Tamiya 75027 - Line Tracing Snail II  [75027]

Overview

The Tamiya 75027 Line Tracing Snail II is an engaging STEM educational model kit designed to introduce enthusiasts to basic robotics and circuitry. This kit constructs a charming snail model capable of following a black line on white paper, providing an interactive and educational experience suitable for hobbyists and young learners alike.

Design and Functionality

Equipped with a smoke-colored ABS resin chassis and body, the Line Tracing Snail II features two motors and pre-wired components, including sensors and a circuit board. The model uses an infrared LED and phototransistor to detect lines, allowing it to navigate autonomously. The LED lights up green when it detects a black line, adding a visual cue to its operation.

Technical Features

The kit includes a speed switch for adjusting performance and a sensor adjustment dial to fine-tune its responsiveness. As the snail encounters a black line, its right motor activates, guiding it forward and left. When off the line, the left motor engages, steering it right. This alternating process enables the snail to follow the line continuously.
