人形机器人:技术迭代方向展望 - 2025 年中金公司中期 投资策略会 20250630 摘要 通用机器人需具备多地形适应性和灵巧操作能力,人形结构更适应人类 环境。操作能力是应用价值上限,硬件配置需与通用能力等级匹配。 训练通用机器人需算法、数据、硬件协同,通过采集数据建立观测与输 出的映射关系,实现广泛应用,但构建通用模型面临挑战。 触觉传感器对精细操作至关重要,高分辨率、多维度、高频率的触觉传 感器是机器人实现类似人类灵巧性的关键。 呆萌机器人光学式触觉传感器具有高分辨率(每平方厘米 4 万个点), 可精准感知物体形貌及切向力,对温度不敏感但力敏感度极高。 呆萌推出以人为中心的数据采集设备,捕捉视觉、手部触觉及手臂运动, 更真实反映人类操作,提升视觉、触觉、语言及动作模型训练效果,成 功率从 50%提升到 80%以上。 引入触觉传感器可大幅降低机器人训练成本。达到 80%以上成功率,无 触觉传感器需约 5 万次数据采集,成本约 15 万元,而有触觉传感器只 需 100 次,成本仅 300 元。 推动机器人通用化落地需加强硬件(高质量触觉传感器、灵巧手)、数 据(以人为中心的数据采集)和算法(触觉良好表征 ...
不做整机,戴盟机器人发布具身智能全链路解决方案卡位上游核心赛道|智能涌现
Core Insights - The company Daemon Robotics, based in Shenzhen, launched three new products: the tactile sensor DM-Tac W, the multi-dimensional tactile perception dexterous hand DM-Hand1, and the portable wearable remote operation data collection system DM-EXton, establishing a full-link solution for embodied intelligence data training [1][4] Product Development - Daemon's research on tactile sensors has evolved over eight years, originating from a collaboration between its chief scientist Wang Yu and MIT's Alberto Rodriguez, leading to a unique high-resolution tactile perception technology that does not rely on tricolor light [2][3] - The DM-Tac W and DM-Hand1 products feature a significant advancement in tactile sensor technology, with a density of 40,000 perception units per square centimeter, vastly exceeding traditional tactile sensors [3] Market Positioning - Daemon Robotics aims to carve out a niche in the market by focusing on tactile perception technology rather than competing in the complete machine sector, positioning itself as a solution provider for downstream manufacturers [5][6] - The company has secured significant funding, completing multiple rounds of financing totaling over hundreds of millions, which will support its supply chain stability and production capabilities [6] Technological Advancements - The DM-EXton device weighs 2.5 kg and features 54 degrees of freedom, with a data collection frequency exceeding 800 Hz, enabling instantaneous response and wireless connectivity up to 30 meters [4] - Daemon has achieved a breakthrough by reducing the thickness of its sensors from several centimeters to a few millimeters, allowing deployment in bio-inspired dexterous fingertips [2]
