Can it work with 2.0?

[35000vr]

i tried it with mindstorms nxt 2.0 and it worked for me

[LEGOLUVSU]

DAMN

[TGHstudio]

niced !

[maskedscientist]

i wish a company would make a standalone product to do this.

[demofactory]

That's a great unit. I would recommend an edge guide on the side of the unit. As it follows the edge of the box, it would ensure straight lines of travel. You think outside of the box! Thanks for posting!

[bigdestroyingrobot]

could i borrow that for math class

[milchschnitte161]

Do all your instructions also work at mindstorm nxt 2.0 ?

[nxtprograms]

Not really, see the home page and the help page for more info.

[ReDFoX2200]

nice work

[BaselXXX]

Great, but I think it would work better if you strip the tire from the wheel for two reasons: the wheel wouldn't change radius at all, and to insure a straight line when passing it over the surface

[nxtprograms]

You could try that, but I don't think you would get enough friction on most surfaces.

[BaselXXX]

Good point.

Well, I guess I can also try and use the two thin wheels with the thin rubber tire. I'll check and see.

[rerere284]

yep.

and it wouldn't record all the length.

[Drummerke1995]

O, offcourse! silly me... thanks for your very fast response!

[Drummerke1995]

mayby cubik cm would be nice...

I like that alot!

[nxtprograms]

Cubic cm is there as "cc". So divide that by 1000 and you get liters, etc.

[chanphillip]

Great idea!

[AnimatorDude1122]

very handy! i like it! =)

[nxtbuilder]

good programing!

[Carbon1700]

I just thinked.

When you press down the wheel, it will change shape, and the numbers wouldn't be correct.

I'm right?

[nxtprograms]

Interesting you would ask that, I actually tested that for another project I was working on. Actually, it doesn't change by much, because although the shape (and rotation radius) changes when you squish the tire, the total circumference doesn't change much, which is what matters. In my tests, squishing it so much that the radius decreased by 25% (pressing really hard) only changes the tire circumference by 6%. This is quite the brain teaser if you start really thinking about it...

[shadowslayer81]

or you could just make the tire's harder.... go simplisity!

[Carbon1700]

I have built this one, and im using a bigger but harder tire.

I have calculated out the diameter of the tire and then i programmed it to work properly myself (getting better at programming now!)

[veikko95]

pretty cool... but im still waiting for something bigger...

[egoistilyas]

thats is very cool...

[paulnunn]

Thats is so cool yay first comment
