Build Real Robots.
Step by Step.

Two LDRs and a servo team up so your robot tracks the brightest light source in the room — like a sunflower with wheels.

Build a robot that follows a black line using two IR sensors, an L298N motor driver, and an Arduino — your first taste of sensor-driven decisions.

Use an HC-SR04 ultrasonic sensor to detect walls before you hit them, then turn away — the foundation of every autonomous robot.

Drive your robot from your phone over Bluetooth Serial — your first wireless control system using HC-05 and Arduino.

Wall-following plus recursive backtracking — your robot learns to escape any maze, the same algorithm Theseus would have used.

Three SG90 servos, a desktop chassis, and your first hands-on lesson in forward and inverse kinematics.

An MPU-6050 IMU, a PID loop, and two wheels — meet the inverted pendulum that taught Segway how to stand up.

Ditch the IR sensors. Use a Raspberry Pi, a camera, and OpenCV to actually see the line — your first real computer vision project.

Build, map, and navigate inside Gazebo using ROS2 Humble and Nav2 — the same stack production warehouse robots run.

YOLOv8 detects objects in real time, a 4-DOF arm picks them up and sorts by class — your first taste of industrial AI robotics.
