Learn Coding by EV3 LEGO Robot

“Learn Coding by EV3 LEGO Robot”  is a fantastic hands-on learning experience for kids! We used Project-Based Learning to teach robotics, design, and electronics in an engaging way. 

Coding Meets Creativity: Designing and Programming Painting Robots

In this hands-on STEM workshop, students begin their journey with 3D design, creating the body and mechanical components of their robot using Tinkercad. This stage encourages creativity and spatial thinking as children plan the structure that will bring their robot to life.

Next, students move on to coding, where they program the robot’s movements and behaviors using a microcontroller. This step introduces foundational coding concepts, allowing learners to see how their instructions directly control the robot in real time, blending logic with creativity.

Finally, the project is concluded by electronics wiring and mechanical assembly. Students connect motors and sensors to the microcontroller, integrating all components into a fully functional robot. By combining mechanical making, wiring, and programming, kids gain a comprehensive understanding of how technology, engineering, and coding work together in a fun, project-based learning environment.
