Since then, robots have fascinated the minds of sci-fi writers and engineers alike. Which brings us to Cassie – the next generation of bipedal robots devised by Oregon State University’s Agility Robotics. Cassie originates from its predecessor ATRIAS. The problem that researchers kept stumbling over when developing ATRIAS was that it contained motors which worked against each other. As a result, this left the robot in being completely inefficient. Cassie, on the other hand, contains steering, feet, and a sealed system, allowing it be both agile and robust.
