Introduction to the LEGO set

A simple LEGO robot looks just like that:

Figure 1. EasyBot

Before we begin construction, we will take a look at some of the parts of the robot.


Large motors

Figure 2. Large motors

These are the "legs" or "muscles" of the robot. There is also another type of motors called medium but we will introduce them in future lessons.


Microcontroller (Brick)

Figure 3. LEGO EV3 Brick

LEGO calls that part "the intelligent brick". You can think of it as the "brain" of the robot. However, it is actually a microcontroller or a small computer where you can upload the programs you have created from a regular computer. Then, based on the programs, the brick can read data from the sensors and operate the motors.


LEGO Technic parts

Figure 4. Some of the main LEGO Technic parts in the LEGO Mindstorms EV3 set
