Step 6: The Controller Software

Visual Show Automation is used to choreograph the servo movements with the sound.

First thing is VSA configuration. The Tools/Settings menu brings up a dialog box listing the configurations for all tracks. Change the type to "Parallax Servo" & set the port number. Change the address to match the channel that the servo is plugged into on the Parallax board. You can give a descriptive label to the track, like Eyes, Jaw, etc. Check the baud rate under Port Settings & make sure it's 38400 for the Parallax board.

The +Value, -Value, & Default set the limits of the servo, and the default starting postition.

VSA has a useful tool called "WaveMotion Analysis" that can automatically generate events from the volume of an audio file (This is why we saved each voice in it's own wav file). Load each voice track & generate control events for the appropriate servo.

Afterwards, load the combined audio track.

excellent job !!!!!
Very nice animatronic, do you think it is possible to hack a portative voice modifier to create a jaw moving big talking mask ? I have a project to make a furry mask with your method, but I don't know how to transmit the input of the voice modifier to the servos.
Check this out it takes sound input and puts it into servo movements!http://www.scary-terry.com/audioservo/audioservo.htm
Here is a much better software (free) that works great! <a rel="nofollow" href="http://www.robokits.co.in/downloads/USB16Servo.exe">http://www.robokits.co.in/downloads/USB16Servo.exe</a><br/>
The Parallax USB Servo Controller was discontinued and is out of stock. would the serial one work? also im trying to do this "on the cheap" so is there another free or cheaper software I could use? Thank you!
There a reference to other controllers at the BrookShire site:<br/><a rel="nofollow" href="http://www.brookshiresoftware.com/rd_how_sscs_work.htm#parallax">http://www.brookshiresoftware.com/rd_how_sscs_work.htm</a><br/>They mention the serial controller will work, but may need additional circuitry...<br/><br/>If you only want to control one or two servos, you might be able to use an <a rel="nofollow" href="http://www.arduino.cc/en/Reference/Servo">http://www.arduino.cc/en/Reference/Servo</a>, but you'll have to roll your own control software.<br/><br/>Sorry I haven't tried any other software (yet!), but I'd be interested if you come across any.<br/>Good luck, and let me know how things go!<br/>
<a href="http://www.instructables.com/group/Halloween_Scream/">http://www.instructables.com/group/Halloween_Scream/</a> Can we add this to my group?<br/>
bwahaha, mask of dane cook+animatronic parts= tons of laughs!!!!!<br/><br/>hahahahahahahahaha<br/>
Does anybody know where to find that skull??
Bought it at a local Home Depot before Halloween last year. Looking back, I wish I had picked up several!
This is great! I love the step about syncing the sound and motion.
Thanks! That's one of the most fun steps, 'cause that's where thing's really start to come alive.
Greetings from <a rel="nofollow" href="http://AnimatronicsWorkshop.com">The Animatronics Workshop</a> ! You have a very cool display. I'm so glad we could help inspire you. As you know, we're just some parents trying to make a difference in our schools, and we think animatronics is a great alternative to the traditional robotics programs. So now that you know how easy this was to do, go tell your local schools that they should look into it...<br/><br/>--- paul<br/><br/>P.S. One extra tip: you can make the mouth movements look even better by playing with the dialog tracks. The problem is that lower volume areas hardly cause any motion. Just normalize these up in Audacity before running WaveMotion Analysis. Remember to keep an unaltered version for your combined track that you actually listen to...<br/>
Thanks! We all had a lot of fun and are already looking forward to our next animatronic creation.<br/><br/>There's definitely some problem areas where there was little or no mouth movement. That's a great tip for improving the dialog movements -- it didn't occur to me to do more pre-processing in Audacity. <br/><br/>And again, thanks for all the work you guys put into <a rel="nofollow" href="http://animatronicsworkshop.com/">The Animatronics Workshop</a>!<br/>
very cool...:)
