We already know that we can set the velocity of the motor and the amount of time we want it to move. What we can't program with the known commands so far is how much we want the motor to turn. For the motor to turn at a specific amount of degrees, we need to use some math.

The speed of the motor is set as degrees per second and we can use this to calculate how much the motor will turn using the following formula:
S = V * T
S = The travelled distance (in our case the amount of degrees the motor has turned;
V = Velocity;
T = Time;
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
Python with LEGO Mindstorms EV3 - Level 1
The course introduces students to the programming language Python. We use LEGO Mindstorms EV3 Robots. Python is a popular programming language. It could be used for introducing students to programming, for academic studies, for developing machine learning algorithms and as a general-purpose language.
During the course, students learn how to read and how to develop Python programs. They use an Integrated Development Environment called Visual Studio Code. Robots are programmed to perform interesting and funny tasks like "bringing you water". The level ends with competition on a playing field with boxes.

Lesson 2 - Robotic arm
Introduction
Last time, we programmed our robot to walk around with a platter and a beverage glass, but it couldn't hand the glass to a client. Today we will program a robotic arm to hand out a glass.
Be careful with what speed you will set your robot to move the glass or you may spill its contents!
