🌅 導言：從數位智能到物理世界的跨越
在過去十年，AI 的爆炸性增長幾乎完全發生在「數位世界」——大型語言模型可以生成複雜文本，擴散模型可以創建照片級真實的圖像，推理模型可以解決複雜的數學問題。但所有這些能力都被限制在螢幕之內——AI 無法移動一個箱子、擰緊一顆螺絲、或在倉庫中挑選物品。
Physical AI 恰恰是為了跨越這道鴻溝而生的——使 AI 不僅能「思考」，還能「行動」；不再只是處理 token 和像素，而是直接操縱物理世界中的物體、工具和環境。
NVIDIA CEO Jensen Huang 在 2025 CES 開幕演講中將 Physical AI 定義為「理解物理法則並與物理世界交互的 AI 系統」，並宣布這是 NVIDIA 未十年戰略的核心。這不是虛言壯語——從 Isaac 機器人平台、Omniverse 數位雙胞胎引擎，到專為機器人設計的 Jetson Thor SoC，NVIDIA 正在構建完整的 Physical AI 技術棧。
🔬 核心技術突破：Robot Foundation Models
從指令到行動的質的飛躍
Robot Foundation Models 是 Physical AI 加速部署的關鍵驅動力。最典型的代表是 RT-2（Vision-Language-Action Models）和類似的 Vision-Language-Action (VLA) 模型。
RT-2：首次實現自然語言控制
RT-2 模型首次實現了「用自然語言指令完成未見過任務」的突破：
- 端到端語言-視覺-動作能力：RT-2 結合了大型語言模型（LLM）、視覺語言模型（VLM）和機器人控制器，所有這些功能都在單一神經網絡中實現
- 網規模知識遷移：通過從互聯網學習的 Web 知識遷移到機器人控制，使機器人能夠理解複雜的空間關係和工具使用
- 鏈式思考推理：RT-2 首先輸出幾步自然語言推理步驟，然後輸出動作 token，展示了完全集成的 VLA 模型的潛力
這意味著，機器人第一次能夠通過自然語言理解任務，並生成相應的動作序列，而不需要為每個任務訓練專用模型。
Open X-Embodiment 數據集
Open X-Embodiment 數據集讓跨機器人遷移學習成為可能。通過在多個機器人平台上的大量任務數據上進行預訓練，模型可以快速適應新平台和新任務，大幅縮短訓練時間。
🎮 NVIDIA Isaac 平台：1000x 訓練加速
數位雙胞胎：從概念到部署的縮短
NVIDIA Isaac 平台是 Physical AI 技術棧的核心組成部分，其關鍵技術包括：
- GPU 加速模擬：在數位雙胞胎環境中訓練機器人策略，訓練速度達到現實世界的 1000 倍
- Omniverse 數位雙胞胎引擎：提供精確的物理模擬，包括重力、摩擦力、碰撞等物理法則
- Jetson Thor SoC：專為機器人設計的系統級芯片，提供高算力低功耗的計算能力
這意味著，開發者可以在虛擬環境中進行數千次訓練迭代，而不需要花費數月時間在真實環境中測試。訓練-部署週期從「數月」縮短到「數天」甚至「數小時」。

🌅 Introduction: The leap from digital intelligence to the physical world
Over the past decade, the explosive growth of AI has occurred almost entirely in the “digital world”—large language models can generate complex text, diffusion models can create photorealistic images, and inference models can solve complex mathematical problems. But all of these abilities are limited to the screen—the AI can’t move a box, tighten a screw, or pick items in a warehouse.
Physical AI was born precisely to bridge this gap - enabling AI to not only “think” but also “act”; it no longer just processes tokens and pixels, but directly manipulates objects, tools and environments in the physical world.
In his opening speech at 2025 CES, NVIDIA CEO Jensen Huang defined Physical AI as “an AI system that understands physical laws and interacts with the physical world” and announced that this is the core of NVIDIA’s strategy for the next ten years. That’s no lie—from the Isaac robotics platform, to the Omniverse digital twin engine, to the Jetson Thor SoC designed specifically for robotics, NVIDIA is building a complete Physical AI technology stack.
🔬 Core technology breakthrough: Robot Foundation Models
A qualitative leap from instructions to actions
Robot Foundation Models are a key driver of accelerated deployment of Physical AI. The most typical representatives are RT-2 (Vision-Language-Action Models) and similar Vision-Language-Action (VLA) models.
RT-2: First implementation of natural language control
The RT-2 model achieved the breakthrough of “using natural language instructions to complete unseen tasks” for the first time:
- End-to-end Language-Visual-Action Capabilities: RT-2 combines a large language model (LLM), a visual language model (VLM), and a robot controller, all implemented in a single neural network
- Web-scale knowledge transfer: By transferring Web knowledge learned from the Internet to robot control, the robot can understand complex spatial relationships and tool usage
- Chained Thinking Reasoning: RT-2 first outputs several natural language reasoning steps, and then outputs action tokens, demonstrating the potential of a fully integrated VLA model
This means that for the first time, robots can understand tasks through natural language and generate corresponding action sequences without the need to train dedicated models for each task.
