later in this chapter. Also note the rubber gasket around the
vacuum cleaner motor that you can attach at this time.
To mount the pots and switches, poke a hole through
the front of the panel folding the excess sheet metal against
the inside of the panel. It is then a simple matter to mount
the components in place by attaching them to the panels
using the nuts that come with both the switches and pots.
You can, if you wish, buy knobs for the pots, but it is not
necessary.
Also mounted on the rear panel of the lower framework
are the two charging plugs for Questor’s batteries. These
plugs needed a firmer base than the metal flashing can pro-
vide. For this reason two 6-inch strips of aluminum angle are
riveted vertically at either side of the framework behind the
body panel. The plugs are then fitted between the side of the
framework and the support strip utilizing a ridge that goes
around the plug. A small square must be cut in the lower
corner on either side of the panel to accommodate the plug
as seen in Fig. 6-10.
The next two items are the on/off switch and recharge
plugs for the remote control system. The on/off switch is
mounted at the lower edge of the right side panel of the upper
framework. Follow the mounting directions that come with
the RC system and use the hardware that comes with the
switch. The RC charging plug is taped to the lower edge of the
back framework itself; I used duct tape because it had a
metallic look that matched the framework. Both mountings
are shown in Figs. 6-11 and 6-12.
The last item to be mounted is the on/off switch for the
auto dome light in Questor’s head. Mount it on the same side
as the on/off switch for the RC system, but at the top edge of
the framework, as shown in Fig. 6-13.
Once these eight components have been mounted,
Questor is basically complete. The rest of this chapter is
devoted to adding items to spruce up the robot’s appearance.
Also, if you have purchased an RC system with a third channel,
you will be adding a horn that is controlled by the system’s
third servo.
