Touchless Smart Tap Robot That Follows a Line to the Water Source with Arduino Uno

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a little robot that you can place in your bathroom—it follows a black tape line right up to the tap, ready to assist without anyone touching anything. With this kit, you build exactly that: a two-wheeled bot that reads the floor using two IR sensors and steers itself along a path you design. It’s a playful first step into robotics, grounded in real sensor logic and motor control.

What You'll Build

You will assemble a 2WD line-follower on a transparent acrylic chassis, mount two TCRT5000 IR modules underneath, and wire them to an Arduino Uno with an L298N motor driver. Once calibrated, the robot hugs a black line on a light floor, adjusting motor speeds to stay on track. The result is a smart tap assistant that autonomously navigates to a water point—perfect for demonstrating autonomous guidance in a simple, visible way.

What You'll Learn

• Calibrating IR sensor thresholds to distinguish black tape from light surfaces
• Controlling TT gear motors with an L298N driver using PWM signals
• Writing Arduino code that reads two sensors and makes real-time steering decisions
• Troubleshooting a robot: tracing signals with jumpers and verifying connections

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Young makers in ATL Tinkering Labs and CBSE classrooms will find this kit an exciting entry into robotics. It’s also a hit with home hobbyists aged 5-15 who want to see sensor data translated into motion immediately. Even first-year engineering students at institutions like VIT, NIT, or BITS use it to refresh motor driver basics before advanced projects.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
