[FTC]: Robot Designs
 

Hey guy's I'm with a rookie team, 3750, and I'm wondering on some of the in's and out's of general FTC design. The team and I don't wish to copy anyone's design, but I've been wondering what are general strategies people have like different wheel configurations, utilization of motors (HT and Lego) and servos, attaching different electrical components and the battery pack (This is a big one), as well as what types of mechanisms work for different situations, ect. It would be much appreciated if different teams could provide detailed photos of their robots past and present so that I can investigate these different designs. Although I completely understand for any teams that wish to withhold from presenting present robot designs, but past are appreciated as well.

Thank You

We'll put up some pics of FTC CAD if that helps?

Re: [FTC]: Robot Designs
 

I still need to get the CAD software on my computer, but the CAD drawings should be better if you have them.

Re: [FTC]: Robot Designs
 

this is something a friend and I are working on. Sorry, be we won't be putting up the CAD files any time soon.

Re: [FTC]: Robot Designs
 

that CAD looks really nice what program are you using

Re: [FTC]: Robot Designs
 

That's done by rc_cola1323 using Solidworks. Most content is from 3dcontentcentral

FRC 11 isn't forming any FTC teams this year but RC and I have been working together on designs for his FTC teams

Re: [FTC]: Robot Designs
 

nice looking robot, is your pickup on the same side as your shooter, feeding the barrel from the bottom?

Re: [FTC]: Robot Designs
 

the CAD looks awesome; however i see some possible problems. The wheels wont be stable they need to go through 2 sides of the C channel for it to work otherwise your robot will bend shafts faster and the wheels will be tilted at an angle.

Just my 2 cents about the drive train

Does this work like FRC 148 the Tornado for Lunacy?

Re: [FTC]: Robot Designs
 

Similarly to 148 but we couldn't match its function using the Tetrix stuff. The CAD isn't done yet, obviously, as we're just playing around with stuff for a while now. The shooter is independently driven from the intake and shooter feeder. And I'm not worried at all about the cantilevered shafts bending. If they do, we have more.

Re: [FTC]: Robot Designs
 

Our Atomix team is building a Helix design similar to the Tornado and it works great.

Team #11
Thanks guys, those are some great designs, which will really help us newbies get some fresh ideas for manipulation and shooting.

'Gracious Professionalism' at its best :D

Re: [FTC]: Robot Designs
 

Thanks for the compliment, but again, this is rc_cola1323's design from FRC 1323, I was simply "consulting" with the design.

Oops, I missed that. Great design. RC COLA! and kudos to Team #11 for helping out with the CAD.:)

Re: [FTC]: Robot Designs
 

I have to post something later i want you guys to see. We are doing a helix and we are using a tower of zipties to do it and surprisingly it works.

Re: [FTC]: Robot Designs
 

FTC 369(FRC 623) has created the king of all zip tie trees. There is no comparison to our 700+ zip tie coated piece of pvc pipe. pictures will be up soon.only downside is color(plain white).

Re: [FTC]: Robot Designs
 

Ours looks haharious though we used every size ziptie allowed. fom the micro, to the 2 foot ones.

Re: [FTC]: Robot Designs
 

you cant use two foot zipties. only 11 inchers. my interpretation of the rule is that the initial size of the ziptie is what governs if it is legal or not

Re: [FTC]: Robot Designs
 

Swerve drive would be awesome to do, but it is hard.
In the 2009 game, it was important to have a fast robot so it wouldn't get pinned. Slow Robots in Lunacy were bad.

Re: [FTC]: Robot Designs
 

This is the FTC thread...

Re: [FTC]: Robot Designs
 

We took the 2 footers and trimmed em to fit in the 18x18 limit

Re: [FTC]: Robot Designs
 

Section 4.2<R5>c.22 :
"Non-Metallic Cable ties (also known as Zip Ties) up to 11” in length may be used."

im not sure if your aware of this rule. you seem to not understand that a 2 foot ziptie is illegal. If you cut the ziptie down to 11 inches long it might be legal but i would ask the official rules forum.

Re: [FTC]: Robot Designs
 

It has been asked and answered--shortened 2 footers are not legal. From the official Q&A fourm:

A: Zip ties longer than 11” may not be shortened and used for Robot construction.

We know that basically it was all we had when we were prototyping
