Drive in any direction with the Strafer® Chassis Kit! It utilizes mecanum wheels with diagonal rollers that allow it to drive sideways and diagonally in addition to conventional skid-steer style steering. It also features high-torque 312RPM planetary motors, ball bearing mecanum wheels, and everything else you need to make a rigid, low profile, extensively modifiable chassis you can reconfigure in any direction.
Motors
At first glance, you might wonder: where are the motors? Flip the chassis over to see four 312RPM 5203 Series Planetary Gear Motors seated cozily within its channel frame. These motors drive steel miter gears and heavy duty hub-shafts riding on ball bearings to make for low-friction holonomic action! Equip the included 96mm diameter mecanum wheels to give the chassis a theoretical speed of over 5.14 ft/sec.
Miter Gears
The motors owe their compact position to the 90° drive created by steel miter gears inside each corner of the chassis. Alongside profile-matched bores and an incredibly secure clamping mechanism that eliminates any chance of slipping, these gears rock a titanium nitride finish that helps them take on the toughest tumults of competition!
Shafting
8mm REX™ motor shafts and hub-shafts facilitate fierce positive drive and smooth maintenance of gear assemblies.
Wheels
96mm diameter goBILDA® Mecanum Wheels feature ball-bearing supported rollers, a narrow profile, and steel side plates. Each wheel measures only 207g—far less than other mecanums on the market! The reduced rotating mass yields quicker acceleration and puts less strain on motors.
Frame
Unlike other frames requiring exposed motion components, the Strafer Chassis can fit all these premium parts inside its highly configurable goBILDA® pattern 1120 Series U-Channel structure.
