As part of the Summer Camp at Anne Hill Bilingual Primary School, this week’s Robotics lesson offers students a hands-on experience: build a mini fan and learn about gear ratios through gears and belts.
In today’s session, students investigate the basic parts of a fan: motor, shaft, gears or pulleys with a belt. They see that the gear ratio determines how fast or slow the fan spins and how much force it produces. For example, a small gear on the motor driving a larger gear on the fan gives more torque but lower speed; the reverse gives higher speed but less torque.
Through this activity, students will:
- Understand and apply real-world principles of motor plus transmission
- Experiment with gear ratio notice differences in speed and force
- Improve observation and analysis when assembling and adjusting the drive system
- Develop teamwork share findings and discuss improvements
- Spark curiosity from a simple mini fan to more advanced Robotics projects
