Advance Line following the PID Algorithm

In the advanced line-following extension, users can achieve rapid and efficient line tracking through two distinct approaches with Quarky: one employing Adaptive Feedback with PID (Proportional-Integral-Derivative) for precise and responsive navigation, and the other without adaptive feedback and PID, relying on a straightforward method. These dual strategies cater to users with varying preferences, allowing for a flexible and dynamic experience in optimizing line-following performance based on individual needs and scenarios.

But what is a PID Algorithm? A PID line follower is like a smart robot that can follow a line on the ground. Imagine drawing a black line on a white surface, and you want a robot to stay on it as it moves. That’s where PID (Proportional, Integral, Derivative) control comes in. Continue reading to learn about PID parameters and functions.

Set PID Line Following Parameter

1. For Block Coding Select set PID Kp Block and set the parameters

2. For Python Programming use the following function:

Python function: setPIDconstantparameter(0.8,0.01,0.2)

PID control of the line follower consists of proportional, integral, and derivative functions to improve the robot’s movement. 

Proportional: This part helps the robot make small adjustments based on how far it is from the line. If it’s too far to the right, it steers left, and if it’s too far to the left, it steers right.

Integral: The integral part looks at how long the robot has been off the line. If it has been off for a while, the integral part helps to make a bigger correction to bring it back on track.

Derivative: The derivative part predicts future errors by looking at the rate at which the robot moves away from the line. This helps the robot make smooth adjustments and avoid overshooting the line.

So, the PID controller combines these three components to continuously adjust the robot’s movements, keeping it as close to the line as possible. It’s like a robot always learning and fine-tuning its path to stay on track.

Think of it as a smart system that balances and corrects itself as it moves, ensuring it follows the line accurately. PID line followers are commonly used in robotics competitions and educational settings to teach about control systems and automation.

If you initialize a three-IR line following, use kp >= 7 for a better result

Set PID Speed Line Following Parameter

1. For Block Coding select set PID speed parameter base, and set the following parameter

2. For Python programming, use the following function:

Python function: setPIDspeedparameter(40,0,80)

Base speed is the speed of the line following.

Min. Speed is the minimum motor speed when the robot is turning.

Max. Speed is the maximum motor speed when the robot turns, and the black line is detected.

Do line following with PID

1. For Block Coding select do line following with PID block.

2. For Python Programming use the following function:

Python function:- dolinefollowingwithPID()

The function initiates the line following using the PID algorithm and stops the robot when the checkpoint is detected. You must set the IR threshold to stop the robot at the checkpoint. Adjust the PID parameters for optimal line-following performance. You must set the PID speed and constant parameters to start the line following.

Notes:

• Set the correct threshold for the IR sensor for better results.
• If your robot is not stopping at the checkpoint or not following the line, consider making modifications to align the external IR sensor parallel to the caster wheel.
• Experiment with the PID speed parameter and overall speed value to achieve better line following.
• Please ensure the position of your external IR sensor is not placed too high from the ground and not too low; you need to calibrate on the arena.

Advanced Sensors for Precise Calibration

Users can seamlessly integrate advanced sensors like the APDS 9960 color sensor, MPU6050 gyroscope, and accelerometer (motion sensor) in the advanced sensor extension with Quarky. This combination empowers users to harness the full potential of color and light detection and also measure the proximity and motion sensing capabilities in their projects, allowing users to create dynamic and responsive projects that leverage the precise color identification of the APDS 9960 and the motion-tracking capabilities of the MPU6050 gyroscope and accelerometer.

Notes:

• A gyroscope is essential for determining an object’s rotation rate or change in orientation. The MPU6050 includes a three-axis gyroscope that measures angular velocity along the X, Y, and Z axes.
• An accelerometer can detect changes in velocity or inclination and provide information about the static acceleration due to gravity. The integrated three-axis accelerometer in PictoBlox measures acceleration along the X, Y, and Z axes.

Updates in Quarky Settings and Troubleshooting

With the introduction of new extensions, we have updated Quarky settings for the smooth transfer of information.  Here are a few updates that you can go through to troubleshoot your robot:

Output and Input (GPIO) Pins Testing

• If your digital pin output commands are not working properly, you can test the hardware pins using the blink option. On clicking the ON button, the corresponding pin will go high and low periodically, and you can test with an LED or multimeter if the hardware pin state is changing or not.
• Similarly, to test some sensors’ input values to the hardware pins, you can stream the values read by the Quarky pins continuously by clicking the Get button. You can validate the proper functioning of your Quarky input pins and calculate the threshold for your analog sensors.

Ultrasonic Sensor Test

You can validate the proper functioning of your Ultrasonic sensor by connecting the echo and trig pins of your ultrasonic sensor to the D1 and D2 pins, respectively. On pressing the Get button, you will continuously get the distance measured by the ultrasonic sensor if the sensor works correctly.

If you don’t get the distance, please check if your operating sensor is a 3.3V compatible sensor, as Quarky does not support 5V logic-level sensors.

Distinguishing 3.3V and 5V Ultrasonic sensors

Check for the part number on the sensor (depicted by the Green box in the image below). Search for the text HC-SR04+, which means it is 3.3V compliant. If the part number is HC-SR04, it is a 5V version and won’t work with Quarky.

You can also distinguish the 3.3V and 5V sensors by looking at the backside of your sensor and differentiating the presence of the C7 capacitor (depicted by the Red highlight box in the image below):

RGB Test

If you want to test the proper functioning of the RGB LEDs on your Quarky, press the run button, and an LED test sequence will run on your board, which you can observe to validate the RGB LEDs. The test sequence would be as follows:

• The complete grid would follow the pattern of colors: Red, Green, Blue, and then White.
• The white color pattern will go from low brightness to high and then from high to low.
• Finally, the rainbow pattern will run on the board.

This above sequence will help you identify any faulty LED on the board.
