Probably? Time to watch out for that robot at worlds then.

I agree, however (credit to pilleya for pointing this out):

So during autonomous period itself, only about 15*5=75 balls can be scored. How would the other balls be counted, if they aren't counted before autonomous ends?
It seems strange that FIRST would limit the dream of the perfect auto with a slow ball counter. To the Q&A we go!

They would be scored in tele-op, as mentioned in the field tour videos. FIRST pretty much states this is by design, so I don't think posting in the Q&A will change anything.

Re: Fuel Vs. Gears

Gears are all about cycle time. Look back to 2014 for an idea on cycle times. Now factor in the field is covered in fuel. If all the bins are dumped on the field, that's one mess of balls. Now what is the center line of a ball and what is the bumper height. What happens when your robot's bumper contacts the balls?
If your going to do gears, figure out how to drive in a sea of balls.

Re: Fuel Vs. Gears

At this point, we're thinking gears as our primary function (and a rope climb of course).

If these both go smoothly, we have two likely paths for an additional manipulator:

Bee able to gather balls in passing and dump them into the low goal or at the same height as the HOPPER (we'll need to do tall configuration for this) to facilitate passing fuel to a high goal scorer who is set up to load at the HOPPER. We'll be sure to have an optional autonomous mode which begins with dumping our ten pre-load fuel (into an alliance partner) before scoring our gear.

Gather gears from the floor (and get them to our hanger).

The one rank point earned by reaching 40 kPA is nice, but not as good two rank points from simply winning the match.
I think he was saying that if you score the 10 fuel in the high efficiency boiler that is 10 points and 10 kPa, so when you score your pre-loaded gear for 40 points in teleop you are now 10 points behind the 60 point autonomous gear.

Basically in my opinion hitting the top goal in auto an being able to hit 20+ in 15 secound which should not be hard. Makes get the extra ranking point a ton simpler and quicker
40 high goal is auto equals a ranking point
120 high goals in Telekom is a ranking point
Don't get me started on low goals
Except the thing you are forgetting is that you can only start with 10 balls in your robot, making 10kPa the cap.

If you can trigger the hopper and collect and shoot those balls, it is possible to reach 40 kPa in auto

Also that amount is under the hypothetical 75 fuel limit for counting during autonomous (15 sec * 5 fuel/sec)

realistically, this is helped timewise by shooting at both goals. our team is discussing this option. This brings the 40kPa fuel processing time from 10 seconds to around 6.

Re: Fuel Vs. Gears

Team 1571 is considering the possibility of shooting multiple fuel into the high goal at the same time. Each fuel is 5 in. wide, and the high goal is 21.5 inches wide with a decently accurate shooter (vision targeting will be handy here) it is possible to realistically score 2 or 3 fuel at the same time.

Is this true?
Is it 5 fuel/sec in the low goal and 5 fuel/sec in the high goal?
or is it just 5 fuel/sec?

the high goal and low goal have separate processing and counting. Each averages ~5/sec

Re: Fuel Vs. Gears

We debated the ability of just gears because they give a lot of points. But in order to get a Ranking Point, assuming you are the only robot placing gears, you need to make about 12 shuttle runs between the feeder and the airship. In previous years and games, some of the best teams were only able to make 7 or 8 runs across the field. We decided that is was seemingly impossible to get a Ranking Point by yourself. Just my thoughts.

There is, however, a tech foul given to an opposing team if an opposing robot touches your robot with any part of it inside your retrieval zone, regardless of who initiates the contact (Rule G13). If your robot can reach the retrieval zone with a reasonable amount of speed, most robots won't be able to defend against you obtaining the gear. Even if they try not to touch you, in the retrieval zone, bumping them to still gives them a tech foul, because no one can touch you in the retrieval zone.

While it's true an opposing robot can just prevent you from reaching the retrieval zone in the first place, that's a lot harder to do, and depending on the robot, not worth the time and the points they could be scoring instead of preventing you from scoring.
