The first time you see a strange robot walking down your street, it might be delivering a parcel. That's the future envisioned by Ford in a new research project that explores how robots and self-driving cars could work together to deliver groceries, fast food, and more. The robot in question is called Digit, and it stands just over five feet tall. It has a pair of skeletal legs, two arms ending in shapeless nubs, and a sensor array where its head should be. It's the creation of startup Agility Robotics, which has been developing bipedal robots since 2015 when the company was spun out of research from Oregon State University.
