  The greatest grippy wheels for competition robots are available in small batches of your favorite colors. All wheels, regardless of color and diameter, have a durometer of 35A and use white hubs to differentiate them as custom. This is equivalent to the typically green wheels. All other properties are the same as normal such as expansion rates and maximum speeds.
  
  Compliant wheels are not intended for moving robots, but moving objects. Compliant wheels give way to allow rigid objects to be manipulated easily. A line of multiple wheels on a driven hex axle creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors.
