First, install the libraries to support the motor control board, described in the second chapter. Since this robot uses the same control as the wheeled vehicle, you'll use the same code for the simplified library that you used as a library in the second chapter, as shown here:
The following is the simple code to exercise this program using keystrokes on Raspberry Pi:
Run this program by typing sudo python input.py. If you get an error message telling you that the program does not know about rr=RRB2(), you'll need to copy the rrb2.py file from your installation of the libraries for the motor controller board in the directory rrb2-1.1.
Now that you can control your wheeled robot from the console, let's connect it wirelessly to allow remote control.
