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

Nvidia announced Nvidia Halos for Robotics in June 2026, an expansion of its Halos full-stack safety system from autonomous vehicles to robots including warehouse autonomous mobile robots, humanoid factory robots and surgical robots. Nvidia head of robotics ecosystem and edge computing Amit Goel said safety is the next bottleneck now that AI models and robot hardware are capable, and the system runs a functional system and a safety system on the same silicon, starting with the Nvidia IGX Thor computing module that has an independent processor for safety workloads. Nvidia CEO Jensen Huang said in March 2026 that the physical AI business is already driving nearly $10 billion in annual revenue.

Investors bullish on AI data centers 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. Nvidia’s Halos system launched in 2025 https://blogs.nvidia.com/blog/halos-safety-system-autonomous-vehicles/ with hardware and software tools to help developers implement guardrails in self-driving cars and other autonomous vehicles. Then the company expanded its safety architecture to more physical AI technologies by announcing Nvidia Halos for Robotics https://nvidianews.nvidia.com/news/nvidia-announces-halos-for-robotics-the-industrys-first-full-stack-safety-system-for-physical-ai in June 2026—with the goal of enabling safe deployments of autonomous mobile robots in warehouses, humanoid robots walking around inside a factory, or even surgical robots. “Now the AI models are getting capable, the robot hardware is getting capable, and a thing we thought is going to be the next bottleneck is safety,” Amit Goel https://www.linkedin.com/in/amit-goel-759146a/ , head of robotics ecosystem and edge computing at Nvidia, told Ars. “So that’s why we launched our Halos for Robotics to unlock the capability of these systems.” The expanded safety offering for robotics comes as Nvidia CEO Jensen Huang described the physical AI business as already driving nearly $10 billion in annual revenue for the company during an appearance on the All-In Podcast https://www.youtube.com/watch?v=gwW8GKwHB3I&t=292s in March 2026. Huang previously began highlighting physical AI as Nvidia’s second-most important growth category https://www.cnbc.com/2025/06/25/nvidia-shareholder-meeting-2025-robots.html in 2025. Expanding safety from AVs to robots So what does Nvidia’s full-stack safety system involve? It starts with hardware, such as the Nvidia IGX Thor computing module https://www.nvidia.com/en-us/edge-computing/products/igx/? gl=1 v2qmyc gcl au MTI4NjQ3NTk1NC4xNzg3MDgxMjE0Li0uLS4xNzg3MDgxMjEzLjIyNDgzMjMyMy4xNzkxMzk2NDA0LjE3OTE0MDkwMzc. for robotics and industrial applications that has an independent processor dedicated to safety-related workloads. “In the context of physical AI, you need to have your functional system and your safety system all running on the same silicon,” Goel said.
