Summary
The PID controller is a great way to build robot behavior that adjusts to sensor input. In this chapter, you learned what a PID controller and its components are, including where a low-pass filter makes it behave better.
The PID controller allows for dynamic responses but requires a lot of tuning to get it right. You’ve seen how to add a wireless control method, which is essential for tuning a PID. You’ve also observed the graphs of PID systems, understanding how they relate to their operations and tuning.
In the next chapter, we will be taking our PID controller and using it with encoders to drive in straight lines.
