The design is totally by us...the gears are off the shelf tho..... the outside parts were machined by us. The housings etc... are not shown here but that is basically everything other than motor mounts etc, but this piece by itself is 4" in diameter.
it can drive our robot from 2 ft/s to 15 ft/s .... that is w/ a 3.6 reduction at sprockets....i think...
