1. Understanding Icons

Writing programs is easy.

It involves stringing icons together in a particular sequence or order. Together, all the icons make up the program.

The order of the icons in the program depends on what you want the cart to do.

Each icon represents a particular instruction so that program become a collection of instructions to the robot.

Designers of Robolab have tried to create icons or pictures that look like the function they represent. Understanding the meaning of these icons will greatly improve your programming skills.
