Sometimes you'd think that it's "tests" like these that would have robots rebelling against their cruel human masters in the future. But for now, however, while they still don't have the intelligence to do so, we will keep on poking them. For Science! With DARPA's Robotics Challenge, the most grueling display of non-combative robot resilience, nearing its finals next month, teams like the Institute of Human and Machine Cognition (IHMC) are pushing their Atlas robot to the limit, making sure they don't fall. Or don't push back.
