Time to be a Scriptwriter
Your first step in selecting the proper trigger is to
determine exactly how you want your character to interact
with your guests.
Will you have attendants or actors available that can
monitor the scene your character is in? How accurately can
you predict the location of your guests? Will there need to
be delays between activations? Is your character located
inside or outdoors? Will it need to perform at night, during
the day, or both?
These are all important considerations to take into
account when planning your prop’s activation schedule.
What are My Choices?
Once you’ve choreographed your character’s
performance, it is time to decide on your activation
method. Let’s look at some of the alternatives available and
the merits of each one.
A Microprocessor Can Do It
One option is to program a microprocessor to trigger
your routine on a timing loop. Set a retrigger delay and
allow your character to perform at regular intervals. This
method is especially useful if you have people in line
moving past your display at a calculated speed. You can
What do you do if you don’t have someone to trigger your props on
cue? Do you throw up your hands? Are you out of luck? Well have no
fear, the answers are here!
You have put in long hours dreaming up, designing, and building that
special one-of-a-kind animatronic. Now, you need a method to control it
to respond at precisely the right time and perform on demand.
There is a wide variety of options to choose from when selecting the
best trigger mechanisms, but no single solution is best for every
situation. I know this is not the most glamorous part of the build
process, but they perform a vital role in creating the illusion we are
attempting to create.
We will examine some of the options, and I hope to introduce some
products that may be new to you. Take a look and you may discover a
useful technique that will improve the performance of your designs.
