# Moving Atoms > Moving Atoms builds RobotGym, simulation infrastructure for physical AI. Build a digital twin of your workspace from photographs, run your robot in it with real physics and keep the evidence of every trial. Moving Atoms builds RobotGym, simulation infrastructure for physical AI: teams rebuild a workspace as a digital twin from photographs, video, documents and CAD, run their robot against it with real physics and declared budgets, and download the evidence of every trial. Atom, the simulation agent, builds twins and designs tasks in conversation. The current evaluation harness supports GPT-6 Astra, Claude Fable 5 and Claude Fable 5.1 as policies on a simulated Franka Panda. Results on this site are single recorded trials, never success rates. Physics pauses while a policy thinks, so wall-clock figures are not real-time figures. This is a marketing site. The product lives at https://robotgym.io with documentation at https://robotgym.io/docs and pricing at https://robotgym.io/pricing. Content Signals: search=yes, ai-input=yes, ai-train=no. ## Product - [Home](https://movingatoms.ai/): what RobotGym does, how a run works, two recorded trials. ## Solutions - [Industrial automation](https://movingatoms.ai/solutions/industrial): Validate a cell from photographs, drawings and CAD before it is commissioned. - [Manipulation](https://movingatoms.ai/solutions/manipulation): Test grasps and placements in the room you photographed, with real contact physics. - [Research and benchmarks](https://movingatoms.ai/solutions/research): Frozen scenes, seeds and budgets, with evidence archives reviewers can open. - [Embodied AI evaluation](https://movingatoms.ai/solutions/model-evaluation): Put frontier models in a body and hold everything else fixed. ## Platform - [Environments](https://movingatoms.ai/platform/environments): Digital twins from photographs, documents and 3D assets. - [Evaluation](https://movingatoms.ai/platform/evaluation): Declared budgets, independent verdicts, every attempt kept. - [Atom](https://movingatoms.ai/platform/atom): The agent that builds the twin, designs the task and shows its working. - [Data](https://movingatoms.ai/platform/data): Every run is a downloadable, replayable record. - [RobotGym documentation](https://robotgym.io/docs): the authoritative product reference. - [Pricing](https://robotgym.io/pricing): Research $100 a month, Lab $300 a month, Enterprise by arrangement.

Watch the recorded run, then make the environment your own on RobotGym. Live environment: https://robotgym.io/environments/returns-conveyor - [Precision microscopy](https://movingatoms.ai/demos/precision-microscopy): A robot exchanges a chambered specimen on an inverted microscope: remove the retainer, return the finished slide, orient the next sample and restore the fixture. Live environment: https://robotgym.io/examples/precision-microscopy - [PCBA fixture loading](https://movingatoms.ai/demos/pcba-fixture-loading): Load a circuit board onto precision locating pins in an editable electronics laboratory, then retrieve it vertically and place it in the output nest. Explore the cell, watch the run, then make the environment your own. Live environment: https://robotgym.io/examples/pcba-fixture-loading ## Company - [Customers](https://movingatoms.ai/customers): who the platform is for, the design-partner program, public recorded runs. - [About](https://movingatoms.ai/about): the founders and how we work. - [Press kit](https://movingatoms.ai/press): boilerplate, facts, bios, logo files and product images. - [Careers](https://movingatoms.ai/careers): open roles in the United Kingdom. - [Contact](https://movingatoms.ai/contact): founder@movingatoms.ai reaches both founders. ## Blog - [Declared, not assumed](https://movingatoms.ai/blog/declared-not-assumed): The five contracts, the recording rule, the primitive layer and the admission check we build RobotGym against, and the anti-patterns we refuse. - [One photograph, one mug, one trial](https://movingatoms.ai/blog/one-photograph): Atom rebuilt a kitchen from one public photograph and an agent lifted the mug 8.2 cm in a single recorded trial, with every caveat written down. - [Both clocks, every run](https://movingatoms.ai/blog/both-clocks): Physics pauses while the model thinks, so every RobotGym run records simulated and wall time separately and never reports one as the other. - [Two doors into one controller](https://movingatoms.ai/blog/two-doors): A language model can drive an arm one primitive per call or by writing a short program, and we ship both doors over one controller. - [What a policy sees](https://movingatoms.ai/blog/what-a-policy-sees): Three RGB cameras, the measured gripper pose and camera calibration are what reaches a model in RobotGym, and we record exactly what it saw. - [Why we build environments](https://movingatoms.ai/blog/hello-world): RobotGym in plain facts, why we think the physical world is the slow part of robot development, and what we will write about here. ## Open roles - [Founding engineer, simulation and agents](https://movingatoms.ai/careers/founding-engineer): Full time, United Kingdom. Build the simulator, the harness and the evidence format behind RobotGym, working directly with the two founders. ## Public evidence - https://movingatoms.ai/showcase/kitchen/episode-evidence-v3.json: the recorded kitchen run (329 steps, 10 model calls, 8.2 cm lift). - https://movingatoms.ai/showcase/kitchen/atom-program.py: the ten programs the model wrote in that run. - https://movingatoms.ai/showcase/pi/episode-evidence-v2.json: the earlier-release π0.5 demonstration. ## Contact - Sales, design partnerships, press and roles: founder@movingatoms.ai.
