It has been a busy week for the Machine-Human Alliance. Sorry! The Human-Machine Alliance. Humans will always take precedence. First there was the deployment of South Korea's autonomous jellyfish-killing aquatic robot swarm. Now, in a completely unrelated development, the engineers at Boston Dynamics—working on behalf of the Defense Advanced Research Projects Agency—have released video of the WildCat, an untethered version of their quadrupedal Cheetah robot, capable of standing and running freely under its own power.
