Mindboards

I received a new batch of Rotacaster Omni-wheels a couple of days ago for testing. They look and function fantastic. And the new Colour Palette, matches that of the LEGO Mindstorms NXT Kits.



The time, money & effort Rotacaster has put into getting these LEGO Technic and Mindstorms Compatible omni-wheels has paid off. The new wheels don't only look great, but the rollers which allow the wheel to move sideways have are very free moving compared to the earlier prototypes I received.


Gone are the hassles I had initially with rollers binding!


A Great Looking Omni-directional Keyring, was also in my consignment!
(Great timming as my Toyota Landcruiser keyring fell apart last week.)

Congratulations Rotacaster on a an amazing piece of engineer, which every serious LEGO fanatic will wont in their spare parts kit!


Rotacaster Omni-wheels make the Ultimate Jockey Wheels: they never ever JAM!

They will look the part on any LEGO Technics Model or Mindstorms Robot.

I ordered some Robacaster wheels a few months back. I received the four wheels, but one was missing the hub. I e-mailed them back, and a few weeks later, I received an empty envelope with a hole in it.



I'm mostly only planning on using three wheels, anyway. So, I gave up.

CREEPY! I'm scared. did someone take out the wheel hubs or what?

I've contacted Rotacaster and they'll handle it. No it is more likely that the envelope got damaged by the hub itself.

LEGO NXT Line Following Articulated Dump Truck preforming Power-slides with the assistance of the new Rotacasters prototypes I received for testing.



As promised a week or so ago, "too put the New Rotacaster Omni-Wheels through their paces".

They where just what I need for the Line-following Articulated Dump Truck I've build developing as part of a Larger On Going Project. The Rotacasters defiantly help the Truck negotiate the tight corners on my test Line-following mat?

Without the Rotacasters fitted to the two rear axles of the truck, the truck is unable to negotiate the tight corners presented to it. With a radius of 150mm (6"), these are really tight corners for the 410mm (1'4") long truck which can only rotate 40° from centre.

These tight corners force the rear of the track to preform a Power-Slide, which with standard LEGO Technic Wheels just doesn't happen! And as a result the truck can't follow the line with ease.
