I received a a new batch of Rotacaster Omni-wheels several weeks ago which look and work fantastic. I gave them a good test run way back on 15th June 2011 and videoed my results. It’s a while, but here they are fitted to a Killough type platform powered by LEGO Mindstorms NXT kit fitted with 3x NXT Motors to drive the Rotacasters.

Christmas arrived early this year for me when the Postman knocked today with a package from Peter McKinnon containing a set of 4x 48mm Rotacasters with the Lego Axel adapters. At this stage these prototypes appear to have been worth every bit of development time they have taken up so far. The softer Durometer Type Rollers on the 48mm wheels, are excellent on timber and vinyl floor surfaces. They also appear to work surprisingly well on carpets as well.

Lego RotacasterAs you are most probably aware, I’ve been working towards having a version of the Rotacaster Omni-wheel available for your Lego Mindstorms kit. With many thanks to Mr. Peter McKinnon, Managing Director of Rotacaster, the company is tooling up to make a run of some 200 wheels which will fit straght on a standard Lego Technic Axle. On the Lego version of the Double Rotacaster 48mm Omni-wheel, the red rollers will be coated with rubber (TPE) to allow for excellent grip on all surfaces. Mr. McKinnen will be in the US from the 19th to the 30th, and depending on timing may bring some of the prototypes back with him for distribution.
