5. Customizing the Dashboard Open Project Sending data from robot Smart Dashboard VI s Named (case sensitive) values

6. SENSORS

7. Sensors - Encoder

8. Sensors - Encoder Places to use encoders: When trying to measure rotational speed Trying to measure rotational distances possibly greater than 8 rotations. Don t care about starting position

9. Sensors - Encoder Places to use encoders: When trying to measure rotation speed Trying to measure rotational distances possibly greater than 8 rotations. Don t care about starting position Examples: Drive train Fly Wheel/wheeled shooter

10. Sensors - Encoder Reading

11. Sensors - Encoder Control

12. Sensors - Potentiometer

13. Sensors - Potentiometer Places to use potentiometers: Trying to measure rotational distances less than 8 rotations. Care about starting position or absolute positions Examples: Arm angles Elevator positions

14. Sensors - Potentiometer Control

15. Sensors - Potentiometer Note: Easy way to make potentiometer relative to a known point: https://www.frclabviewtutorials.com/tutorials/sensors/roborio/pot entiometer/

16. Sensors - Gyro

17. Sensors - Gyro Places to use a Gyro: When trying to drive perfectly straight When trying to turn to specific angles (especially in auto)

18. Sensors - Gyro Control

19. PID Proportional

20. PID Proportional Constant multiplied by error (offset) The larger this is, the faster the robot approaches the setpoint (smaller rise time)

21. PID Proportional Constant multiplied by error (offset) The larger this is, the faster the robot approaches the setpoint (smaller rise time) Integral Constant multiplied by integral of all previous error values The larger this is, the less overshoot and settling time (less bounce)

22. PID Proportional Constant multiplied by error (offset) The larger this is, the faster the robot approaches the setpoint (smaller rise time) Integral Constant multiplied by integral of all previous error values The larger this is, the less overshoot and settling time (less bounce) Differential Used to eliminate steady state error (reducing offset after movement)

23. PID Proportional Constant multiplied by error (offset) The larger this is, the faster the robot approaches the setpoint (smaller rise time) Integral Constant multiplied by integral of all previous error values The larger this is, the less overshoot and settling time (less bounce) Differential Used to eliminate steady state error (reducing offset after movement)

24. PID Tuning

25. PID Tuning Several methods available Ziegler Nichols* Tyreus Luyben Cohen Coon str m-H gglund Manual Tuning*

26. PID Tuning Manuel Raise CPUntil robot oscillates about setpoint Raise CDUntil Robot stops bouncing Raise CI(and change the setpoint) until robot turns and hits the target point Ziegler-Nichols Raise CPUntil robot oscillates (Value of CPbecomes Ku) Measure the period of this oscillation (Time to complete 1 cycle becomes TU)
