Animatronic mouth

Hello to all. I hope I’m posting in the correct forum? I’m completely new to anything like this, but I watched a YouTube video youtube.com/watch?v=ug8yfIa26uI and would really like to know how to make this. Can RC be used and how are vocals added?
I would be very grateful if anyone can help.
Thanks in advance.

Hi Dave,

Here are answers to your questions and comments:

Yup! :slight_smile:

That setup basically has one RC servomotor and most likely some kind of power source (typically 4.8-6.0 V DC, some go as high as 7.2 or 7.4 V DC) and a controller. The controller can be a microcontroller board (such as an Arduino) or a specific RC-type servomotor controller board, like the SSC-32U RB-Lyn-850].

We assume you mean a typical RC transmitter/receiver pair like what is used for RC planes/cars/copters/etc.? If so, then yes, you can use that directly. The RC servomotors can are meant for that type of control signal. You will still need a battery or other power source at the right voltage level (and current capacity for your setup) and also something for your vocals, though (see below).

This would be done using either speech synthesis hardware (ex: RB-Plx-277, RB-Dfr-552) or simply playing back audio that is pre-recorded (check audio synthesis equipment here).

We hope this helps.

Sincerely,

Thank you all for these replies. Are you OK if I continue posting when I come across any difficulties?

Hey Dave!

Please do and we’ll help as much as we can. We won’t be assisting with design work for your project, but we are happy to help guide you towards the right direction and clear up any confusion about what products to use and such.

Sincerely,

To all again. I’ve bought a 9G SG90 Micro Servo motor RC. I’m hoping this is the right one? Could you also tell me about controller boards please? The ones mentioned, how do they work? Which would should I buy, for my project?
I’d be grateful for any information
Thanks
Dave

Hi Dave,

The simplest to get started might be an Arduino-compatible microcontroller board, such as the Arduino Uno. The SSC-32U is a great product for controlling multiple RC servomotors with tight timing requirements. That being said, it is most definitely too much functionality for someone starting out with a simple project.

You may want to look at these blog articles. They cover most of the basics and should help you get a good idea of what knowledge you are missing (so you can hunt it down :smiley: ).

Since a servomotors can use quite a bit of current (when compared to microcontroller), it is recommended that you power them directly (and not through the VCC of the microcontroller board). If you use a 6 V DC high current power source for your microcontroller board, you can usually access the input on the board. For example, on a Arduino Uno microcontroller board, you can access the barrel connector’s V+ at the Vin female header and the V- at GND headers. In such a case, you would connect the RC motor’s VCC and GND to Vin and GND on the Arduino board.

Sincerely,
