To secure the ultrasonic ranger to the robot, a housing to mount
the unit will be fabricated. Use Figure 7.18 as a guide to cut, drill,
and bend the housing, using 1/16-inch thick aluminum. Drill the
mounting hole with a 5/32-inch drill bit. The aluminum can be
bent on the edge of a table by hand or in a table vise. Figure 7.19
shows the finished housing so that you can get an idea of how the
aluminum should be bent. Next, place the ranger unit inside the
housing at the front and secure it in place by tightening the alu-
minum around the circuit board by hand. Apply a small amount of
hot glue on the inside at the corners where the circuit board and
aluminum housing meet. This will ensure that the circuit board
does not move out of position.
