The self-stop shopping cart (Self-Braking Trolley) is a shopping cart with a collision prevention function created by applying Pre-Collison Assist technology owned by automobile company Ford. The technology was applied in light of the fact that the shopping cart that is always used in the mart has the risk of hitting other customers.
Collision prevention technology is a system that uses a camera and radar to detect vehicles, pedestrians, and bicycles on the road and automatically brakes when the driver does not respond to warnings. The prototype of the auto-stop shopping cart was made as part of this technology promotion, but it has been evaluated as having a good idea. Related information can be found here .
