I don't know, I'm not a referee

Uhm, isn't that bad?

ya, carrying is illegal

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

That's definitely not how they hold the ball normally. It only occurs when you go too far into the goal. I'm sure they already know they can't do that and are practicing to make sure they never do.

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

But is it carrying the ball when the bot is driving around on the flat parts of the playing surface? Technically, the ball could still be touching the ground when the robot is on level ground. But, if the situation in the above picture happens, does that even matter?

I apologize if this has already been covered in an update/Q&A. I'm currently abroad in Thailand and unable to build this year. :(

To me, what is most impressive to me is this --

There are many teams that will build their robot, ship it, and compete with it in some events and just fix things when they break. They would be 'satisfied' and take a rest.

Knowing 148 and their mentors, they will take the "design is an iterative process" philosophy and continue to update, revise, modify and improve this machine all they way through the Championships and the machine in April will be much different from the machine that goes into a crate on February 23rd. They will see what other teams have done, they will see what works and what does not, they will see how this game plays out on the field and make the adjustments and maybe make major changes.

That is how great teams do it, and that is how great companies do it.

If you have not, read JVNs design paper, read it.

And once again, great job 148!

I'm not a ref either, but I do know that the GDC has ruled that if the ball is possessed and comes off the ground, it is carrying, period. Now, whether or not the refs catch it is another matter.

Still, with 65 lbs and a couple weeks to work with, I'm sure 148 will come up with something to keep the ball down on the ground.

Read it, and live it, if you can. It takes a LOT of work, motivation, and leadership skills to keep improving the design continuously! Kudos to 148

Make that twice again :) Awesome machine

The situation above isn't going to happen. It's not a design flaw. It's an issue of the drivers letting go of the ball before going too far into the goal.

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

If the drivers have to let go of the ball, then they were holding onto it, which is what CARRYING is all about?

It looks a bit iffy to us mere mortals.

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

Not saying I know how their ball magnet works, but ...

If they reverse it and make the tip of the roller go the same speed of the drive train x2 then it'd be impossible for them to carry regardless of what the drivers do.

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

If you look at 1:54 on the video, you can see a yellow upper roller (if it is a roller) and a black lower roller. You can also see them holding the ball at 2:01. Hope this can help shed some light on the subject.

I love this robot, it's genius. 148 always inspires a little jealousy in me each year.

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

I think the best "soccer analogy" would be if you pinched the ball between your feet, you'd have to let go before jumping if you wanted the ball to stay on the ground for whatever reason.

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

I love the hanging. What an amazing looking and capable robot.

Re: pic: Team 148 - Robowranglers 2010 - Armadillo
 

We just turn off the magnet now before going up the goal ramp...
That won't happen in competition.
