Intro to the Tamiya 75020 Line Follower Snail

The Tamiya 75020 Line Tracing Snail is a compact build that showcases sensor-controlled motion for makers and students. The transparent high-impact polystyrene body reveals internal gears and motor placement so builders can study how the mechanism works. Powered by two Type 130 motors and using an infrared LED sensor, the model follows a dark line on a lighter background to illustrate basic automation. The rubber tyres deliver reliable grip on smooth indoor surfaces, making it an ideal learning project for clubs and classrooms.

  • Body: High-impact polystyrene (HIPS) plastic
  • Motors: Twin Type 130 motors
  • Sensor: Infrared LED line sensor

What surface works best for line tracing?

Flat, non-reflective surfaces with a clear dark line on a light background give the most reliable results. Avoid glossy floors that can confuse the infrared sensor.

Is assembly suitable for school-age learners?

Yes. The kit is aimed at introducing concepts of mechanics and electronics, so with supervision it works well for secondary school tech classes and maker groups.

What maintenance does the kit require?

Keep the sensor lens clean and check gear mesh for smooth operation. Replace batteries before long sessions and inspect tyres for wear to maintain consistent tracking.
