Core Insights - The gap between human sprinting records and humanoid robot performance is narrowing, with predictions that humanoid robots may surpass Usain Bolt's record in the near future [1][2][6]. Group 1: Humanoid Robot Performance - The best 100-meter sprint time for humanoid robots is currently 21.5 seconds, achieved by the Ultra robot at the World Robot Competition [2]. - The Ultra robot operates autonomously without remote control, showcasing advanced capabilities in complex environment understanding and motion planning [2][3]. - The performance of humanoid robots in sprinting serves as a comprehensive test of both hardware and software capabilities, including stability, reliability, and real-time environmental perception [3][4]. Group 2: Technological Advancements - Improvements in leg control and motion algorithms are becoming a focus for humanoid robot development, with reinforcement learning techniques being employed to enhance running skills [3][8]. - Companies are optimizing various aspects of robot design, including joint durability, structural components, and energy efficiency, to improve running speed and stability [5][6]. Group 3: Energy Consumption Challenges - Humanoid robots face significant energy consumption issues, particularly in maintaining balance and executing dynamic movements, with leg movement accounting for 80-90% of total energy use [7][8]. - Current humanoid robots have limited battery capacity, which restricts their operational time to approximately two and a half hours under full load [7]. - To enhance energy efficiency, strategies include optimizing gait and control to mimic human passive walking and exploring more efficient dual-leg structures [8].
