Spike Prime - Color Sorter - Teacher Resources
From RoboWiki
Complexity of the task: Medium, students now they will learn to use a camera and the OpenCV library to detect and sort objects based on their color.
Lesson Plan
1. Prepare
- Review the student material and ensure all necessary resources are ready.
2. Engage (10 Min.)
- Introduce the lesson by demonstrating a prototype of a colored object sorter robot. Explain the project goal: to develop a robot that uses the OpenCV library to identify and sort objects by color.
- Discuss the importance of color sorting technology in various industries, such as recycling and manufacturing.
- Spark curiosity with questions like "What challenges might arise in developing an autonomous color sorting robot?" and "How can computer vision help solve these challenges?"
3. Explore (30 Min.)
- Guide students through setting up their development environment, including installing OpenCV and configuring their camera.
- Demonstrate key OpenCV functions, such as capturing images and basic color detection, to help students understand its capabilities.
- Provide sample code snippets and tasks for students to experiment with color detection and sorting algorithms, encouraging hands-on learning.
4. Explain (10 Min.)
- Explain how OpenCV processes visual data to detect colors in images or video streams.
- Discuss key color detection techniques, such as color space conversion and thresholding, and show how these are implemented in OpenCV.
5. Elaborate (30 Min.)
- Encourage students to enhance their projects by brainstorming and implementing additional features for the colored object sorter robot.
- Challenge them to consider improvements such as enhancing color detection accuracy, integrating multi-object detection, or optimizing the sorting mechanism.
- Provide support and resources to help students explore new concepts and extend their understanding.
6. Evaluate
- Assess students' understanding and practical skills by observing their progress in developing the colored object sorter robot.
- Offer constructive feedback, highlighting strengths and areas for improvement in their implementations.
- Promote self-reflection and peer feedback to encourage ongoing learning and improvement.
