Thumbs up Nice Work T3

Great robot.

I've been waiting to see what T3 would come up with for this year. I am impressed.

Seems to me that any pushing of the arms will not cause playing field damage, only arm damage by pinning/ramming them into the the midfield bar. And knowing T3, they carry more spares than any other team in FIRST.

It is an interesting interpretation of the rules. Any team that rams the arms WILL be pinning the T3 'bot to the midfield barrier. I'm certain there were many such discussions amongst the team about the legality issues and I KNOW that Mr. Evoy and others would not build a bot they thought to be illegal.

Pinning is, of course, LEGAL for a limited time period. You push a robot into a corner, and the robot is 'reacting' to the side of the playing field. That's simply physics. No robot operation or function is caused by the incidental contact.

I think it is an ultra clever way to stop robots from trying to pin the T3 machine.

It's not unbeatable or unfair, it IS a solid looking robot.

Frankly, because all we see is pictures, who know if they will ever touch the barrier. Outriggers plus solid traction and the limbo-blocking legs may not even come into play.

I can't wait to see it in action.

What blows my mind is that it was underweight. A Truck robot underweight? Never saw that coming.

Adam

You have an intimidating robot Magnasmific, but that doesn't give you permission to get cocky about it. Your robot isn't perfect, neither is ours, or any other bot out there. Your robot does a spectaular job handling one aspect of the game, but rest assured, there will be more than a few robots that will be able to show you up.

Team's would not be pinning T3 is they ram them on the limbo rails. Pinning is defined as blocking all movement of another bot. If a team pin's their legs to the pole it's not illegal because T3 can still drive their motors or retract the legs. I expect the legs to break at some point with field damage as a result.

I think 68 may have been a little hasty with their mechansim, they have very little clearence when both passing over and locking down their legs from their mechanism to the lexan.

When in semi-perfect position, those arms look like they are less than 4" from the sidewall's top. if they get too far to a side their legs will be useless.

I wasn't trying to be "cocky", and i apologise if it came across this way. I was simply stating that this was a very difficult thing to build, and that it would be hard to imitate during a competition (rebuilding a person's robot), it had nothing to do with showing off. I thank everyone once again for their input and we will defineatelly take everything into consideration

Great Robot

As always, team 68 has done an outstanding job! I come from a team where we take a very strict interpretation of the rules, so I have a few questions/comments:

1. Is there a non-metal/hard plastic material on the bottom of the outrigger legs? I am assuming those legs touch the carpet.

2. Are the outriggers inteded to push against the floor as to transfer weight to the outriggers?

3. If your answer to 2 is not yes, then it looks to me as if you are using the midfield barrier to gain an advantage. The rules referenced earlier in this post seem to address that issue.

As far as the pinning goes, I would be VERY suprised if a team got DQ'd for pinning you if your outriggers are reacting with the midfield barrier. Team 217's interpretation of the rule is that the midfield pipes are there to make it harder to cross the field. Any other use of the barrier is probably illegal.

The argument that you're not touching the barrier until someone pushes you is a pretty weak claim, because it is clear to me that you are straddling the midfield bar for a specific purpose.

Of course, please ignore number 3 if your answer to #2 is yes.

For what it's worth, I think you have an amazing design.

-Paul

Unhappy People Please

Understand this. This is a beatable robot. All robots can be defeated with strategy. Look at Beatty, everyone saw them as undefeatable, and , well, they did win nationals, but they were still beaten in some rounds.

I am very proud of my robot, we put a lot of work into is, as im sure that all of you are proud of your robots. I am NOT saying that this robot is undefeatabe. Gadget is right, everyone worked very hard on what they built in these last six weeks.

Also, i'm sure that there are other robots out there like this. A lot of teams would be wantng to their robots a secret. I think that sharing your robot is a great way to help scouts, as well as provide constructive criticism for our designs.

Once again, i thank everyone for their input, and would like to thank the teams out there that have shared theur designs.

Magnasmific....I've got a question, how exaclty are those arms deployed? I mean, I can't see anything "driving" the arms from the pictures? Transfer of wieght maybe? Also, To my knowledge, you can't have a metal surface come in contact with the field...I hope you have some kind of plastic cap on the "feet" of the arm's final stage!

the first stage of the arms are driven by a cable attached to the window motors. the second set is powered by globe motors, with a worm gear. The final stage is unpowered, except for a gas shock which allows for extra clearance of the plexiglass (not pictured in any photos), and gravity.

Also, on the bottom of the arms, its hard to see from the pictures, there are nylon fittings on all of the bottom of the legs. This eliminates the "hard contact with floor" rule.

We can create a downward force on the arms. This will allow us additional traction. As far as weight transfer goes... yes there will be "weight transfer".

There is a specially designed traction material that will be attached to the bottom of each of the legs.

People, stop arguing over what rules the robot breaks or w/e. That's for the judges to decide. Saying all this now doesn't help as it's AFTER ship. It's more of an insult. It's a great LOOKING robot but till a regional, none of us except on team 68 will know how well it performs or whether the judges/refs will determine it to be perfectly legal.

I think some of the argument comes from teams that considered a limbo block from the HDPE but decided against it due to rule interpretation.

Just like the mousebots last year, many teams were upset by their use because they didn't build one because they interpreted the rules differently. Only a few teams made "LEGAL" tether's, most had a high chance of entanglement but were still given the OK.

ramming by definition cannot be pinning. Ramming is using the power of the bot for repeated strikes. Pinning is using the bot to hold something against a fixed object
