As you can see, the Cheetah's new algorithm improvements make it more agile and able to handle real-life terrain. That's essential if humans want robots in the future to help them carry loads, or explore places that are too dangerous for people, such as the areas surrounding a nuclear disaster. In fact, that's why some labs focus on legged robots, instead of wheeled, which could drive more quickly. The idea is that legs could propel robots over rubble. One day, they may even be able to do so at a runner's pace.
