9-Axis IMU LESSON 26: Understanding PID Control systems with Arduino


 

In this lesson we use our BNO055 9-axis sensor, and our pan-tilt servo mount to create a self-leveling platform based on a classic PID control system. The video takes you step by step through the theory behind a PID controller, and then demonstrates a practical example in hardware. In the video we develop the code below.

 

9-Axis IMU LESSON 24: How To Build a Self Leveling Platform with Arduino

In this lesson we develop the initial simple code for leveling the platform. We implement the simplest control system, which is to just increment or decrement the servos based on whether the actual position is greater or less than the target position. We increment/decrement by one degree, since this is the smallest allowed change in servo position. Next week we will implement a more sophisticated control system. Below is the arduino code developed in this lesson.

 

9-Axis IMU LESSON 23: Self Leveling Platform Using BNO055 and Arduino Controlled Servos

In this lesson we connect the circuit and do the mechanical build for our self leveling platform. You can see a list of the gear we are using in LESSON 22.
