Nvidia's big bet on physical AI aims for safer robotaxis, humanoid robots

What happened

Nvidia's Halos system launched in 2025 with hardware and software tools to help developers implement guardrails in self-driving cars and other autonomous vehicles. Full-stack safety solution for physical AI is being used by robotics companies. NVIDIA is a semiconductor company based in Santa Clara, and its products and services include software.

Investors bullish on AI data centers (a building full of computers that runs online services) may be fueling Nvidia’s multi-trillion-dollar market capitalization, but the AI chipmaker has also bet billions of dollars on physical AI technologies such as robotics and self-driving cars. Part of that gambit has involved Nvidia developing a full-stack safety system that companies can build upon to reduce the risk of their machines harming nearby people.
