🤯 Physical AI: Machines & Industry's Future 🚀
AI
🎧
Hitachi’s work in physical AI centers on addressing a fundamental challenge: machines’ inability to comprehend the physical world. The company, alongside partners like Daikin Industries and JR East, is developing AI systems for practical applications. In the automotive sector, Hitachi and Astemo collaborated to automate integration testing for vehicle electronic control units, achieving a 43% reduction in man-hours. Similarly, in logistics, Hitachi is modularizing robot control software using ROS. The company’s Integrated World Infrastructure Model remains in the concept verification stage, yet deployments are yielding results, including AI-driven diagnostics for air-conditioner manufacturing equipment and assistance with railway traffic management. Hitachi’s research output, notably presented in December 2025 at ASE 2025, highlights the ongoing effort to engineer safety guardrails within this complex field.
HITACHI’S PHYSICAL AI STRATEGY: A FOUNDATION OF DOMAIN KNOWLEDGE
Physical Artificial Intelligence faces a critical hurdle: the ability to operate effectively in the real world. Hitachi’s approach, centered on embedding deep domain expertise, distinguishes it from purely theoretical models. The company’s strategy prioritizes a systematic understanding of physics and industrial equipment, recognizing that this foundational knowledge is paramount for successful implementation.
SYSTEMATIC DIAGNOSTIC AI: DAINIK & JR EAST COLLABORATION
Hitachi’s partnership with Daikin Industries and JR East exemplifies the practical application of its physical AI strategy. The AI system deployed with Daikin diagnoses malfunctions in commercial air-conditioner manufacturing equipment. Trained on extensive data – including equipment maintenance records, procedure manuals, and design drawings – it identifies failing components based on operational intuition, previously reliant on experienced engineers. Similarly, the AI developed with JR East identifies the root cause of malfunctions within the Tokyo metropolitan area’s railway traffic management system, offering operators immediate assistance in formulating response plans, mitigating the impact of delays across millions of daily journeys.
ACCELERATING R&D: RETRIEVAL-AUGMENTED GENERATION
Hitachi is actively addressing a key bottleneck in industrial AI development: the lengthy process of creating and adapting control software. Through research presented at ASE 2025, the company developed a system utilizing retrieval-augmented generation to automatically produce integration test scripts for vehicle electronic control units (ECUs). This system, tested in multi-core ECU environments, reduced integration testing man-hours by 43% compared to manual execution, significantly accelerating the development pipeline.
VARIABILITY MANAGEMENT: ROBOT SOFTWARE MODULARIZATION
Furthering its focus on efficiency, Hitachi has developed variability management technology that modularizes robot control software into reusable components structured around a robot operating system (ROS). This approach allows operators to adapt robotic picking-and-placing workflows to new products or layouts without rewriting software, a critical capability for dynamic operational environments.
SAFETY AS A CORE ENGINEERING CONSTRAINT
A consistent element across all of Hitachi’s physical AI work is its emphasis on safety guardrails. Unlike a mere compliance checkbox, this is integrated as an engineering constraint within system design. Input validation screens data unsuitable for model training, output verification ensures AI actions don't endanger people or property, and real-time monitoring detects operational anomalies. This approach acknowledges the distinct operational risks associated with physical AI systems, unlike theoretical AI models operating in controlled environments.
INFRASTRUCTURE ENABLEMENT: HITACHI VANTARA & NVIDIA PARTNERSHIP
To support its physical AI initiatives, Hitachi Vantara, the group’s data and digital infrastructure arm, is collaborating with NVIDIA. They are early adopters of NVIDIA’s RTX PRO Servers, built on the RTX PRO 6000 Blackwell Server Edition GPU, optimized for agentic and physical AI workloads. Paired with Hitachi’s iQ platform, this infrastructure enables the creation of digital twins – virtual replicas of physical systems – allowing for large-scale simulations of grid fluctuations and robotic motion.
THE COSMOS PLATFORM & MODEL CONTEXT PROTOCOL (MCP)
The Integrated World Infrastructure Model (IWIM) concept, Hitachi’s overarching architecture, is designed to connect NVIDIA’s open-source Cosmos physical AI development platform with specialized Japanese-language Large Language Models (LLMs) and visual language models via the Model Context Protocol (MCP). This framework stitches together the models, simulation tools, and industrial datasets required for effective physical AI systems, representing a crucial element in the broader race for dominance in this field.
