Researchers have demonstrated that robots can achieve robust and dynamic locomotion even with low-frequency motion control, executing at speeds as low as 8 Hz. This approach, detailed in an arXiv paper, challenges the conventional idea that higher frequencies are always better for robotic movement. The study shows that low-frequency policies are more resilient to actuation latencies and system dynamics variations, enabling successful sim-to-real transfer without extensive randomization. The robot, an ANYmal C quadruped, achieved a heading velocity of 1.5 m/s and could traverse uneven terrain while resisting external perturbations. AI
