Robot Programming Basics

What is it?

Robot programming is the act of writing software that reads sensors, decides what to do, and commands actuators. Whether you're using Scratch on a microbit or C++ on a humanoid, every robot program shares the same loop: sense → think → act.

How it works

Every robot runs a main loop that, at each iteration, reads sensors, computes a decision (usually through a controller or planner), and writes actuator commands. Beginners typically start with simple loops on Arduino — while(true) { read_sensor(); decide(); write_motor(); } — and graduate to event-driven systems, then ROS2.

Real-world example

Indian school robotics teams writing their first line-follower learn this loop. Engineering students build their first PID-controlled balancing robot on Arduino. Final-year projects move to ROS2 + Python.

Why it matters for robotics

Robot programming is the gateway skill — once it clicks, every harder topic (kinematics, perception, AI) becomes accessible. Start small, iterate fast, and build something that moves.
