Brand new here and new to animatronics, but I love a good challenge.
I've built puppets for years and even a few ventriloquist dummies.
I've always wanted to make something like the duloc information booth from shrek, only with an original theme.
I sketched this up. I have 2 plans of action on where I want to go with this:
The ideal one is to actually have animated puppets. Little ones with the up and down moving mouth only. I want to keep it simple. It will be contained within one window. The machine is operated when a coin is inserted into a coin slot. It doesen't vend anything it's mainly the musical number and the singing freaky looking puppet/dolls.
Plan B (this particular sketch) is with a video monitor and a pre recorded video. It pretty much explains it in the sketch notes. I'll sketch up plan A at some point too. The animatronics plan B are a gumball mech that dispenses a gumball when the video is finished playing.
I have a raspberry Pi, and building skills. Programing is not my strong point to say the least. I know i need servos for this, But I need all the help I can get.
If anyone can help me figure either plan of action out, let me know. Plan A is preferable but as someone who never did an animatronic before Plan B can work too. But I love a challenge.
Cool project! I don't have a lot of Rasp Pi skills (just started playing with it) but I think both plans are totally doable. For Plan A it appears you need a mechanism to move the mouth up and down sort of in sync with the music. Basically I think you could use a sliding rod within a tube in the lower body to achieve this. The tube would need to be slotted and have a pin in it so the rod wouldn't rotate. You could have a servo or a solenoid move the rod up and down.
I think I saw something where someone took the speaker output from a small sound board and used that as an analog input for an arduino. Then the input value tells the output pin when to trigger on and off. So with a solenoid the audio file would play and the arduino tells the solenoid when to pop the head up according to the music- similar to making an LED flash with music. With a servo driving the head I think you could have a bit more control.
