this was my design for a 2" diameter mecanum wheel that i was going to use to make a edu... I mean ROBOVATION! robot.. the tread on the wheels would be handle dip you get at ace hardware.

It certainly looks promising...but I can't help but think, #2-56 is small stuff, even for an Edu-bot!
How have you defined the curvature of the wheel rollers? Fancy math, or estimation?

when you view a circle from a 45 it apears as an elipse to you its realy as simple as that. the rolers are just the oppsite they have the curvature of an elipse witch viewed from a 45 is a perfect circle.
Oh that radius you mean!. sorry this was a print i made for my friend to make i simplified the radius as to not drive him nuts with elipitcal arcs when all he has is manual tools

Lol Tytus believe it or not I still have those. Sry we never got to it someone ran our cnc lathe into the chuck over the summer and we had to order a new one and we just didn't have the time before season started. These actually aren't that bad to machine compared to other designs, they are small however. Were actually prototyping a modified version of a mechaum wheel right now. I'll see if the man doing the Inventor and I can post something on them once the prints are finished. By the way not bad cad work ty.

If you plan on making some of these let me know, i'd be very interested in purchasing some/ hearing how they come out
