Multiple rolling interfaces, each following its own precisely specified motion, stacked into one system — a motion no legacy mechanism can produce.
Rolling interfaces combined in sequence, each contributing its own motion to the whole.
No meshing teeth and no sliding — the raceway geometry is solved so contact stays rolling.
Motions that legacy mechanisms cannot achieve, coordinated by rolling contact alone.
Animation is a kinematic simulation of the rolling interfaces. Efficiency figures quoted elsewhere on this site are targets, pending physical validation.
