I think the calculation allows a valid conclusion. Even if the gearbox were to completely lock up, the only effect it would have for purposes of this calculation would be the resulting friction between the (locked) wheels and the pole. Compared to 474 Newtons, such friction can reasonably be ignored for purposes of the conclusion, which is simply that a 3lb minibot traveling at 7fps which is decelerated to zero speed in 1/4" is exerting much more than 4 Newtons on the plate.
