i will be interested to see if any team attempts to use these because they are MUCH more sophisticated then regular omni wheels.

well, some teams use 4 "standard" omniwheels at each corner at a 45 degree angle. this is exactly the same thing..basically..isnt it? each 'small' roller is contacting the ground at a 45 degree angle from the "forward". and the controls would be the same too. theoretically if there were two robots. exactly the same in every aspect except robot A had "normal" omnis at a 45 degree angle at each corner, and B had these "new?" omnis, and both omnis had the same diameter, and same friction with ground, robots A and B will accelerate exactly the same, push exactly the same, and handle exactly the same.
the reason forklifts dont use normal omnis at a 45 is probably because its just harder to make a forklift that way. well, not harder but more like impractical.. 45 degrees will take up more space than a straight wheel.. but for our robot applications, unless you buy these, machining normal omnis will be much easier than these ones.. and mounting wheels at 45 degrees on a robot is not that hard to do..
hope someone understands me..

yes. unless you're using them as a caster/ ball transfer replacement
