Balancing more then one requires a bit more precision, and three is quite a trick but one is very doable without any fancy stuff (like worm gears?).
And finally, [G25] Robots may not contact or otherwise interfere with the opposing Alliance Bridge. Violation: Technical-Foul. If the act of Balancing is interfered with, also a Red Card and the Bridge will be counted as Balanced.
You need to get your facts straight or you're going to be very suprised come competition season.

Forgot that rule, but regardless, there will need to be a stop on the bot (worm gears cannot be fed the opposite way to move thus creating a permanent stop to wheel motion). Balancing will be hard even with one robot with no stops on it. And one team would have to make sure the stopper doesn't accidently get inside one of the 15 holes on the bridge. Also, robots are allowed to "block" the bridge if they just happen the stop to shoot in front of your bridge. I understand the field flow of motion cannot be obstructed, but even 10 seconds of moving can affect a chassis balancing team.
And actually holding three balls then shooting them is almost 2.5 pounds to shoot. There is no way to shoot that much weight at one time from 10 plus feet. that is too much torque that when geared down, is too low an RPM even with the CIM motors. Our design holds 2 yet the bot will only weigh around 50 pounds and is an active collector and shooter from literally all spots on the field. A collector in this game may not be worth it since it would be difficult to drive a ball into the narrow side of the bot that has a maximum of 11 inch opening and the wide side (22 inches) where any corners could damage the ball by running over it. (and the ball is also 8 inches in diameter which means a claw in that area would have to be very slender) Also, the driver will be 30+ feet away to gather the balls if it hasn't any in the bot itself which could be facing away from it. The driver is threading a needle.
