Spike Prime - Line Following Car - Jakub Vojtek

Back to: List of projects of Spike up Prime Interest in Science and Technology with Raspberry Pi Build Hat

About the project

This project is a line-following robot, designed to autonomously navigate along a pre-defined path. The robot uses camera to detect and follow a line, typically a contrasting strip of color on the ground. By continuously adjusting its steering to stay on the line, the robot can move accurately along complex routes.

Build a robot

• Be careful with the wires while building so they don't get stuck in wheels.

Building instructions:

• Line Follower (pdf)

• Line Follower (stud.io)

Get the robot ready

• Pick the desired color range in HSV (Hue, Saturation, Value) from color_picker script.
• Edit wheels speed to work for your project (faster for smaller turn angles, slower for bigger turn angles).
• Place your robot on the start of the line.

Raspberry Python Code:

• Line Following Car - Code
• Color Picker - Code

Ideas for improvement

• Make the robot speed up if the line is straight and slow down before the turn.
• Try to make the robot make as sharp turn as you can.

Evaluate your performance

• Think about how you approached the problem and about how else could it be solved.
• Evaluate yourself on how you adapted when something didn't work as you hoped it would.
