Robotics for Students — From First Robot to Final-Year Project
Robotics combines mechanics, electronics and programming. A student robot typically needs a chassis, BO gear motors, an L298N motor driver, an Arduino or ESP32 as the brain, and sensors (ultrasonic, IR, MPU6050) for perception.
Building your first robot is the fastest way to consolidate everything you learn in electronics. Start with a two-wheel obstacle avoider and progress to line followers, self-balancing robots and Bluetooth-controlled cars.
Parts you need for a basic robot
- 2WD chassis + caster wheel
- BO gear motors × 2 + wheels × 2
- L298N motor driver
- Arduino Uno or ESP32
- HC-SR04 ultrasonic sensor
- 9V or Li-ion battery pack
- Jumper wires + breadboard
Why do I need a motor driver?
Microcontroller pins deliver only ~20 mA. Motors need hundreds of mA. A driver like L298N uses external power to drive motors while the MCU just controls direction and speed via PWM.

Frequently asked questions
Do I need to know coding for robotics?
Basic Arduino C is enough for 90% of student robots. You call motor.forward(), read sensors, and make decisions.
Which motor driver is best for beginners?
L298N — cheap, reliable, drives two motors, well-documented in every tutorial.
