Team 233 (The Pink Team) Roccobot 2k7 Videos Unveiled! [Archive]

Do you have any videos of the robot picking up donuts from the ground or scoring on the top?

Yes it can pick up game pieces or "donuts" off the ground but we were testing the robot on concrete (we do not want to ruin the paint job).

Yes it can score on the top spider.

Most of the video we have captured was initial testing of the programming software. Since this was done on "Happy Ship Day" we were limited on time.

In other words, we unfortunately do not have video, and everybody is going to have to wait until UCF. [Plus we need the time to fix any small bugs we couldn't finish before we shipped it]

You guys think your so smart with you nice weather and practicing outside in the winter. :p

Nice job as always to bad your not coming back to Boston or BAE.

When you rotate the tube it slides towards the end of the claw, do you have a sensor(limit switch) so you can make sure the tube stays in the gripper, or is the arm operator responsible for this?

You have a very good eye. Yes we do have a switch at the "throat" or the bottom part of the manipulator. The arm operator is not responsible for this. Roccobot 2k7 automatically compensates for this.

I will post a picture of the switch later today.

Interesting that you did not choose to build a ramp. Although I agree that at the championship, it will not be necessary for everyone will have one, at both regionals, you will be crippled in 2-3 matches.

From what I see on the FL Regional Post, 8 out of 19 teams have ramps. That is about 1 out of every 2.5 bots will have one. So, in 9 matches of seeding, you will be stuck with 2-4 matches without a ramp bot. Should the opposing team have a ramp bot, you will be likely to lose more than half of those matches.

Also, it is hard to tell whether your claw will quickly and effectively pick up ringers. However, the rotating manipulator is incredible, and those tires look deadly. Can't wait to see you at the regionals and nationals... you should, as usual, be a force to be reckoned with.

Should the opponent have a ramp/lift bot that WORKS, alliance partners that can climb on the ramp/lift, alliance partners that DO climb on the ramp/lift, and either enough offense or enough defense to hang with what will likely be a superior tube placement teams (judging purely by 233's pictures and track record, they should be in the top few tube placing teams at each regional they attend). Then 233 might be in a little trouble.

The entire robot is just plain old amazing if you ask me... But something that caught my eye is that your robot appears to be in the 5' hieght class.. Is this the case? Your manipulator is awsome, your probably going to be one of the most efficient scorers out there, just watch out for deflated tubes....:yikes:

Nice bot, as always from the Pink Team.

I see that Kit has you guys running through his driving tests.... outside. Let Kit know that we have about a foot of snow up here in Kokomo.

Best of luck,

What kind of rails do you use for the tower and how thick are they because it seems that there is hardly any space in between each stage.

HELLOoooo from the North East:D
Well another great job on your bot, it can score easy and holds the tube super. Keep up your TEAM WORK and the exceptional TEAM SPIRIT !!!

I'm not too great on terminology, but we just use the square aluminum tubing, we only have two stages this year, and the final stage is the exact thickness of the black "snake" as we have come to call it (thing used for wires)
unfortunetly I do not know the exact dimensions...sry, but yeah, the is very little space between stages, just enough for a chain, luckily we've been blessed with fantastic facilities : )

The inner section is 1/8 wall thickness aluminum tube that's 1 inch square on the outside. The outer section is 1/8 inch wall, 2 1/2 square Al tube (with lots of lightening holes).

Kit nailed the thickness of the metal on the arm: 1/8" thickness, inside tube is 1" square and outside tube is 2.5" square (aluminum).

I talked to one of the mechanics (Mike D.) who helped us out and he said that, "there is 5/8" in each side of the box and we use Delrin rollers in each side. The chain is used to move the inside tube in and out."

So I hope that answers your question, FDA1029.

yes it does because we used the same telescoping method but we used teflon so the each stage can slide easily.

Another question, how did you align the wheels? Because Pneumatic wheels grip really well the the floor which tend to give too much traction and make it harder to turn.

Delrin aslo makes it slide very easily and is farely durable, but we have a 6-wheel tank drive with the middle wheel lowered 1/8th of an inch so that we can turn much easier.

We've been curious which part of the PNW site will become a ramp graveyard as teams realize their ramps don't work as advertised and remove them entirely from their machines.

Wow thats very interesting do you have a pic of the wheel in the center?

Um, I can get it for you, We've been using the design since 2004 or at least since 2005, It works fantastically, allowing for only two wheels to grip during turning and such, but still leaving lots of traction : D,
It's kinda hard to show since it's only 1/8th of an inch difference as far as a pictures view point (not the driving aspect) and this year's robot is in the crate already, but next week we're getting last years robot out for a demo so I can take a picture of the axle holes?, its the same wheel as the others, just axle is set 1/8th of an inch below the level of the rest.

