ANYmal is a quadrupedal robot designed for autonomous operation in challenging environments. Driven by special compliant and precisely torque controllable actuators, the system is capable of dynamic running and high-mobile climbing. Thanks to incorporated laser sensors and cameras, the robot can perceive its environment to continuously create maps and accurately localize. Based on this information, it can autonomously plan its navigation path and carefully select footholds while walking. Driven by our first real-world application, namely industrial inspection of oil and gas sites, ANYmal carries batteries for more than 2h autonomy and different sensory equipment such as optical and thermal cameras, microphones, gas-detection sensors and active lighting. ANYmal can be used for dangerous inspection work in the mining industry, on oil and gas platforms, to search for earthquake victims or to defuse bombs or mines.
