Robotics research should not start with a week of setup.
The engine, the robots and the python runtime ship with the page. Your setup time is the time it takes to open a tab.
Everything you need. Nothing to set up.
Bring your own robot
Upload yours, or start from one that is ready to go.
Real physics
Things fall, collide and settle the way they should.
python control
Move the robot, read where it is, and try again.
Inverse kinematics
Point at where you want the hand. It works out the rest.
Save your work
Every scene and script opens right where you left it.
Nothing to install
Open a tab. It is already running.
Things you're probably wondering.
Do I need to install anything?
Nope! Everything runs in your browser. No CUDA install, no ROS, no Docker image.
Is this real MuJoCo?
Indeed, the real thing. Same contacts, same friction, same joint limits. No physics shortcuts.
Which robots can I use?
Franka Panda and Hello Robot Stretch 3 are ready to go, and they stick around after the first load. Or bring your own, we will not judge your mesh count.
What can I write in python?
Motion, inverse kinematics, sensor reads, and questions about the model. Tell the arm where to go and it figures out the angles itself.
Can I describe a scene in plain English yet?
Not quite yet. That one is still in the oven. For now you build scenes as MJCF and drive them from python.
Built by roboticists, for roboticists.
The problem
Getting a robot simulation running used to take days of setup, and then nobody else could reproduce it, because the whole thing lived on one machine.
Our approach
We put it all in a browser tab. Open a link and you are already running: same scene, same physics, same result, on any machine.
