Team 2992 - 30 pt Climber - Top target dumper

[sircedric4]

We have completed enough of our robot to finally showcase how we are gonna climb to 30 pts and dump frisbees on the top for 20 pts.

This week we will be finishing the wiring and plumbing and doing the final Cg adjustments to make it work.

To begin, this link takes you to a simulation we performed on the CAD robot to show everyone how we expect it to climb.

Our other video shows us doing the first 2 levels to make sure that the robot, as built, performed as required. You will notice weight cupcakes zip tied all over the robot to make sure our robot is at the proper weight and Cg.

We plan to have the robot climbing under its own brains this weekend and when we get video of that, I will post it to this topic.

Enjoy! We look forward to your comments and questions.

...wow....speechless. If you can get that to do it fully on its own it will be beautiful to see. How far are you guys along on the dumper part and does it stay legal?

Very very cool. Hope to see final video of it scoring soon.

The dumper is done and just needs plumbing. This weekend will include a test of how it performs. This weekend is gonna be our full up system test if we can keep from running into show stoppers.

It easily meets the geometry and weight rules and stays within the 54" cylinder. All our valves, tanks, pistons and such are rated 150 psi working. As far as we can see from reading the rules it should stay legal. :-)

So is this gonna be your team's thing? Climb to 30 and then dump 4 or will you be able to score other discs before climbing?

We had a strategy meeting at the beginning of our season and discussed the maximum points we could deliver given our limited resources. During that strategy meeting we figured a consistent 50 pt robot would be a good alliance teammate for nearly every game. The rest of the time we will be playing defense.

We have been focusing on reliability and robustness because the climb and dump is such an all or nothing approach.

This year has been very exciting for us. My fellow mentor and I personally like these years where it is extremely difficult to do it all and forces specialization.

For instance during Rack and Roll we concentrated on the ramps for our robot and were very happy with that consistent 60 pts.

They won't need to score other discs before climbing...They'll be a sure bet for a third pick, at least.

Great Job!!

This was essentially our strategy for almost the first half of build, but we chickened out. Great job! I think you will be a first round pick at every event you attend, and definitely a second round at Champs, if you have the climb and dump consistent enough.

Heck, 50 points per match, they may seed #1 at every regional they attend.

Why dump only 4?

Take 2x 3pt penalties and score the last two colored discs too. Still a net gain of 4 points.

It was designed during week one when it still had to stay inside a 54" vertical cylinder. It easily stayed inside the original 54" vertical cylinder, including the "swing" from one bar to the next. The rule change at the end of week one allowing the cylinder to stay "robot oriented" didn't affect us.

This is an excellent strategy. I wasn't understanding why you would go with such a complicated dumper until I read this, and now it seems brilliant. Can't wait to see all the systems in action together!

The risk is a bit higher than that according to this Q&A:

There's a potential yellow or red card involved with this strategy.

One of our mentors brought up a design that could have looked exactly like that! Hope it works out for you

Have you calculated how long it will take to fill your tanks needed air volume between matches (using only one legal compressor) and how long the climb will take? Turnaround can be 10 minutes or less during elims...
