Large manufacturing companies have big dangerous machines that check if it's safe to begin operations. These machines don't check if there's someone, rather if there is no one in their working environment in order to execute their operations.

Such conditions can be described using the "not" operator. The way this operator is used is by placing it before the condition you wish to check if it's unmet.
Here's what this operator should look like when used in an "if" operator:
if not condition: (code for conditional execution)

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 2 - Grabber control panel
Introduction
Today we will create a robot that you can control with just tha press of a button. It will detect when you have pressed the button once and when you've pushed it twice. Based on this, it will either open or close its pincers and the objects within.
In this lesson, as well as the next one, we will be building a control console: first for the pincers, later for a crane. We will be looking at the sensors as a means of human interaction with the robots before we make autonomous robots with them.
