How a Hidden Magnet Steers a Sushi Carrier
The trick is to transfer motion through the track’s surface. A motor moves a magnet beneath the route, and magnetic attraction pulls a matching magnet built into the carrier above it. The carrier’s wheels roll along the track, while the concealed magnetic force supplies the push.
Because the driving parts stay underneath, there is no exposed chain or arm reaching up to grip each tray. The route itself constrains where the carrier can go: as the lower magnet follows the track, the sushi carrier follows above it.
A Small Transport System With a Specific Job
This arrangement is useful for a compact, repeatable journey around a restaurant. It can move individual orders without requiring staff to steer each one, while keeping the moving mechanism out of sight and away from the food. The carrier still needs a track and a reliable connection between its magnet and the drive below; it is not floating freely or navigating on its own.
That makes the system less like a miniature boat and more like a conveyor whose force passes through the tabletop. The visible tray glides along, but its route is being controlled from beneath the surface.
