Team 330 Presents - Beach 'Bot 2011
 

Team 330's entry for 2011.

Re: Team 330 Presents - Beach 'Bot 2011
 

Well there's a surprise :p

If it works anything like it's near twin you guys should have a great year.

Re: Team 330 Presents - Beach 'Bot 2011
 

Team 330's 2007 robot was by far my favourite of that year. I'm looking forward to seeing the 2011 version in action. If it's anything like the '07 robot, it should dominate.

Re: Team 330 Presents - Beach 'Bot 2011
 

This reminds of the same mean robot I was in 2007. It was so simple and efficient and worked flawlessly. Great robot again!

Re: Team 330 Presents - Beach 'Bot 2011
 

Wow. That is beautiful!

Re: Team 330 Presents - Beach 'Bot 2011
 

Beautiful bot, I'm sure the 8 wheels will keep anyone from pushing you around on the field. Look out Arizona, 330 is looking for a repeat :)

Re: Team 330 Presents - Beach 'Bot 2011
 

Nice render!

Re: Team 330 Presents - Beach 'Bot 2011
 

I miss the wings.

Re: Team 330 Presents - Beach 'Bot 2011
 

Nice! You should have put the plamps on just for kicks!

Re: Team 330 Presents - Beach 'Bot 2011
 

Would you mind uploading the pic to CD for those of us stuck behind internet blocks at work?

Re: Team 330 Presents - Beach 'Bot 2011
 

I'm absolutely shocked by the lack of the kop FP gearboxes!

Re: Team 330 Presents - Beach 'Bot 2011
 

You mean that big black plastic thing at the base of the arm tower? :yikes:

Re: Team 330 Presents - Beach 'Bot 2011
 

Totally missed that on my phone. I saw what looks like a silver box off the side and assumed banebots.

Re: Team 330 Presents - Beach 'Bot 2011
 

So, did you guys go through your regular design discussion/strategy phase or was it modified/shortened due to the 2007 robot's success?

And is it happy with the crate? :)

Re: Team 330 Presents - Beach 'Bot 2011
 

Looks like another great design from our Neighbors! Best of luck this week in Arizona and best of luck getting it in the crate and back to LA for the following week!

Re: Team 330 Presents - Beach 'Bot 2011
 

That does look a lot like a BB gearbox hanging off the intermediate stage of the gearing.

Ever year I'm impressed by the Beachbots ability to pump out amazing robots that look so incredibly clean and simple

Unfortunately I won't be able to see much of its debut with my team competing this weekend, but hopefully some video will get posted afterwards.

Re: Team 330 Presents - Beach 'Bot 2011
 

Thanks everyone!

It's actually a photo with the background whited out.

Will do.

The fisher price on the arm will never die :p

We went through the same system design process as usual. We still considered different design types (arm vs. lift), but ultimately ended with the same answer. We combined our past experiences and lessons learned from 2007 which accelerated some aspects of the design process and allowed us to greatly improve on our 2007 bot. This robot is more efficient and easier to drive.

Re: Team 330 Presents - Beach 'Bot 2011
 

Really? The claw looks too pretty to be real. :)

Re: Team 330 Presents - Beach 'Bot 2011
 

I thought the same thing at first...

Re: Team 330 Presents - Beach 'Bot 2011
 

Someone should ask it that after it gets out of the bag.

(OK, so it's in the bag in the crate for transport to Arizona right now...)

Re: Team 330 Presents - Beach 'Bot 2011
 

So, Let me get this straight, y'all have 3 robots?! 2 practice and 1 competition?

Re: Team 330 Presents - Beach 'Bot 2011
 

From left to right:

2011 Practice Robot, 2011 Competition Robot, 2007 Competition Robot (without ramps)

Re: Team 330 Presents - Beach 'Bot 2011
 

Wonderful. Insert "great minds think alike" comment here. :)

How does it extend over the bumper? Is it similar to Shaker's arm?

We were generally happy with the arm design this year. Our problems with it at WPI were chalked up to a lack of driver practice and coordination: you need that to grip the tubes in an ideal location. Also, our PVC arm had a lot of flex which contributed to an already harder-to-control long arm system.

Of course, 330's ace in their sleeve is always their driving, so I guarantee they will do amazingly with this design.

