Ford Motor Co. teamed up with Agility Robotics to explore doorstep package delivery from autonomous vehicles through robots.

A two-legged robot designed by Agility Robotics, named Digit, can grab a package from a Ford self-driving car and deliver it at the doorstep, said Ken Washington, Ford's chief technology officer.

The robot can walk through obstacles, climb stairs and carry packages that weigh up to 40 pounds.

Digit will have LiDAR and stereo cameras for better navigation. In addition, the autonomous vehicle will share data, such as the best pathway to the final destination, to the robot.

In 2018, the Michigan-based automaker partnered with retail giant Walmart Inc. to explore the delivery of groceries and other consumer goods with autonomous vehicles. Ford expects to launch the self-driving cars commercially in the U.S. in 2021.
