Big Lego® wheels with a tread which is a
loose-fitting 'negative' of the Lego stud
pattern, so as to give Lego vehicles a smooth
ride when traversing Lego baseplates.

Maybe this type of track would fit the bill? [Jinbish, Dec 06 2007]

Nice [+]. You could also use them to attach lego bricks to the tyres to make something that can go down steps. |
|
| |
The road area of Lego base plates (if the baseplate has a road area) is already smooth, so as long as you don't do any off-roading, it's a smooth ride anyway... and with the described tires, you can only travel in strait lines in the x and y axes. |
|
| |
If the depressions are small enough for Lego pieces to attach to them, then it will be very difficult for the wheels to roll on the Lego surface. |
|
| |
Yes, this is aimed at off-roading (think of the green baseplates with studs all over, rather than the grey "urban" baseplates with road markings and smooth bits) and the anti-studs defintely have to be 'loose-fitting' so I'm afraid [marklar]'s variation won't work. |
|
| |
If it's off-roading then it's supposed to be bumpy. |
|
| |
Can't you just buy a car with better suspension? |
|
| |
No fair, I want to put legs on the wheels. And how am I supposed to complete my model of an auto shop with a big rotating tyre on the roof? |
|
| |
OK, I'd better explain exactly why I want a smooth ride across a Lego baseplate. I need to have a
mini-DV video camera mounted on a Lego platform which can move smoothly across a Lego baseplate for tracking shots. The shot doesn't allow for the building of rails or a tiled surface. |
|
| |
The anti-studs might not provide the smooth ride if they are constantly pairing with the studs {later: as [BJS] notes}. |
|
| |
I suggest that you want a set of caterpillar tracks (for cogs or wheels) that are sufficiently long (linky). |
|
| |
If your wheels were thin enough they would ride smoothly between the studs. Should work on a diagonal as well. |
|
| |
Hmm... I wonder if there's something that could be done with a large sphere with lots of anti-studs on it... |
|
| |
[hippo], I bet you could build something using superglue and numerous cut-up toothbrush heads. The bristles should adapt to the surface fairly nicely. |
|

//mini-DV video camera .. Lego .. tracking shots//
Sounds interesting, [hippo]. Stop-motion animation or real-time movie-making? |
|
| |
It's stop-motion: DV camera connected to my iMac, running iStopMotion (see link - this is a great bit of software), and iMovie. I'm doing a test film at the moment to get used to the technique. I'll see if I can post it somewhere when it's finished. |
|
| |
I thought it was designed to run over the little Manly Man LEGO men. |
|
| |
//If your wheels were thin enough// |
|
| |
I seem to remember a lego train, with wheels which rested on narrow edges. Maybe they would do the trick, provided that your vehicle is guaranteed to drive *very* straight. |
