Nullmax launches physical AI base and embodied brain for robot dog

Nullmax, a physical AI company, said it has launched Nullmax Physical AI (NPI), a full-stack proprietary general physical AI technology base, and built NPI-Brain, an embodied brain providing perception, understanding, memory, decision-making and motion and manipulation control. The company said the system enables machines to move from “seeing and understanding” to “autonomous interaction with the world.”

In a recent test in its “Intelligence Transforms Everything” series, a robot dog named MAX equipped with NPI-Brain carried out long-horizon tasks in indoor, building, campus and street scenarios. It understood natural-language instructions, used memory to plan routes and moved across floors and areas without human intervention, Nullmax said. The company said the system does not require preset segmented tasks and can think autonomously with long-term memory, upgrading robots from rule execution to autonomous cognition and continuous operation.

Nullmax said its NPI Ultimate version supports voice and text multimodal interaction, allowing tasks to be issued in one sentence, and multi-turn dialogue in which the robot dog can ask follow-up questions when instructions are unclear, with interruptions, interjections and listening supported. For mobility, NPI Ultimate is driven by Nullmax’s reinforcement-learning algorithms rather than relying solely on traditional SLAM. It can identify semantic locations such as meeting rooms, reception areas and elevator lobbies, avoid obstacles dynamically and navigate across terrains, and replan and report back when routes deviate, according to the company.

Nullmax said its tokenized scene memory integrates voice, vision and status into the brain’s context, creating a closed-loop decision architecture with persistent memory and spatial awareness so the robot dog can remember environments, maintain task continuity and learn from past executions. Combined with the quadruped’s mobility, the system links semantic understanding, route planning, cross-floor movement, visual person-finding and voice interaction to complete last-mile, long-horizon tasks, it said. Nullmax said it will continue to expand the embodied brain across scenarios and adapt it to multiple robot bodies, aiming for “one brain for all, intelligence transforms everything.”
