One of my favorite things about Panda is how easy it is to put together a simple, visual simulation to test an idea. For the FIRST Robotics competition this year, I programmed a very simple robot arm simulator (pendulum physics and a PID controller) that teachers can use to demonstrate basic principles of feedback control. It took about three hours total to put together
If you’d like to try it, the simulator is located at http://fixermark.googlepages.com/ArmSimulator.zip. Let me know what you think!
