Multipost barrier strip. robot to be wired together with great ease they also allow you to remove individual components from the robot without disturbing others. Most of Questor s electrical components use barrier strips. For now you need only three barrier strips two 2-post and one 8-post. These two 2-post terminals are permanently mounted on the platform near where the motorized wheel post protrudes through the platform the exact location is of little importance. The third 8-post strip will be temporarily mounted at the center of the rear edge of the robot s platform. It will be removed later for use in the remote control system. WIRING PLATFORM Now that the power supply and barrier strips are mounted they must be wired together using 18-gauge wire. This wire will be used now and throughout the robot. Figure 3-5 shows a graphic representation of how the platform is wired. when you look at Fig. 3-5 you will notice that all the wires used are either red or black. The red wire represents all the wires that will eventually be connected to the positive pole of the power supply and the black to the negative pole. While Fig. 3-5 is rather straightforward a few things must be noted before wiring can begin. First the red and blue wires coming from each of the motorized wheels must be connected to their barrier strips. The wires from each wheel are too short and must be extended 44 Chapter Three FIGURE 3-5. Platform wiring diagram. using one 6-inch red and one 6-inch black wire for each wheel. Use twist caps or solder the red extender wire to the red wire of the motorized wheel and the black to the blue wire. To connect the extended wire to the barrier strips twist both wires loosely together and push them up and out of the post of the motorized wheel. This post leads to the inside of the lower framework where the barrier strips are placed. Connect the wire to two of the screw posts on the same side of the strip. Refer