FDA1029

27-02-2007, 17:20

Oh, I thought that was the way you we're driving the robot this year but I didn't think the middle wheel was dropped because it looked like the robot did not tilt at all.

We've been curious which part of the PNW site will become a ramp graveyard as teams realize their ramps don't work as advertised and remove them entirely from their machines.

I have been a bit curious to how effective the ramps will be this year. If the ramps are efficient, I still think teams will adjust to the game (well they kinda have to). If teams find out their ramps do not work, will teams have enough time to build an arm to score on the rack during competition? I guess we will find out in a few days.

Oh, I thought that was the way you we're driving the robot this year but I didn't think the middle wheel was dropped because it looked like the robot did not tilt at all.

It doesn't look like it tilts because it is only 1/8th of an inch. I do not have a photo of the side plate in which you can see the difference of the placement on the axles on our robot, mainly because it is very difficult to notice the difference; it is there I swear! If you want, swing on by our pits for a closer look at UCF.

Out of curiosity, what happened to the tower? I heard bits and pieces, but never a clear explanation. I'd understand if you don't want to post the answer to the public, so don't feel any pressure to.

Your robot looks great. It seems like it'll be another beast from the Pink Team after you guys work out your bugs. Good luck in Las Vegas!

The bracket we made for the tower this year had round spacers which led it to have a TINY bit of give, wtih only a two stage the tower was smaller and with that little bit of give, and heavy manipulator, it began to do ugly things to the tower, so we made an UBER bracket overnight : D, now I can say with the utmost confidence that the tower is completely fine and it would be ALMOST impossible for any. The tower was not damaged or disconfigured but IF we had ran it for those practice matches / 3 first Qualifying matches it could have damaged the tower. I say again, the bracket has replaced the round spacers, taken aaway the give, and tripled the surface area as to which the force of the load hits the tower ensuring pure happiness

So i wasn't just hallucinating... I could have sworn that the first day the tower didn't have this little bracket on it but the 3rd day did.... weird.. :p

During the build season we "build" our robot on CAD. By week three we start to fabricate the parts needed for assembling the robot. By the final week, the robot should be close to fully assembled (hopefully).

Since we have all of the dimensions on file, we can quickly figure out how to build the pieces. With a few dedicated members including a very crafty machinist (Mike Dininny) and permission to work at the KSC prototype lab (where we build the robot this year) the team was able to quickly build the brackets needed for competition overnight.

Unfortunately we missed out on our first three matches the next morning. The team agreed it was best to miss three matches than to have no arm for the rest of the season. It is a difficult decision and we are sorry for our alliance members during those first matches.

I'm happy that you were able to make your robot function, as it obviously inspires a lot of folks to push themselves to be better each year, but isn't this a violation of <R21>?

<R21> At the competitions: Teams are allowed to repair, modify or upgrade their competition
ROBOT while participating in a competition event. To support this, teams may bring
SPARE, REPLACEMENT and UPGRADE PARTS and COTS items to the competitions
(within the limits specified in Rules <R30> and <R31>). Work can only be done on-site in
the Pits or at any facility made available to all teams at the event (e.g., in a team’s repair
trailer or a local team’s shop offered to all teams to use). Fabrication may be done when the
Pit area is open for normal operations during the period starting with the opening of the Pit
area on Thursday and ending at 4:00PM on Saturday. All work must be completed when
the Pit area closes each evening. Parts cannot be removed from the competition site and
retained overnight after the Pit area closes.

Perhaps I am misunderstanding what it is you mean when writing that the part was made "overnight."

Thank you for pointing this out. I was not with our machinist when the team was making the replacement bracket. From what I remembered work was done early in the morning and quickly brought over at UCF for competition.

This makes more sense that we missed the first three matches when we started fabrication in the morning (when pits opened). I am pretty sure the brackets would have been done if we worked on them late the night before. I am confident that our pit crew is aware of the rules on fabrication.

Sorry for misinforming you all.

unless the machine shop was made avaliable to all teams, I believe this would still be a violation of <R21>

Please allow me to check with the pit crew to see what exactly went on. I do not want to convey any information that I do not know.Here is the scoop, and it's kind of embarrassing for a veteran team like ours. We did, in fact, violate <R21>. Work was done in our shop, which is not available to other teams. I hadn't read these rules in a long time, and apparently neither had anyone else on the team. This will be a major learning experience for all of our team members. We need to read the rules, all of them, and then comply.

UCF is over and there is nothing we can do about what happened there, but Las Vegas and the Championship lie ahead for us. What we will do to be completely legal for those events is to use the "FIX-IT WINDOWS" described in <R22> to remake the reinforcing bracket for our tower. We will install the remade parts on Thursday at Vegas.
