Oregon State University has released a promotional video for Cassie, their bipedal robot. The slick video explains how the talented engineering team from Agility Robotics company (AR) developed Cassie. Agility Robotics is a spin-off business from the university's college.

Co-founder of AR Jonathan Hurst explains the colleges push towards advanced robotics. “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.”

Cassie can stand, walk, trot, steer, and take a pretty good fall without breaking. It's a highly developed version of robots previously developed inside the college. To get Cassie so advanced the team had to start from scratch developing much of the technology in-house, even going as far as to build their own lithium battery systems.

“Our previous robot, ATRIAS, had motors that would work against each other, which was inefficient,” Hurst said. “With Cassie, we’ve fixed this problem and added steering, feet, and a sealed system, so it will work outdoors in the rain and snow as we continue with our controller testing.”

Despite the fact Cassie's designers say they weren't deliberately taking design cues from nature, Cassie's final form looks remarkably like the leg of a large agile animal. Cassie was built thanks to a 16-month, $1 million grant from the Advanced Research Projects Agency of the U.S. Department of Defense, and even though development is still continuing, Cassie is already one of the leading innovations in the world of legged robotics.
