Re: Truly omnidirectional omniwheels?
I think he wants an "omni"wheel that will roll freely in every single direction except forward/backward. (Thus, the motors will still drive the wheel along one axis.)
With traditional omniwheels you can push them only sideways if the driveshaft isn't moving. With the wheels he's talking about you could still push the wheel at a 45 degree angle with forward being 0 degrees.
It wouldn't have very much traction though, but I think that's the point.
