Core Viewpoint - The article emphasizes that lightweight design and low power consumption are critical for enhancing the battery life of humanoid robots, as demonstrated in the recent humanoid robot half marathon where battery endurance was a central challenge [2][3][9]. Group 1: Event Overview - The first humanoid robot half marathon took place, highlighting the challenge of battery endurance, with only one robot completing the race without a battery change [2]. - The "Walker II" robot from Shanghai Zhuoyide achieved third place, showcasing a single charge endurance of 6 hours, sufficient for over 30 kilometers [2][3]. Group 2: Technological Insights - The success of "Walker II" was attributed to innovative structural design and control strategies that achieved significant weight reduction and energy efficiency, weighing only 28 kg compared to competitors [3]. - The champion robot, "Tiangong Ultra," faced limitations with a runtime of 2 hours and 40 minutes, requiring a battery change during the race, illustrating the current challenges in battery technology [4]. Group 3: Battery Technology Developments - Battery manufacturers are exploring various technological upgrades, including higher energy density materials to enhance the capacity of cylindrical cells, with examples like the 21700-5.0AH battery achieving over 270Wh/kg [6]. - Solid-state battery technology is being pursued, with companies like GAC Group planning to launch humanoid robots with solid-state batteries that promise 6 hours of runtime and an 80% reduction in energy consumption [7]. Group 4: Industry Collaboration and Future Outlook - The article suggests that improving overall endurance requires close collaboration between battery manufacturers and robot makers, with market expectations for humanoid robots to achieve 8 to 10 hours of runtime for basic applications [9]. - The marathon highlighted the technological shortcomings related to battery endurance, potentially accelerating innovation in structural design, material selection, and algorithm optimization within the industry [9].

摘要 轻量化、低功耗是关键。 上周末，全球首场人形机器人半程马拉松赛举行，这场约 21 公里的赛事将行业的目光聚焦于一个 核心挑战：电池续航能力。 机器人要么需要极长的单次充电续航，要么必须依赖中途更换电池。事实证明，在 20 支参赛队伍 中，仅有一款机器人能够在不更换电池的情况下，依靠双腿自主行走完成全程。 实现这一突破的是由上海卓益得机器人有限公司（技术核心源自上海理工大学）研发的 "行者二 号"机器人， 该机器人最终获得比赛季军， 其官方数据显示单次充电续航时间可达 6 小时，足以支持行走超过 30 公里。 值得注意的是， "行者二号"的成功并非依赖于电池能量密度的突破。 其研发团队透露， 关键在于通过创新的结构设计和控制策略，实现显著的轻量化和能效提升。该 机器人身高 1.70 米，整机重量仅为 28 公斤。 作为对比，获得冠军的 "天工 Ultra "身高 1.8 米，体重达 55 公斤；亚军"小顽童 N2 "身高 1.2 米，体重 30 公斤。 卓益得的技术路径显示，突破续航瓶颈不仅依赖于电池技术的进步，更需要机器人本体设计的系统 性优化。 该公司同时还采用了 创新的绳驱动技术 ，允许多个电机根据 ...
