Smart Trash Can Auto-Open Kit with Arduino Uno + Ultrasonic
Smart Trash Can Auto-Open Kit with Arduino Uno + Ultrasonic: Build a Touchless Bin Robot That Solves Mazes
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a simple 2WD chassis into a smart trash can that navigates autonomously using left-hand wall following. With two HC‑SR04 ultrasonic sensors, this Arduino-powered robot can find its way through a simple maze while a front-mounted bin opens automatically when it detects a hand wave. Ideal for young makers, school science projects, and any robotics enthusiast eager to master sensor-based navigation.
What You'll Build
You’ll assemble a mobile robot equipped with a small trash bin. The robot follows the left wall continuously, using two ultrasonic sensors—one pointing left to maintain wall distance and the other pointing forward to detect corners and obstacles. When a person approaches from the front, the second sensor triggers a simple mechanism that lifts the bin lid, turning your robot into a touchless waste collector. The final build moves smoothly around rooms, corridors, or maze paths, demonstrating autonomous wall‑following behaviour.
What You'll Learn
- How ultrasonic sensors measure distance and feed data to an Arduino
- How to program a left-hand wall-following algorithm for maze navigation
- How to control DC motors through an L298N driver for precise movement
- How to integrate sensor feedback with actuator logic to create a responsive robot
