My experience has taught me that educational robotics should be much more than simply building a model. A truly effective STEM lesson combines engineering, programming, testing, and improving real-world solutions.
That is why I always try to incorporate elements of mechanics and physics into my models. This may include different types of gear systems, mechanical mechanisms, or engineering structures that help students understand how technology works in the real world.
I designed this single-motor dragster specifically to help students explore different types of gear ratios:
Speed-Increasing Gear Ratios
Speed-Reducing Gear Ratios
Direct Gear Ratios
In addition, students learn about speed as a physical concept, program the robot to move, and then conduct a real engineering investigation by testing different gear combinations and comparing the results.
And of course, the most exciting part comes at the end of the lesson — dragster racing!
This is how theory becomes practice, and learning becomes an engaging process of discovery, experimentation, and innovation.
