The LEGO MINDSTORMS EV3 Discovery Book (Full Color)

Chapter 2. building your first robot

In Chapter 1, you learned that EV3 robots consist of motors, sensors, and the EV3 brick. To make it easy for you to understand how each of these work, you’ll begin with only some of them.

In this chapter, you’ll use the EV3 brick and two Large Motors to build a wheeled vehicle called the EXPLOR3R, as shown in Figure 2-1. You’ll also add a receiver for the remote control. After you finish building the robot, you’ll learn how to navigate the EV3 by using its buttons and how to control your robot remotely.

Figure 2-1. The EXPLOR3R moves around on two front wheels and a support wheel in the back.
