## Digital Twins Advance Safety Validation in Humanoid Robots

Infineon Technologies has expanded its collaboration with NVIDIA, developing digital twin-based system architectures that integrate semiconductors, simulation platforms, and cybersecurity elements. This work aims to achieve the system integration necessary for the safe and effective operation of humanoid robots in industrial and service sectors.

Humanoid robots require tightly integrated sensing, processing, actuation, and safety systems to perceive their environment, process data, and move in real-time. Infineon's semiconductor technologies include motor control systems, microcontrollers, power electronics, and hardware-based security components, while NVIDIA provides AI processing platforms and robotic software frameworks.

### Simulation-Supported Development with Digital Twins

Digital twins representing Infineon's smart actuators and certain sensors are integrated into NVIDIA Isaac Sim and Isaac Lab simulation environments, where tests are conducted for motion control, sensing, and interaction scenarios. This approach allows for the identification of software and hardware integration issues in a virtual environment before physical production, thereby accelerating engineering processes.

Simulations help test robot behavior under realistic operating conditions and ensure compliance with automated production environments and digital supply chain processes.

### Technical Specifications

### Functional Safety and Certification

The collaboration includes hardware and software integrations that meet functional safety requirements for tiered autonomous systems in robotic applications, leveraging the NVIDIA Halos security framework. Infineon provides semiconductor platforms and cybersecurity mechanisms that support functional safety in the sensing, control, and actuation layers.

### Infineon's Robotic Semiconductors

Infineon's portfolio includes sensors, microcontrollers, actuators, Ethernet-based connectivity components, memory products, and battery management systems. The semiconductor technologies are based on silicon (Si), silicon carbide (SiC), and gallium nitride (GaN).

The average semiconductor content cost for a humanoid robot is approximately $500, covering components for physical sensing, control, actuation, and connectivity functions.

This joint effort aims to develop hardware platforms that will support the transition from the prototyping phase to industrial applications in the field of robotics.
