building your first robot
In Chapter 1, you learned that a robot consists of several important components. To make it easier for you to understand how each of these works, you’ll begin by working with only some of them. Specifically, you’ll first learn to work with the NXT motors and the brick as you build a wheeled vehicle (the Explorer, shown in Figure 2-1) that can drive around your room. Once you’ve built the Explorer, you’ll do a quick test to see whether you’ve correctly assembled the robot and to make it move!
building the explorer
To begin, select the pieces you’ll need for the Explorer by referencing the bill of materials shown in Figure 2-2. Then, assemble the robot as shown in the step-by-step building images on the next pages.
