Walmart wants to spoil its customers with self-driving carts.

The U.S. government granted the retail giant a patent last week indicating the company is planning to roll out a system that allows shopping carts to drive themselves.

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 the customer.

According to the filing, the system will also be able to identify an unattended shopping cart and return it to a docking station.

No word yet on when or where Walmart begins to start using the system.
