Robotics you can drag around
Interactive tools for kinematics, control, and motion planning. Each one is a thing you can pull on until the math stops being abstract. Source is on GitHub.
- How to Tune a PID Controller by HandLearn what each PID gain does with an interactive simulation. Tune a controller yourself and see how P, I, and D change the response.
- Inverse kinematics, two waysEvery reachable point has two arm configurations. Which one you pick is a real engineering decision, and the tool shows you why.
