Researchers at the Oregon State University (OSU) Dynamic Robotics Laboratory have showcased the latest in the ATRIAS series of robots, a bipedal machine based on the movements of birds rather than humans. This particular approach has enabled the robot to overcome obstacles, a major step in the journey towards running around in the wild.
According to the OSU project documentation, the ATRIAS series is “designed to test and demonstrate theoretical concepts for efficient and agile locomotion,” with the ultimate goal of “walking and running outside in rough terrain.” Researchers hope to accomplish this through the use of the “spring-mass” model of movement, which can allow robots to “both walk and run with remarkable energy economy.”
“When this robot gets up to speed for walking...it will be the fastest bipedal robot in the world,” Jonathan Hurst, an associate professor at the OSU College of Engineering, told reporters.
ATRIAS has legs made of lightweight carbon-fiber, mounted to elastic fiberglass springs that act both as a suspension and a means of mechanical energy storage, allowing the robot to run around on a fairly small battery charge.
There are two other ATRIAS robot operations in the US – at the University of Michigan and Carnegie Mellon University – but the OSU robot has captured all the media attention, partly because it has its own Twitter account.
Hello World! Shall we play a game? #RobotClichés

Earlier this week, a video of the robot surviving a barrage of dodgeballs was accompanied with a tweet: “The humans are just amusing themselves now. Not my favorite hobby, to be honest.”
And last week, a test saw ATRIAS keep its balance while getting kicked. “Now I’m being kicked. Humans: Time to spread robot abuse awareness.”
Development of the ATRIAS line began in 2009. It is backed by the International Human Frontier Science Program Organization (HFSPO) and DARPA, a US government outfit with the mission of “creating breakthrough technologies for national security.”
DARPA is also funding other robot projects, including the four-legged robot dog “Spot,” showcased last month by the Google-owned Boston Dynamics.
According to the OSU robotics team, ATRIAS will appear for a live outdoor demonstration at the DARPA Robotics Challenge, scheduled for June 5-6 in Pomona, California.
