Strafer Chassis KitV2(2:1 Ratio Bevel Gear Set (8mm REX Bore Pinion Gear))

Competition eligibility

Legal for FIRST Tech Challenge (FTC) and FIRST Robotics Competition (FRC). Eligibility is set by each season's game manual — check the current rules before you compete.

The Strafer Chassis Kit is a rigid, low-profile chassis that includes high-torque 312RPM planetary motors, ball-bearing mecanum wheels and a configurable chassis you can tailor to your liking.

Motors

At a glance, you might wonder, where are the motors? Flip it over and you’ll notice the nested 312RPM 7203 Series Planetary Gear Motors. Combined with the 101mm wheels, they give the chassis a theoretical speed of over 5.14 ft/sec. These motors drive all steel miter gears, heavy duty hubs, and ball-bearings ready for some low-friction strafing action!

Bevel Gear

The Bevel Gear, located near each of the four corners of the chassis, create a 90° drive so that the motors can nest inside the 3120 Series U-Channel. The Bevel Gear have been battle-tested, even with brushless motors, and are extremely stout. Do not worry about slipping as the bores are matched to the profile of the shafts they are mounted to.

Shafting

All shafts (including the motor shafts) are 8mm REX for maximum strength.

Wheels

The Sheen Robotics Mecanum Wheels are 101mm in diameter, have ball-bearing supported rollers, a narrow profile and steel side plates. Each wheel is only 260g - far less than the competitors. The reduced rotating mass yields quicker acceleration with less strain on the motors.

Frame

The channel framework allows you to pack all these premium parts in without having to clad on to the outside like some frames require. And oh-so configurable - move the center channels, adjust your track-width and more all with the same parts we provide.
