Walmart receives patent for self-driving carts

(WIAT) — Last week, Walmart was granted a patent for self-driving carts. The carts will be equipped with detachable motors that have sensors and video cameras.

Customers will be able to request a cart using a “user interface device”, potentially a smartphone, and the roaming motors will be able to fetch a cart and bring it to a customer. The system will be able to identify an unattended shopping cart and return it to a docking station.

There is no word yet on when or where Walmart intends to start using the system.
