"Some day in the not-too-distant future, an autonomous delivery van may pull up in front of your house. A bipedal robot will then step out, and carry a package to your front door. That scenario is envisioned by Jonathan Hurst, an associate professor of robotics at Oregon State University, and chief technology officer of spin-off company Agility Robotics. To that end, his group has developed an ostrich-like two-legged walking robot … and it's called Cassie."

"BigDog is a dynamically stable quadruped robot created in 2005 by Boston Dynamics with Foster-Miller, the NASA Jet Propulsion Laboratory, and the Harvard University Concord Field Station.[1] It was funded by DARPA, but the project was shelved after the BigDog was deemed too loud for combat.[2]"
