RUST ROBOTICS / IN YOUR BROWSER

See the idea.
Move the robot.

Draw a route. Find your position. Tune a controller. Explore robotics through experiments you can change, replay, and share.

01 / PATH PLANNINGPLAYGROUND CAPTURE

Find a way through.

Replay A* and Dijkstra's search, then compare all four planners on your map.

Try this: replay A* and Dijkstra on the same map. Pause and advance one cell.

No install. No account. Real algorithms, running here.

PICK A QUESTION. TRY A CHANGE.

11 interactive demos

Open a scene, change one thing, and watch what happens. Use Share in the playground to keep the configuration.

New in Control: which way should the robot turn? Inspect actual velocity samples and discover why a local arc wins or collides.

Explore in SLAM: what should the robot discover next? Uncover hidden rooms and inspect the actual frontier choices.

Build a map in SLAM: what makes a wall disappear? Replay actual LiDAR evidence and compare farther returns with missing observations.

New in SLAM: match a LiDAR scan point by point. Drag its initial pose and discover why a tiny residual can still give the wrong location.

Also in Control: inspect a safety filter's decision. Move an obstacle and compare the velocity correction with the unfiltered path.

Also in Planning: wait or take the detour? Change a gate's closing time and compare two routes on one clock.

01Change one thing
Draw a wall, add sensor noise, or lower a controller's turn response.
02Watch the difference
Follow the route, estimate, or motion. Compare the results in the scene.
03Keep exploring
Share the configuration, try another method, or open the Rust implementation below.

ALSO IN THE PLAYGROUND / FLIGHT

Fly five gates, race an autonomous ghost, build a circuit, and photograph your flight.

Your first flight

Move forward and climb
Hold W + E, or hold the forward and UP buttons with two fingers. Release to brake.
Aim for the gold gate
Pass through each numbered opening in order. A / D steer; Q descends. The purple drone is the autopilot.
Replay, photograph, share
Space pauses. R retries. P opens Photo mode. Use Share to send the same flight to a friend.

The flight waits for your first input. Open How to play or press H whenever you need a reminder.
