Unbelievable bot as always. Your swerves blow my mind every year.

Re: Bomb Squad 2015: Two Minute Warning
 

Those can grabbers are so cool!

Re: Bomb Squad 2015: Two Minute Warning
 

Dat Swerve, fantastic as always :D

Re: Bomb Squad 2015: Two Minute Warning
 

I DEMAND A RECOUNT! That was only a one-and-three-quarters-minute warning. :P

Another fantastic Bomb Squad machine! I can't wait to see it in person on down the road.

Re: Bomb Squad 2015: Two Minute Warning
 

Great job, can't wait to see this awesome machine preform at Arkansas!

Re: Bomb Squad 2015: Two Minute Warning
 

In your autonomous run you seem to be missing 2 containers, what up with that? Also, with mercury explicitly banned this year are you still running a similar swerve to previous years?

Can't wait to see it up close at champs.

Re: Bomb Squad 2015: Two Minute Warning
 

That's what alliance partners are for, right? ;)
I actually just got back from working on an auto that only requires one RC to be taken away by alliance partners. It should be ready for Rock City.

Similar modules, just bigger and heavier.

How is Leroy?

The robot looks good, gonna have to poke around it at CMP again.

Re: Bomb Squad 2015: Two Minute Warning
 

Best use of a DART I've seen.

Re: Bomb Squad 2015: Two Minute Warning
 

Amazing bot as always from the Bomb Squad....Good luck this season guys!!!

Re: Bomb Squad 2015: Two Minute Warning
 

Those arms are so nifty! I can't think of a better word to use. How many totes can you stack at one time? Your elevator doesn't seem to be the most efficient design in terms of space.

Re: Bomb Squad 2015: Two Minute Warning
 

My my, those hooks look beautiful. Love this design; it's just like industrial manufacturers and warehouses would do this job.

Re: Bomb Squad 2015: Two Minute Warning
 

I am so glad I get to see this at Midwest. Hopefully we don't end up against them.:D

Re: Bomb Squad 2015: Two Minute Warning
 

I like the top pivot swerve.

Re: Bomb Squad 2015: Two Minute Warning
 

Another awesome machine from the Bomb Squad. Looking forward to sharing the field with you guys again in Arkansas!

Re: Bomb Squad 2015: Two Minute Warning
 

Is that a CIM-less drivetrain? Dang, that's so old school.

Nice robot! Wish I could see it, but I likely won't be at any of your competitions. :( Best of luck this season!

Re: Bomb Squad 2015: Two Minute Warning
 

Question - when was the last time that Bomb Squad had a tall robot? :) Looking as amazing as ever this year, and that swerve driving is just soooo smooth.

Re: Bomb Squad 2015: Two Minute Warning
 

2011.

Re: Bomb Squad 2015: Two Minute Warning
 

I can only imagine how useful it will be to have each tote and bin supported by an individual hook. Already I've seen a lot of tipping when teams try to move around stacks of 4+ totes.

What was the inspiration behind the name of this year's bot?

Re: Bomb Squad 2015: Two Minute Warning
 

In the early days of Team 16 our robot's name was 2-Minute Warning. This was based on the 2 minute matches that they had back in 1996. We thought it was a great way to commemorate our 20 seasons of robotics.

Re: Bomb Squad 2015: Two Minute Warning
 

It sure is. CIMs are heavy.

Re: Bomb Squad 2015: Two Minute Warning
 

Love the bin grabbers, love the robot! :P

Re: Bomb Squad 2015: Two Minute Warning
 

We can hold/stack 5 at a time. The spacing was intentional in order to completely raise the bottom tote we are holding above the next tote to be picked up. Given the other constraints around the robot and other objectives, we couldn't get 6 totes and have sufficient spacing. Therefore, we maximized the amount of space between totes to make the pickup as fast as possible.

Re: Bomb Squad 2015: Two Minute Warning
 

That looks familiar. :)

Can y'all pick long-ways also? It seems to be more forgiving that way.

Re: Bomb Squad 2015: Two Minute Warning
 

Those hooks went through a lot of iterations to get them just right, but it's made for a super-solid hold on the totes. I have tested their sturdiness on several occasions with over zealous poor controls. They definitely don't come out of there easily.

Re: Bomb Squad 2015: Two Minute Warning
 

Awesome bot as always. I'm jealous of how awesome the container grabber is. Can't wait to see you all again at Rock City. It is always a good time.

Re: Bomb Squad 2015: Two Minute Warning
 

We can, but there's extra tote sag. We have a kicker which is connected to the same tubes as the brake. The kicker prevents sag on the bottom-most tote, but we have issues if the kicker moves too fast or pushes too hard. We're working on a deeper hook design for Pittsburgh next week, so hopefully that resolves that issue. In retrospect, we like the sag on the upper totes since they rest against the 2 vertical rails, keeping them stable during turns.

It's refreshing to see another team pick a very similar design and have success with it. I know some of the struggles you went through to get this working correctly. For me it was one of the most challenging designs my team has ever put together, but it was worth it.

If we find anything to help with some of its nuances, we'll share notes after Pitt!

Re: Bomb Squad 2015: Two Minute Warning
 

I love your dual container grabbing claw!

Re: Bomb Squad 2015: Two Minute Warning
 

Yeah, we went through about 10 iterations of the tote tab design. We finally settled on something acceptable, but positive change is always welcome.

Re: Bomb Squad 2015: Two Minute Warning
 

i was wondering if you might post some cad pic of your swerve this year?
i would really appreciate it.

Thanks. Tristan Shepard
