This could be investigated further later. This could be investigated further later.
We were very successful with implementing a Party Finder Robot using a PD controller and the DifferentialPilot class in the leJOS API. We were very successful with implementing a Party Finder Robot using two sound sensors, a PD controller and the DifferentialPilot class in the leJOS API.
The calibration and choice of gain parameters could probably be optimized to give an even better performance. The calibration and choice of gain parameters could probably be optimized to give an even better performance.
