With a top speed of 4mph, the poorly named Starship moves slightly faster than walking humans. Inside, it can carry about 20 pounds, or two bags of groceries. Ideally, it will deliver them in 5 to 30 minutes, or about the same time as a walk to the grocery store itself. Its cargo will be stored inside the hollow compartment of the robot’s body. The lock on the compartment will only open with the customer’s mobile app.
