➀ Robotics engineers at ETH Zurich have upgraded a quadruped robot, enabling it to climb standard ladders quickly. The robot, ANYMal, has been modified to use robotic paws that can form a hook-like grip. ➁ The team employed reinforcement learning and a simulation with a teacher-student method to train the robot. ➂ The robot achieved a 90% success rate in climbing various ladders in real-world scenarios.
