CHAPTER FIVE
THE HEAD
Questor’s head is basically an automobile dome light with a
white cover made of ceiling light panels. The dome light is
attached to a 9 1/2-inch-square piece of 1/8-inch pressboard
(or plywood; hardboard is easier to cut circles in) which is in
turn mounted at the top of Questor’s upper framework using
three predrilled holes located on the framework. Three metal
tabs located where the light’s base is screwed to the frame-
work act as mounting points for the light’s cover. Figure 5-15
shows the dome light and cover mounting tabs attached to the
robot’s frame.
The mounting tabs for the cover are made from the same
type of sheet metal used to make the container brackets for
the drink dispenser. The tabs should be 2 inches long folded
in the middle with a 1/8-inch hole drilled at both ends. Note
that the holes drilled in the ends of the tabs should be slightly
smaller in size than the diameter of the 1/8-inch sheet metal
screws used to hold the dome light assembly to the robot’s
frame.
The dome light cover, which is actually considered
Questor’s head, is made from a sheet of plastic ceiling light
