To build the frame of the robot I used hobby plates and brackets that I got from Lowe's. Figure 0 shows three of the style parts used to build the frame. There were various designs that I came up with but the best one is the one that can be seen in Figure 1.

The platform that holds the BeagleBone Black is a perfect size for holding a mini-breadboard. I will need the breadboard to add components such as resistors and buttons. It also will make connecting the servos and the IR distance sensor a lot easier. See Figure 2.

For the IR distance sensor I had to make a voltage divider circuit because the analog pins on the BBB can only handle up to 1.8 V. To make sure I was not going to brick my BBB I connected the IR sensor to a multimeter to check the voltage divider circuit in Figure 3. The voltage divider never went over 1.6 V on the multimeter so it should work.
