electronics. The TileRunner Hulk features high traction 4" Performance Wheels with Green Grippy Tread, NeveRest 40 motors and PicoBox Gearboxes with multiple gearing options. Strong 9mm HTD belts drive the outer wheels, while the center wheel on each side is direct-driven for a compact, failure-tolerant drive system. The new AndyMark Nub is used throughout the TileRunner, providing a robust D-bore interface that greatly improves torque transmission compared to standard set-screw hubs.

Note: This product ships as an unassembled kit of parts.

Gear Ratios
The kit comes with 3 different gear ratio options, so that you can experiment and understand how changing the gear ratio affects the driving performance of the TileRunner.

• 45 tooth and 35 tooth gear combination yields a 1:0.78 over drive
• Two 40 tooth gears yield a 1:1 ratio<
• 35 tooth and 45 tooth gear combination yields a 1:1.28 reductio

The lower the gear ratio, the faster the output speed. The higher the gear ratio, the lower the output speed but the higher the torque.
