Re: Which wheels will you use for your robot this year?
 

haha thats cool. maybe this time you wont have to push us back across the home zone line for more points due to the fact we fell over. We should probably be more than enough to compete with this time around :p

Wheels?!?
Ours is going to hover!

(If I can convince the engineers to do it, and that it is even possible. Not that I would know, that's why I'm on animation)

how about these?

wow, also found some things about AndyMark on thier site as well. http://omconsults.net/Bot/Mecanum.htm

Re: Which wheels will you use for your robot this year?
 

Thats hard to believe because IFI wheels are very well made and they have helped us on our robot numerous times. How were you using them?

Re: Which wheels will you use for your robot this year?
 

We are custom designing and fabricating our wheels. We convinced our local metal shop sponcer to cnc them this year which allows us to make them lighter, stronger, and way better looking :) They go to the shop tonight and should have them tomorrow :D im excited :D

Re: Which wheels will you use for your robot this year?
 

665 is using 4, 7.5" pneumatic wheels we normally use, along with two of the plastic AM omniwheels. The pneumatic wheels work well with a lot of grip, well last year a little to much, we couldn't really turn with the tank drive, but this year we have the omnis and after prototyping a drivetrain like this over the summer, we decided it should work this time with the pneumatic tires.

Are casters allowed?
 

Are casters allowed?

We are planning on using casters in place of the back wheels on our bot...

Does anyone know of any problems of doing this?

Thanks

Re: Are casters allowed?
 

Why yes, casters are allowed, as long as they do not have the potential to damage the playing field (smooth). The problems of using casters makes you a target for beingspun around by other robots since you dont really have any substantial friction there. But if it works for you, then use it.

Re: Which wheels will you use for your robot this year?
 

I like these home-made wheels.

But they were time consuming and needed a material upgrade to improve durability, so this year we'll be going with these COTS wheels.

Custom machined aluminum.
Custom Urethane tread molded directly to wheel.

Re: Which wheels will you use for your robot this year?
 

good wheels...lol

Re: Which wheels will you use for your robot this year?
 

We are using 6 IFI whells as of right now but we might change 2 of them because of scrubbing we still have to test. One of the solutions we have for the scrubbing is to turn the treads over and use the slick side to gain less scrub.

Re: Which wheels will you use for your robot this year?
 

We're using wheels that are like andy marks but we bought them at princess auto. If machined down to make a grove and drilled for the hub they are the 100% exact copy of the andy mark ones

Re: Which wheels will you use for your robot this year?
 

We learned a lot from our drive train disasters from last year. :) This year we are trying out a 6 wheel drive for the first time. 6 6"x1" IFI wheels driven by Andymark two-speeds. All sitting nice and comfy inside a chunk of fiberglass I-beam. :cool:
