Core Viewpoint - The world's first humanoid robot half marathon took place in Beijing, showcasing significant advancements in humanoid robot technology, particularly with the robot TianGong Ultra, which completed the race without remote control and set a new world record [2][3][4][6]. Group 1: Event Overview - The half marathon featured 20 humanoid robots competing alongside 12,000 human participants, highlighting the growing interest and capabilities in humanoid robotics [3]. - TianGong Ultra, developed by the Beijing Humanoid Robot Innovation Center, completed the 21-kilometer race in 2 hours, 40 minutes, and 42 seconds, marking a historic achievement in the field [3][4]. Group 2: Technical Challenges and Solutions - TianGong Ultra's design posed multiple technical challenges due to its full-size stature of 1.8 meters and weight of 55 kg, requiring advanced solutions in stability, joint drive systems, and energy management [7][9][11]. - The robot utilized a high-power integrated joint system to manage the significant weight and prevent overheating, achieving industrial-grade durability during the race [12][14]. - Innovations in the robot's leg structure, including a soft-hard coupling design, allowed for effective shock absorption and energy storage, enhancing its running capabilities [16][17]. Group 3: Intelligent Control Systems - TianGong Ultra employs a dual-brain intelligent control system, with a "large brain" for high-level task planning and environmental perception, and a "small brain" for precise movement control and dynamic balance [18][20]. - The robot's ability to adapt to complex environments is enhanced by a 3D semantic map and advanced algorithms that allow for real-time navigation and obstacle avoidance [19][22]. Group 4: Market Implications - The success of TianGong Ultra in the half marathon underscores the necessity of full-size humanoid robots for practical applications in various industries, as most existing infrastructure is designed around adult human dimensions [24][25]. - The trend towards full-size humanoid robots is being recognized globally, with companies like Tesla and Amazon also developing robots that meet similar size standards for operational efficiency [28]. - The advancements demonstrated by TianGong Ultra suggest a potential shift towards large-scale production and commercialization of humanoid robots, with 2025 being highlighted as a pivotal year for the industry [31].
