The gear is a 12 tooth, 16 diametral pitch, 20 degree
pressure angle, stub tooth.

This gear can mate with a standard gear by either
increasing the center distance a bit. This increases
the backlash a bit too, but nothing too bad considering
the typical FIRST robot. Another method is to shaft off
.4/D.P. (in this case .4/16=.025&quot the diameter of a
standard gear. Alternatively, you can have a stub gear
cut from legal kit materials.

P.S. Come to think about it, the last option is the
only real option this year since, to my knowledge,
mating gears (standard, stub or otherwise) are not sold
by Small Parts and gears are not on the Additional
Material List.
