On July 25, NVIDIA and Korea’s KAIST jointly announced an AI research lab focused on physical AI, robotics, and foundation models, marking a shift from pure procurement to joint RD between a leading compute vendor and an academic institution.来源 / SourcesDIGITIMES — Toshiba/Kioxia / TSMC / WIN 报道Semiconductor For You — NVIDIA × KAIST 实验室Design And Reuse — Semiconductor Industry 资讯6、医疗 AI 与手术机器人JJ Ottava × Intuitive Surgical事件概要7 月 25 日强生JJ旗下 Ottava 通用手术机器人平台获 FDA 监管许可进入美国商业化前的关键阶段同日直观医疗Intuitive Surgical披露 Q2 全球达芬奇手术系统出货 350 台刷新单季出货纪录年度装机量向 1500 台关口迈进。强生 Ottava 与达芬奇 SP/Triport 平台的差异化竞争被业内视为 2026 下半年外科手术机器人主战场——前者主打模块化双臂与 OR 通用性后者继续巩固腔镜术式领先与装机基数优势。AI 能力嵌入端两家公司均在 2026 财年加大对术中实时辅助、术后规划与跨术式数据闭环的投入。On July 25, Johnson Johnson’s Ottava general-purpose surgical robotics platform received FDA clearance, entering the key pre-commercialization phase in the U.S. On the same day, Intuitive Surgical reported Q2 global shipments of 350 da Vinci systems — a single-quarter record — pushing the annual install base toward the 1,500-unit threshold. The competitive divergence between JJ Ottava and da Vinci SP/Triport is widely seen as the main battleground in surgical robotics for H2 2026: the former bets on modular dual-arm and OR versatility, while the latter continues to entrench leadership in laparoscopic procedures and installed-base breadth. Both companies significantly expanded 2026 fiscal-year investments in intra-operative real-time assistance, post-op planning, and cross-procedure data flywheels.来源 / SourcesRobotics Intl — JJ / Intuitive Surgical Q2 报道RobotJia — 医疗机器人板块Robotics 24/7 — Surgical Robotics Coverage行业数据速览指标数据备注AMD MI455X 晶体管数3200 亿台积电 N2 工艺AMD MI455X HBM4 容量432 GB12 组 HBM4 堆栈AMD MI455X HBM4 带宽23.3 TB/sCDNA 5 架构AMD MI455X 二级缓存96 MB全局共享设计SK 海力士赴美 IPO 募资265 亿美元外国企业赴美 IPO 历史第二Atoms A 轮融资17 亿美元a16z 领投Etched 二级市场估值103 亿美元推理专用 ASICIntuitive Surgical Q2 出货350 台单季历史新高WIN Semiconductors Q2 营收39% YoY光通信量产驱动Toshiba 持 Kioxia 比例15.1%较上一披露减持 1 个百分点媒体人解读今天的几条主线其实在指向同一个判断AI 产业正在从训练驱动切换到推理驱动 物理 AI 落地。AMD 用 MI455X 把 HBM4 抬上主舞台SK 海力士用 265 亿美元 IPO 和英伟达合作锁死 HBM4 周期二者合力宣告算力侧正式进入下一代内存时代。机器人侧不再是 PPT 阶段AgiBot 递表、Realbotix 进校园、睿尔曼远程操控拉条子说明通用大脑 场景数据闭环开始真正转化为可计费的部署。投融资端的钱在快速向推理专用芯片Etched和具身智能Atoms聚拢。对技术管理者来说这意味着两件事第一未来 12–18 个月的算力采购窗口要看清 HBM4 与推理 ASIC 这两条新增供给曲线第二机器人产品定义要从会走会抓升级到在真实场景里能连续干满一个班次。A few threads from today’s news converge on a single read: the AI industry is shifting from “training-driven” to “inference-driven physical AI deployment.” AMD put HBM4 on the main stage with the MI455X; SK hynix locked in the HBM4 cycle via its $26.5B IPO and expanded NVIDIA partnership — together declaring the next-generation memory era open on the compute side. Robotics has moved past the PPT stage: AgiBot’s filing, Realbotix entering a school, and Realman’s tele-operated noodle-pulling all show that “general brain scenario data flywheel” is converting into billable deployments. Capital is rapidly clustering around inference-dedicated silicon (Etched) and embodied intelligence (Atoms). For tech leaders, this means two things: first, the next 12–18 months of compute procurement must map the new supply curves of HBM4 and inference ASICs; second, robot product definitions must upgrade from “can walk and grasp” to “can complete a full shift continuously in a real scenario.”参考来源英文来源Semiconductor For You — Industry NewsSK hynix NewsroomDIGITIMES — SemiconductorsRobotics Intl — International Robotics NewsRobotics 24/7 — Automation RoboticsHumanoidMagazine — Humanoid Robots NewsKoolerAI — AI NewsRobot.tv — Robotics NewsroomDesign And Reuse — Silicon / ASIC中文来源RobotJia 机器人之家 — 全球机器人资讯SK 海力士全球新闻中心DIGITIMES 中文版本文内容综合整理自上述公开信息来源媒体人解读仅代表个人观点仅供参考。作者署名刘一说 ️发布日期2026年7月27日
