Go to Post Well, air conditioners when pointed inside the house make it cooler. So I figure if EVERYONE turns their air conditioners on full blast and just point them out the window, we should more or less get rid of this "warming" nonsense. - Mike [more]

Gears Vs Balls: The Great 2017 Debate

For some reason, a debate on "which one is better" is still happening. It turns out, they're fairly well-balanced. Gears have a better chance to get more bonus points as an alliance, but bot-for-bot - they're about even.

The model behind this graphic is here.
(be patient with that site - it's sluggish since it does a LOT of calculations live).

A model for a single robot is here.

JesseK,

Am I interpreting the model correctly in saying that the Ball Bot does not place auto gears, but places between 2 and 3 gears in teleop?

It seems this model is assuming a robot focusing on balls shoots into the high goal in auto, while a gear robot focuses on scoring its gear.

If you can do both, you probably don't need this model to decide which to focus on!

Correct. The ball bot in this scenario focuses on doing a Hopper in autonomous rather than spending any time doing a gear. The reasoning is that the shots need to be processed in auton to be scored in auton, therefore to reduce complexity in how the scenario is explained a bot does either one or the other.

Personally, I think 2-3 gears in addition to 2-3 HG cycles is more difficult than 5-7 gears.

What if you get your gears and balls in the same place at the same time? And there's a gear peg you can score on while shooting your balls into the high goal? This is just one way to do it.

It's certainly more difficult to design a robot that does both than it is to design a robot that does 5-7 gears per match every time, but once the robot exists it's not so hard.

I don't agree. High goal cycles are not nearly going to take as long as a gear cycle just due to proximity to the collection/intake position and the time it takes to take score 65 balls. Not even considering the defense being played on gears. Getting 5-7 gears for a single robot, in general, is the most difficult task.

You believe that on average, teams will have a lower cycle time for 65 scored balls than a single gear?

I have a bridge I'd like to sell you....

I'm not assuming the average robot is going to be able to do 5-7 gears, and this assumption is heavily based on the thought that if a team cannot shoot balls efficiently they should really just cycle gears. So I apologize if my post was misleading. Reasoning below:

A team capable of performing at a rate of 5-7 gears in a match, could score 3 cycles of balls + 2-3 gears a lot easier than 5-7 gears. Assuming you are shooting the balls at 3-4 balls per second, it'll take you about 15-20 seconds to score the balls. The time it takes to intake will probably close to 5-10 seconds. So you're looking at about 30 seconds to score 65 ish balls.

Now, looking at the gear cycles, it'll be incredibly difficult for this example team to shave their time down underneath 20 seconds for each gear. If the other team hits a certain threshold of gears there is going to be an incredible amount defense to prevent you from scoring your 6th -7th gear (3rd rotor).

There is also a huge vision driver advantage with shooting balls , you could get two cycles done without even having to go onto the opponents side of the field and effectively reducing the physical cycling distance by half.

The main issue is proximity to the scoring elements, the gears are going to be more challenging than people expect for sure with these huge airships in the way.
