Does it work?

ofcourse it works Tom. I have seen another version of this somewhere else. Looks almost the same. I think Tytus has experimented with these wheels and made sure that if they work or not.

That is sweet. Awesome!

It'd be so cool to build something like that !!

yeah that trully impressive but the question is not will it work. what i wonder is will it stay i one piece without glue?

Where did you see a version like this? (Do you remember? )

Yes, it works. Yes, it stays together just fine. As soon as I finished the computer modelling, I started taking the real things apart, but maybe I'll rebuild it just to show you...

For those wondering if it works, I made a short video.

Please be patient if the less than one MB file takes a minute to download. You're using my 30kbs upstream cable.

Enjoy.

this is real cool. especvially if you can get it working properly when i made wheels like that i found that they are too jumpy to have any sort of grasefull movement from them afterall it is a hexognal wheel rather than a round one. kudos to you if you build it.

What program did you use to model/render that graphic?

For the actual modelling, I used MLCAD. For the rendering I used POV-Ray, but the actual POV-Ray file was generated by L3P (made even easier by the Windows interface to that, L3PAO.)

That's just plain insane. Amazing. Out of this world. Just, wow. The question is though, could I get a FLL team to build it and get it running???

You probably could, but not for the regular season... it takes a lot of parts not in the normal kit, so I don't think you can. Then again, I'm not in FLL. (Hoping to mentor a team this year though! )

The main problem with the current design is a lack of any sensors. I would love to put encoders on all three wheels, but I only have one. (main problem with my current collection) Without sensors, it slightly less of a programming exercise...

How is it controlled? Is there just a random program in there telling it to drive the motors different directions for different amounts of time or is there some sort of remote of what?

Also, does the RCX offer speed control over motors?

The video is a random program. There is a LEGO remote, but it's rather hard to control all three motors at the same time, especially while holding a camera. Now that I have two RCX's, maybe I'll make a more intuitive control.

I am hoping to add some sort of sensors, but how/where/what I'm not sure of yet. (Obviously not to clear on that... )

Yes, it does. The video doesn't show that though.
