How this system is used to control Questor will be described later in the chapter. CONTROL BOX CONSTRUCTION The temporary control box will house all of Questor s control electronics in this stage of his construction. The box itself should be approximately 4 X 4 inches square to allow room for the various parts. The parts contained in the control box are two heavy duty DPDT switches and two potentiometers like those shown in Fig. 3-8. These components are wired together in the control box then connected to the robot s batteries and motorized wheels via a group of wires taped together in a cable. How the parts are mounted in the control box is up to you however Fig. 3-9 shows a recommended layout. To mount the parts you will have to remove the box s overplate on the control box and drill mounting holes in that plate. WIRING THE TEMPORARY CONTROL BOX The wire used in the temporary control box and throughout the robot is an 18-gauge-type colored either black or red. Again red is for all wires connected to the positive pole of the batteries and black is for all to the negative. This makes it easier to trace FIGURE 3-8. DPDT and pots switch. Power Supply and Temporary Control Box 49 FIGURE 3-9. Suggested control box layout. the various circuits in Questor. The robot s electronics are not so complicated that you would confuse these wires with others leading to Questor s various systems. Figure 3-10 shows how to wire the components in the control box together. The color of each wire has been noted. Try as I might I was unable to make Questor a completely solderless project. You will have to solder some of the robot s components. Two of these components are the pots in the control box. If you have never soldered before you could simply twist the wires around the post of the components but this makes for loose and many times poor electrical contacts. what you can do is twist the wires now and solder them later when you have .
