Oregon State University has spun off one of its first businesses, Agility Robotics, focused on legged robotic locomotion and enabling robots to go anywhere people can go. A leading application for this type of mobility is package delivery. The company currently offers a bipedal robot named “Cassie” that can stand, steer, and fall without breaking. The leg configuration of Cassie looks much like an ostrich or other ground-running bird. A 3-degrees-of-freedom hip allows the robot to move its legs forward and backward, side to side, and also rotate them at the same time. “Quite simply, robots with legs can go a lot of places that wheels cannot. This will be the key to deliveries that can be made 24 hours a day, 365 days a year, by a fleet of autonomous vans that pull up to your curb, and an onboard robot that delivers to your doorstep,” says Jonathan Hurst, associate professor of robotics at OSU.
