That sounds like a fantastic hands-on learning experience for kids! You’re using Project-Based Learning (PBL) to teach robotics, design, and electronics in an engaging way. Here’s a possible structure for your Painting Robot Project:

Project Steps:

Project Steps:

1. Concept & Planning
   • Discuss what a painting robot is and how it works.
   • Brainstorm design ideas (types of movement, painting styles).
   • Sketch initial robot concepts.
2. 3D Design (Tinkercad)
   • Design the body and mechanical parts of the robot.
   • Ensure space for motors, electronics, and paint mechanisms.
3. Electronics & Wiring (Circuit Design)
   • Use Tinkercad Circuits or real components for prototyping.
   • Select EV3 as microcontroller.
   • Choose sensors, 2 DC motors as a actuators for movement and painting.
   • Wire and test electronic components.
4. Programming
   • Write code to control robot movement and painting patterns.
   • Use block-based coding (for beginners) or Python (for advanced students).
   • Test basic commands and refine.
5. Assembly & Integration
   • Build the final robot by combining the 3D-printed frame and electronics.
   • Attach a paintbrush or marker mechanism.
   • Ensure all parts fit and function together.
6. Testing & Improvement
   • Adjust movement, brush pressure, or paint delivery.
   • Encourage kids to modify and personalize their robot.
7. Presentation & Reflection
   • Demonstrate the robot’s painting skills.
   • Discuss what worked well and what could be improved.
   • Document the learning process.
