3rd Party Holonomic Wheels (Omni/Mecanum)

[DrJB]

Contemplating getting some of those, and they do come in many versions. The rotacaster can fit a lego axle, but seems pricey for just that feature. For example, there are other makes, for 1/2 or 1/3 the price of a rotacaster, though they do not come with lego-compatible mounting. Question: Has any one gotten and modified non-rotacaster wheels? Should not be that difficult of a job but wanted to know of prior experiences if any. Of course there is the full-lego options, but those tend to be 'weak'.

What are the full-Lego omniwheels? I would love TLG to make an omniwheel to go with their robotics kits. I have two of the 48mm Rotacaster omniwheels and they are worth the money IMO. I have about 4 of these:

...in my NXT kits at work and they work fine but are quite large. The downside of the Rotacasters is that they are funny size that does not easily match up with standard Lego pieces. It can be done but you need to switch from odd lengths to even lengths to get then to line up.

Here is a link to what I'm considering (OMNI) ... http://www.ebay.com/itm/New-48mm-Omni-Arduino-robot-wheel-for-LEGO-NXT-and-servo-motor-/221284949363?pt=Motors_Car_Truck_Parts_Accessories&hash=item33859c5d73&vxp=mtr ... and the 'full-lego' MECANUM version http://www.eurobricks.com/forum/index.php?showtopic=46945' I know the two are very different, and at this stage have not finalized my 'design' yet.