Open X-Embodiment Dataset
The Open X-Embodiment dataset enables transfer learning across robots. By pre-training on a large amount of task data on multiple robot platforms, the model can quickly adapt to new platforms and tasks, significantly reducing training time.
🎮 NVIDIA Isaac Platform: 1000x training acceleration
Digital Twins: From Concept to Deployment Shortened
The NVIDIA Isaac platform is a core component of the Physical AI technology stack. Its key technologies include:
- GPU Accelerated Simulation: Train robot strategies in a digital twin environment 1000 times faster than in the real world
- Omniverse Digital Twin Engine: Provides accurate physical simulation, including gravity, friction, collision and other physical laws
- Jetson Thor SoC: A system-on-chip specially designed for robots, providing high computing power and low power consumption computing capabilities
This means developers can run thousands of training iterations in a virtual environment instead of spending months testing in a real environment. The training-deployment cycle is shortened from “months” to “days” or even “hours”.
Actual case: BMW South Carolina factory
In a 2025 pilot at BMW’s South Carolina plant, Figure 02 successfully accomplished the following tasks:
- Body classification
- Item transportation
- put operations on hold
- Run continuously for more than 8 hours
This verifies the practical feasibility of language-driven robots.
🤖 Humanoid robots: from laboratory to commercialization
Figure 02: Language-driven robot
Figure AI is the most funded humanoid robotics startup in 2024-2025, with investors including OpenAI, Microsoft, NVIDIA and Jeff Bezos.
Technical advantages of Figure 02:
- OpenAI Deep Integration: built-in multi-modal model based on GPT architecture
- Natural language task instructions: Receive task instructions through language (such as “Put the red box on the third shelf”)
- Real-time Voice Collaboration: Communicate in real-time via voice with human colleagues
- 16 DOF Hands: Each hand can independently control 8 joints
- 20kg payload: enough to move most industrial items
- 5 hours of battery life: supports continuous work
Key Specs: Height 167cm, weight 60kg, fine manipulation capabilities (Dexterous Hand v4 can handle operations that require precise force control, such as assembling tiny electronic components or handling fragile items).
Tesla Optimus: Making genes at scale
Tesla Optimus’ greatest strength lies not in any single technology, but in its mass-manufacturing DNA:
- Gen 2 Design: Based on the successful experience of the first generation, the mechanical design and control system are optimized
- Commercial Pilot: Commercial pilots have been conducted in logistics warehousing and manufacturing environments
- Cost Advantage: Reduce the cost of general-purpose robots through mass production
Market Forecast: $38 billion by 2035
Goldman Sachs estimates that the humanoid robot market will reach $38 billion by 2035. 2025-2026 is a critical turning point from prototype verification to commercial pilots.
📊 Business value: efficiency improvement and cost reduction
McKinsey Estimate
Deploy Physical AI in manufacturing scenarios to:
- Overall production line efficiency increased by 20-30%
- Labor costs reduced by 40-60%
This means that even if the purchase cost of the robot is higher, the investment can be recovered in a shorter period of time through increased production efficiency and labor cost savings.
Opportunities in Taiwan: The output value of intelligent robots will exceed NT$80 billion in 2028
The Taiwan Industrial Research Institute (ITRI) predicts that by 2028, the domestic intelligent robot output value will exceed NT$80 billion.
For Taiwan’s manufacturing industry, Physical AI is:
- Automation Upgrade: Deploy Physical AI in traditional manufacturing to improve production efficiency and product quality
- Talent Transformation: Moving from repetitive tasks to robot monitoring and maintenance requires new skill sets
- Industrial chain opportunities: From parts supply to complete machine integration, there are a lot of entrepreneurial and investment opportunities
🎯 Conclusion: The next decade of Physical AI
Physical AI is moving from “long-term vision” to “deployable technology”. Three major technological breakthroughs—Robot Foundation Models, GPU-accelerated simulation, and humanoid robot hardware maturity—have jointly driven this transformation.
For enterprises, Physical AI is no longer a science fiction concept, but:
- Technology stack is ready: NVIDIA Isaac platform provides a complete development tool chain
- Business case verification: Giants such as BMW and Tesla have already conducted pilot projects in business scenarios
- Return on investment is expected: Efficiency improvement and cost reduction bring obvious business value
For developers, the barriers to physical AI development are rapidly lowering. With Robot Foundation Models and digital twins, developers can quickly iterate in virtual environments without needing to train dedicated models for each task.
The next decade of Physical AI will be a decade of moving from “laboratory” to “factory”, from “prototype” to “product”, and from “single task” to “universal robot”. And this is the era when AI truly “acts”.
