Touchless Smart Tap Pro Kit with Arduino Uno + IR Sensors - Build a Table-Edge Avoiding Robot That Never Falls Off

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 small robot that roams freely across a bathroom counter, a study desk, or any flat surface - but the moment it reaches the edge, it stops as if it saw the void. That's exactly what you'll build with the Touchless Smart Tap Pro Kit. Using three TCRT5000 IR sensors mounted on the underside of a 2WD chassis, the Arduino Uno reads surface reflectivity continuously and halts both motors before a wheel ever leaves the table. It's a tangible, beginner-friendly way to understand how autonomous vehicles avoid cliffs, all while getting hands-on with motor drivers and sensor logic.

What You'll Build

A fully functional edge-detection robot on a two-wheel-drive chassis. You'll assemble the frame, mount the motors and castor wheel, wire the L298N motor driver and three IR modules, then upload a program that reads the sensor states. Once calibrated, the robot will cruise confidently across a tabletop and freeze at the edge - every single time. No remote control needed; the intelligence is in the sensor feedback loop you create.

What You'll Learn

• How TCRT5000 infrared sensors distinguish a surface from open air using reflected light, and how to set reliable threshold values.
• Programming the Arduino Uno to read digital/analog sensor inputs and immediately trigger motor halt logic.
• Motor driver wiring fundamentals: connecting the L298N to two DC gear motors and controlling them

  Bathroom - IR sensors on the underside stop the robot from falling off a table. Teaches floor detection logic and motor halt.
