Encoder Robot Kit with Arduino Uno: Auto-Calibrating for 1% Straight Line Accuracy

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

You'll build a two-wheeled robot that automatically calibrates its own wheel diameters using LM393 speed sensors, then drives perfectly straight lines with less than 1% deviation. The kit turns a typical 2WD chassis into a self-measuring mobile platform that compensates for motor variance, tyre wear, and floor texture - all without manual tuning. Every startup becomes a fresh calibration cycle, so your robot stays accurate across sessions.

What You'll Build

A self-calibrating mobile robot that learns its physical wheel sizes on power-up. The LM393 encoders feed pulse counts to the Arduino Uno, which computes exact wheel circumferences from a short reference movement. You'll see speed and odometry data in real time on the 0.96-inch OLED. Once calibrated, the robot holds a straight line over one metre with sub-1% lateral drift, making it a reliable base for delivery bots, mappers, or competition-grade line followers.

What You'll Learn

• Interface LM393 speed sensors with Arduino Uno to capture wheel rotations
• Implement auto-calibration algorithms that measure wheel diameters from actual displacement
• Use encoder feedback for closed-loop motor control with the L298N driver
• Display velocity, distance, and calibration status on a 0.96-inch OLED