Re: Team 330 Presents - Beach 'Bot 2011
 

While the end result does look very similar to 2007, there are a lot of subtle changes to make it play this year's game better and meet this year's rules. Had we decided to just do what we had done before, we'd be at a disadvantage compared to everyone else. Getting all the geometry right was quite a challenge.

• The bottom paddle has been optimized to pick tubes off the ground much better then 2007 ever could.
• The arm extends to meet the bumper perimeter requirements and still floor load.
• The main arm structure is at an angle to allow room for the minibot deployment.
• Jaguars on the drive train make it move much more smoothly then 2007 did.
• 8WD makes it the hardest robot to push that we've ever made.

There's probably a lot more that I'm not aware of.

Re: Team 330 Presents - Beach 'Bot 2011
 

There is a 12" stroke, 3/4" bore air cylinder tucked inside the arm which extends and retracts it.

We had used PVC back in 2005 for the arm, but for rigidity and ease of mating components (square aluminum extrusion for lower portion of arm), we opted for a fiberglass tube. We are using the same fiberglass tube for 2011 as we did in 2007.

Re: Team 330 Presents - Beach 'Bot 2011
 

The reason I asked is because 330 is known for spending a lot of time in design/strategic discussions before picking up a single tool. I figured you would do the same this year even though you could use 2007 as inspiration. I've always wanted to be able to sit in on some of your sessions and learn, learn, learn how to approach a design and the reasons behind the approach. It would be fascinating. :)

Re: Team 330 Presents - Beach 'Bot 2011
 

Getting the arm rigid enough to overcome a low bending mode is something I have seen many teams fail at doing successfully. You guys seem to have nailed it! I heard that Joe can nail the positioning within 1cm or so.

Re: Team 330 Presents - Beach 'Bot 2011
 

Shane,
Looks great!

We got the same drawer slides and setup, battery and compressor in exact same spots, and similar claws. :rolleyes:

Is that a triple reduction I see?

Re: Team 330 Presents - Beach 'Bot 2011
 

Looking really nice, can't wait to see you guys in LA

Re: Team 330 Presents - Beach 'Bot 2011
 

Looks like a double reduction off the gearbox with another gear for tensioning/position sensing.

I'll see about watching any webcast on Friday or Saturday if I can...

Re: Team 330 Presents - Beach 'Bot 2011
 

Confirming what Eric said - just a dual reduction like past years. That sprocket is there for tensioning purposes.

Re: Team 330 Presents - Beach 'Bot 2011
 

I hear that Falcons are trying to set up a webcast, hope it happens.

Looks like a great robot in the pics, I'm sure it will look even better in real life tomorrow! Should be a fun regional

Re: Team 330 Presents - Beach 'Bot 2011
 

Man, I feel kind of dumb. We probably have that exact fiberglass tube in our shop and I don't think anyone has thought to use it.

Re: Team 330 Presents - Beach 'Bot 2011
 

Yeah fiberglass is awesome stuff when you want something lighter than aluminum and still super rigid. The pultruded stuff is also really easy to work with.

Re: Team 330 Presents - Beach 'Bot 2011
 

Is there any reason to putting the FP and it's gearbox down at the bottom besides to lower the CG?

Re: Team 330 Presents - Beach 'Bot 2011
 

I call shenanigans! You guys totally stole that design from the Hawaiian Kids ;)

Re: Team 330 Presents - Beach 'Bot 2011
 

Lowers CG, plus it just wouldn't be a BeachBot if an FP were high off the ground. :)

Every FP that has been on a 330 machine has been close-ish to the ground. Winches low down, arm power sources low down, I can't think of a single FP that made it higher than 2' from the ground on a 330 machine (except maybe in 2009).

It also gives a good chance to get extra reductions via chain and sprocket.

Re: Team 330 Presents - Beach 'Bot 2011
 

I hope we can do as well as them.

Re: Team 330 Presents - Beach 'Bot 2011
 

Logomotion was my rookie year, and my first FIRST event was at the 2011 AZ regional.

Along with all the other rookies on our team, I was the most impressed by Team 330's Beach 'Bot. (Falcon Robotics was a close 2nd). From the handling of the 8wd, to the ease at which that killer claw picked up tubes, I coudn't have found a better robot.

Great Job guys, hope to see y'll next year!
