Cassie the bipedal robot uses machine learning to complete a 5km jog Cassie the bipedal robot in action Oregon State University Oregon State University Four years is a long time in robotics, especially so for a bipedal robot developed at Oregon State University (OSU) named Cassie. Dreamt up as an agile machine to carry packages from delivery vans to doorsteps, Cassie has recently developed an ability to run, something its developers have now shown off by having it complete what they say is the first 5-km (3.1-mi) jog by a bipedal robot. We first took a look at Cassie the bipedal robot back in 2017, when OSU researchers revealed an ostrich-like machine capable of waddling along at a steady pace. It is based on the team's previously developed Atrias bipedal robot, but featured steering feet and sealed electronics in order to function in the rain and snow and navigate outdoor terrain.
