The Omnimotion XY is a mechatronic device from Dr. Lu’s research group at the Precision Mechatronics Laboratory. From the video description, the “Omnimotion-XY shown here is a magnetically-levitated planar motion stage. All 6 degrees of freedom (DOF) motion are achieved by one motor, which is free of force ripples or cogging. There is no need to supply electricity or pressurized air to the moving stage. The planar motion stroke can range from cm to m level without much complexity difference. Its non-contact bearing-less features make it very suitable for applications requiring high speed, high acceleration, high vacuum, or high precision in one to six DOF motion.”
