TileRunner Chassis BullDozer Option

When you want to push, pick this! NeveRest Classic 60 gearmotors (am-3103) provide maximum torque, while six of our softest compound blue 4" Stealth Wheels (am-2648_Blue) put that to the ground for maximum pushing force. Pushing hard will increase wear on these wheels, so have a spare set handy for competition time.

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 features the 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 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.

• Two 40 Tooth gears yeild a 1:1 ratio
