Maze Solving Robot Kit with Arduino Uno + Ultrasonic
Build an Autonomous Maze-Solving Robot with Arduino Uno and Ultrasonic Sensors
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 robot that drives itself through a maze, hugging the left wall and finding its way out—without a remote control or human intervention. This kit puts you behind the wheel of that creation, using an Arduino Uno brain and two HC-SR04 ultrasonic sensors as its eyes. In one afternoon, you’ll assemble, wire, and code a 2-wheel-drive robot that implements the classic left-hand wall following algorithm. Every turn becomes a lesson in sensor integration, motor control, and logical problem-solving.
What You'll Build
A self-contained, battery-powered robot that navigates simple mazes autonomously. The two forward-facing ultrasonic sensors constantly measure distance to the walls on the left and front. Based on those readings, the Arduino decides whether to move straight, turn left, or pivot right—always keeping the left wall as its guide. You’ll end up with a working bot that can complete a hand-drawn cardboard maze or a printed track, demonstrating the power of sensor-based decision-making.
What You'll Learn
- How ultrasonic sensors work and how to read distance data with an Arduino.
- Controlling DC motors using an L298N motor driver and PWM signals.
- Implementing a left-hand wall following algorithm in C/C++ (Arduino IDE).
- Assembling a 2WD robot chassis and calibrating sensor placement for reliable navigation.

Who This Kit Is For
Perfect for ATL Tinkering Lab students, CBSE Class 6-10 science exhibition participants, and first-year B.Tech ECE/EEE learners at VIT, BITS, and NITs. Young makers aged 10 and up will find the step-by-step AI guidance intuitive, while hobbyists who want a quick, working robot platform will appreciate the pre-tested parts and clear documentation. If you’ve ever watched a maze-solving video and thought “I want to build that,” this kit is your starting line.
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.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion, which gives real-time debugging help specific to this kit. You can also message us on WhatsApp for human support within 24 hours.
What kind of maze can this robot solve?
It works on any flat maze with walls at least 5 cm tall and corridors wide enough for the robot to turn (about 15 cm). Cardboard, foam board, or printed tracks all work well. The left-hand rule solves any simply connected maze.
Do I need prior Arduino coding experience?
No. The AI companion provides fully commented code and explains every line. You’ll learn as you upload, and the logic is beginners-friendly.
Can I modify it for a right-hand wall following competition?
Absolutely. The code is open, and the AI assistant can help you switch the algorithm—just change a few sensor priority lines and test. The hardware supports both strategies.
Left-hand wall following algorithm with two HC-SR04 sensors navigates through a simple maze autonomously.
