Agility Robotics, a spin-off of Oregon State University, is officially announcing a shiny new bipedal robot named Cassie.

Cassie is a dynamic walker, meaning that it walks much more like humans do than most of the carefully plodding bipedal robots we're used to seeing.

This makes it better at handling the kind of diverse and complex terrain that we walk over all the time without even thinking, a talent that's going to be mandatory for robots that want to tackle the different environments and situations that they'll need to master to be actually useful around people.

In addition to search-and-rescue and disaster relief, Agility Robotics has one particular environment and situation in mind: They want Cassie to be scampering up your steps to deliver packages to your front door.
