I posted this description with the picture (repeating here for convenience):

Rollers are 3/4" diameter 60A polyurethane mounted on 3/16" inner diameter bronze bearings which roll on dowel pins. Effective diameter over the rollers is 4.8 inch. Weight as shown including aluminum hub, roller bearing, and 30 tooth schedule 40 steel sprocket is 1.75 lb. We plan to build a holonomic drivetrain using four of these wheels and demonstrate it at St. Louis Regional Fall training camp in November.

Yeah, Steve, we need to get moving. I have a few more parts made, some gears and pinions, shafts, bushings,... but the chassis rails and other structural elements are still in work. PM or email me so we can arrange time to meet.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
