About One Robot
Summary
One Robot builds world model-based simulation environments for robotics teams training and evaluating manipulation policies. The environments replicate both the visual appearance and physical behavior of real scenes, covering contact-rich tasks, deformable objects like textiles, and precise assembly. This lets teams run experiments, surface edge cases, and generate targeted synthetic training data without consuming physical robot time or setting up real-world trials.
Go-to-market
Robotics teams building action models for manipulators are the target customers, reached directly through outreach to founders and researchers working on hard manipulation tasks.
From the Y Combinator listing
World models for robot evals and training.
One Robot builds simulation environments that are realistic to see and realistic to interact with, so robotics teams can train and evaluate robot policies without being bottlenecked by robot time. Today, improving a VLA often means more real-world hours: setting up the scene, running trials, resetting, and repeating. This loop is slow, expensive, and hard to scale. For example, material handling and manufacturing assembly tasks, models need far more training and evaluation data than teams can collect in the real world. We use task-specific data to build world model-based simulation environments for hard manipulation tasks (for example, textiles and box folding). These environments help teams run more training and evals, find failure modes faster, and accelerate iteration on action policies with less dependence on real-world data collection and robot availability.
