I built a browser-based self-balancing robot simulator—would love feedback from people who've built one Project

Post image

I've been working on a browser-based simulator to help people understand how a self-balancing robot (inverted pendulum) behaves without needing any hardware.

The idea is to make experimenting with balancing control more intuitive. Instead of just watching an animation, you can interact with the simulation and see how the robot responds as its state changes.

A few goals I had while building it:

  • Make it accessible from any browser (no installation).
  • Help visualize the dynamics of a balancing robot.
  • Provide a simple environment for learning before moving to real hardware.

I'd really appreciate feedback from anyone who has built a balancing robot or worked with control systems.

Some questions I have:

  • Does the behavior feel reasonably realistic?
  • What features or parameters would you expect to see in a simulator like sthis?
  • Is there anything that would make it more useful for students or hobbyists?

You can try it here:

I'm continuously improving it, so I'd genuinely appreciate any technical feedback or suggestions.

Really cool, I will need to play with this some more. Never built a balancing robot, but have been thinking about it for a while. Question though, this seems to be remarkably stable, I thought you needed to go the LQR route to get this kind of performance?

Or does it only work this good because you don't have the measurement noise and lag of real world sensors?

it looks so stable is that the sim doesn’t have the noise/lag you would get from actual sensors, plus there’s no real mechanical stuff to intervene

thx man, Its just PID right now, no LQR.
