Intuition Robotics' core bet is that the transfer from simulated to physical worlds is unlocked by a shared action interface. Since many real-world robots like drones and arms are already operated with game controllers, an agent trained in diverse gaming environments only needs to adapt to a new visual world, not an entirely new action space.

A Rice PhD showed that training a vision model on a game like Snake, while prompting it to see the game as a math problem (a Cartesian grid), improved its math abilities more than training on math data directly. This highlights how abstract, game-based training can foster more generalizable reasoning.
Instead of developing proprietary systems, the military adopts video game controllers because gaming companies have already invested billions perfecting an intuitive, easy-to-learn interface. This strategy leverages decades of private-sector R&D, providing troops with a familiar, optimized tool for complex, high-stakes operations.
GI is not trying to solve robotics in general. Their strategy is to focus on robots whose actions can be mapped to a game controller. This constraint dramatically simplifies the problem, allowing their foundation models trained on gaming data to be directly applicable, shifting the burden for robotics companies from expensive pre-training to more manageable fine-tuning.
Large language models are insufficient for tasks requiring real-world interaction and spatial understanding, like robotics or disaster response. World models provide this missing piece by generating interactive, reason-able 3D environments. They represent a foundational shift from language-based AI to a more holistic, spatially intelligent AI.
Beyond supervised fine-tuning (SFT) and human feedback (RLHF), reinforcement learning (RL) in simulated environments is the next evolution. These "playgrounds" teach models to handle messy, multi-step, real-world tasks where current models often fail catastrophically.
GI's founder argues game footage is a superior data source for spatial reasoning compared to real-world videos. Gaming directly links visual perception to hand-eye motor control ("simulating optical dynamics with your hand"), avoiding the information loss inherent in interpreting passive video, which requires solving for pose estimation and inverse dynamics.
Physical Intelligence demonstrated an emergent capability where its robotics model, after reaching a certain performance threshold, significantly improved by training on egocentric human video. This solves a major bottleneck by leveraging vast, existing video datasets instead of expensive, limited teleoperated data.
To protect user privacy, GI's system translates raw keyboard inputs (e.g., 'W' key) into their corresponding in-game actions (e.g., 'move forward'). This privacy-by-design approach has a key ML benefit: it removes noisy, user-specific key bindings and provides a standardized, canonical action space for training more generalizable agents.
Instead of simulating photorealistic worlds, robotics firm Flexion trains its models on simplified, abstract representations. For example, it uses perception models like Segment Anything to 'paint' a door red and its handle green. By training on this simplified abstraction, the robot learns the core task (opening doors) in a way that generalizes across all real-world doors, bypassing the need for perfect simulation.
Unlike older robots requiring precise maps and trajectory calculations, new robots use internet-scale common sense and learn motion by mimicking humans or simulations. This combination has “wiped the slate clean” for what is possible in the field.
