Python with LEGO Mindstorms EV3 - Level 2
In the second level of Python for EV3 robots, students learn in-depth the touch sensor. The sensor is used as an input device for manual control of machines, as well as a sensor for autonomous robots. In a pair of lessons, students build a control panel for the grabber and the movement of a crane. Programming wise, students learn how to fork code with "if-else" constructions, how to create conditional and forever loops with "while" and how to negate conditions with "not" operator. In the end of the lesson, robots can detect obstacles and avoid them, so that they traverse a simple labyrinth.

Lesson 1 - Security system.
Introduction
In this lesson, we will create a system that checks if the exit of a supermarket is closed or if there are still more people in the building. In big supermarkets, security guards must reassure that all of the clients have left the premises before they've locked the door.
However, there is always the odd case of someone getting locked in by accident, which is why there are security systems that notify the security guards they have made a mistake.
