Bot Bench I'd Rather Be Building Robots
These are the new Rotacaster wheels that arrived Monday morning. The one with the orange hub has dark grey, soft, very grippy rollers; the wheel with the dark grey hub has slightly harder, orange rollers. These are the latest prototypes and they have undergone some great improvements; the rollers roll more freely and the hubs grip the axels in a more LEGO-like fashion.
If you click on the picture, you’ll be able to see how closely they match the colours of the Technic beams shipped with the NXT kits. Hopefully they will go on sale soon. Please be patient while they sort out some final details; it won’t be long now!
I put 3 different wheels on one my omniwheel frames so you can see the difference between the old prototype (the one on the left) and these new ones:
I really love the new tri-coloured look, I sure hope these are the ones they end putting into production!
Hi Xander,
Have you been able to compare the vibrations these new wheels generate compared to the old ones?

No, I haven’t, that’s a good one. I’ll see about doing some tests in the next few days 🙂
We are confident you will find a big improvement in the ride quality. A very simple test is to put two of the same wheels on a Lego axle and roll across a flat surface and compare the two different sets. Something to remember is when mounting the wheels, they must be supported perpendicular to the running surface. If they are not they will exhibit increased vibration as they will tend to run on one rim. If your rig doesn’t have the rigidity, I’d suggest running two wheels side by side.
where can u buy these?
You can buy them from Rotacaster and pretty soon from the US as well!
bedankt.
Ze zijn wel duur zeg!
Maar ze zijn wel heel erg goed 🙂
I think there is a high performance black on black available, the grip is beyond belief.
