Re: 2601 Three Ball Auton Teaser
 

Why is that?

G5: Are teams allowed to *not* pre-load balls for auto when they are starting in the white zone? I didn't see anything in the rulebook saying what to do with balls in auto that aren't loaded in a robot that has reported for the match. Are they placed in the white zone wherever they please or are they removed from the field?

Re: 2601 Three Ball Auton Teaser
 

If a team starts in the goalie zone their ball can be placed in the white zone wherever the alliance see's fit. Also you don't have to preload a ball if a team chooses not to preload a ball or start in the goalie zone the ball will be left off the field.

This is awesome!

My question, how consistently can you line up those three balls to push in the right direction/roll to the desired locations? From my experience with the practice scrimmages this weekend, getting balls to settle in the perfect spot is hard, plus each ball is unique in inflation and shape. Seems like this approach is highly dynamic. Are you using any feedback to make ball acquisition more consistent?

Regardless, very impressive and unique approach to the three ball auto problem, well done!

I can't wait for competition this year for many reasons... two of which are:
1.) 3 ball autos (or any multi-ball)
2.) The one goalie bot that blocks all three of them with PVC and sends an entire alliance running :yikes:

Thanks Mike. This demo was all dead reckoning, but we had some ball tracking in the works. Whether or not it's going to actually be implemented we don't know.

Our pneumatics expert (the guy filming) ran around the gym screaming for a solid 15 seconds after this test.

I already knew that, hence why I asked "...if the robot starts in the white zone..."
Is this states officially anywhere in the rules? It says you may preload a ball if you start in the white zone. But it doesn't specify what to do with the ball if you don't preload it, I would assume that it's just removed from the field.

Re: 2601 Three Ball Auton Teaser
 

Q. [G5] At the start of Autonomous, 'bots in the white zone "may" be in contact with a ball. Does that mean that there is an option not to? If so, may the ball be placed elsewhere in the white zone? Or is it removed from the field? (Not clear from the rules.)


A. G5 requires that BALLS preloaded be touching the ROBOT. The "may" allows TEAMS to decide that they do not want to preload a BALL, in which case the BALL is removed from the FIELD. The only exception is for BALLS associated with ROBOTS that are not present for the MATCH or begin the MATCH in the GOALIE ZONE.

This actually seems to be pretty clear. You cant have a "free" ball in the white zone. It either has to be touching another robot or off the field.

Man, to bad you guys did not post a video of him also.

But besides that, awesome job on doing a 3 ball auto, my only question is how repeatable is it?

Re: 2601 Three Ball Auton Teaser
 

Very impressive. Any plan for the third ball rolling left/right instead of straight forward?

Re: 2601 Three Ball Auton Teaser
 

Thank you for finding that, I missed it in the Q&A.

Re: 2601 Three Ball Auton Teaser
 

Very impressive. Looks like 2601 is going to make a big splash this year, you guys just keep getting better and better.

I worry about getting those balls to line up consistently, but I see no reason why that robot can't easily run a consistent 2 ball auto regardless.

Re: 2601 Three Ball Auton Teaser
 

Vinay and I are really happy right now.

On consistency: here's trial two (with Alex's reaction).
