Rotacaster Omni-wheel Grip Tests

I received a parcel from Rotacaster Pty. Ltd. a fortnight ago which contained a new set of4x Rotacasters with the new Black Hub-centres and S55A Hardness type Orange Rollers and a set of 3x Rotacasters with the new Black Hub-centres and S45A Hardness type rollers. The S45A’s roller colour is a perfect match for Lego’s “Dark Bluish Gray” colour scheme.
I was excited about testing the new wheels using softer durometer materials on the rollers. The S45A do provide better traction, which should be especially good for lighter robots. The S45A compound is very similar to the white oblong type pencil rubbers.

Peter McKinnon from Rotacaster sent some photographs of the prototypes today of the insert bushes with the Lego cross axle bore.
