Robot Legs Finish 5K In Under An Hour On A Single Charge

This is a video of Cassie, a pair of robotic legs (and nothing else) developed by Agility Robotics, successfully running 5K in just over 53 minutes (running at around ~5.7km/h or 3.5MPH) and on a single battery charge. Not bad. For reference, the only way I’m finishing a 5K is if the paramedics roll me the remaining 4.5K’s across the finish line on a stretcher before dumping my body in front of a storm sewer because “Stop, just leave me here for the Ninja Turtles to find, I don’t have insurance.”
