Wise Rain Frog on Instagram: "Boston Dynamics has long been at the forefront of legged robotics, and this machine—called the Cheetah or sometimes “WildCat”—is a powerful example of biomechanical engineering meeting raw mechanical force. Powered by a two-stroke go-kart engine, it can reach speeds up to 20 mph, making it one of the fastest untethered legged robots ever built. The robot uses a technique inspired by animals: dynamic bounding. Its legs are independently actuated and precisely control
