[FTC]: How far is everyone?

[BradMello]

How far are you guys into designing and prototyping?

[Rick TYler]

Robot is done and programming is in progress. At least version 1.0 is done.

[ttldomination]

Robot is done. It can hold 30 wiffle balls and score all of them in the buckets on the side. The intake mechanism is truly the best part.

Our autonomous can clear one ball holder and then score them in the bins that we have.

Enjoy.

[JesseK]

Heh.

We still haven't received 2 of the 4 kits. So the 2 newest of our teams are still in design. A great thing that came out of that though is we have ridiculously awesome spreadsheets for modeled ball trajectories that include wind resistance and backspin. The kids also came up with a great strategy/design combo that has the potential to use as little as four motors on the entire bot, hold 36 balls, and score anywhere they please.

Other than the designs, we're using old parts to prototype shooters.

I would be pretty impressed if i saw some pictures and or videos of these robots in action seen as how they are already complete

Snap that's crazy, we haven't received our new Kits yet at all, we are still trying to come up with ideas because our FRC team is going to start their own FTC team, all us FTC vets are trying to build a good programming base because last year we used NXT-G this year we are going with Robot C. And we have to hurry up SC's competition is in December XP. Last year we had until April and we were the champs i don't know how this year will turn out with 3 teams and all.

My team has something that moves around, and a good prototype ball launcher, but not a whole lot else =D

Does anyone have a good white paper on gear ratios?

[emmell]

Not necessarily specific to TETRIX, but here's a great tutorial on gears, ratios, and more.

Very worthwhile read.

We've used this application to teach gears: http://www.tucows.com/preview/346223?q=GEARS. The version at this Website is free, but they (theoretically at least) have a newer release that costs money.

(Thanks to Jason Brett for finding this.)

We have a chassis done and it moves in driver mode. we need to come up with a ball delivery system. What ideas have any of you all had? We are a rookie team that are a little bit lost.

[FTC G-FORCE]

Ok, because there's 2 or 3 robots that are done, I would love to see some videos. (I look for videos on youtube one time a day) and if you don't want to broadcast the videos, I'm fine with that too. Thanks.

We are getting our kits today and we have a very cool design it mainly collects balls throughout the match the fires them into the off feild goal it the last 30 secs. We can hold up to 30 balls in our hopper.
