Infinite Data Generation
for Robotic AI

Scroll

We created the world's first game engine purpose-built for robotics.

Lucky Engine spins up virtual worlds where your robot can try, fail and learn a million times. Then it steps into reality already knowing the job. No hardware to break, no lab time to book, no waiting.

01 — Lucky Engine

A new game engine built from the ground up by the Lucky Robots team

This is not Unity or Unreal. It's a game engine purpose-built for robotics. You can record at 10,000 Hz, and generate millions of accurate episodes for robotics AI training. A unique engine with accurate time and real-world physics underneath.

SIM-TO-REAL
/01 Physically accurate
Industry-standard MuJoCo contact, friction and dynamics run underneath, so a grasp learned in simulation holds on the real arm.
VULKAN
/02 Photorealistic rendering
Choose from rasterized or photorealistic path-traced rendering that runs in real-time using Vulkan. This drives camera feeds close to what the real sensors see - the difference between a vision model that works and one that doesn't.
EDITOR
/03 Full game dev experience
Build scenes procedurally or by hand, place robots and design training tasks with games-industry-standard tools and technology. You can make any environment just like you're making a game, with C# for scripting.
AI
/04 Autonomous with AI Agents
Use Claude, Codex, or other AI agents to fully control Lucky Engine, create scenes and record data. Simply tell your agent to build your project in Lucky Engine, out of the box.
DATASETS
/05 LeRobot 3.0 data output
Every motion logs camera frames, joint states and sensor streams as labeled episodes, ready for imitation and robot learning. Directly compatible with LeRobot 3.0.
ROBOTS
/06 Works with your robots
Supports any MuJoCo XML, with built-in support for robots like Unitree, Franka, Hello Robot, drones, and more.

Fly a drone through the same engine

Aerial robots run on the same MuJoCo physics and Python SDK as the arms and humanoids. Autonomous flight, captured as labeled episodes.

Articulated props Coming soon

Scenes full of objects that open

Fridges, grills and cabinets are rigged to open and close, so a policy can learn to manipulate the room, not just look at it.
