Live simulator
Line Follower Simulator: Tune a Robot in Your Browser
Draw a track, inspect live sensor readings, and tune PID control without risking hardware.
- PID
- IR sensors
- Differential drive
Simulation lab / Browser native
Robotics simulators that expose the system
Change the inputs, see the state, and understand why a robot behaves the way it does—before hardware cost or risk enters the loop.

Designed for reuse
One lab architecture. Many robot systems.
Each simulator separates deterministic engineering logic from rendering and controls. Future labs can add new models without rebuilding the surrounding learning experience.
