What is Animatronic Beaker-bot? Well, the Beaker-bot is a animatronic puppet that will "sing" to the sound that I play through him. Meaning, If I hook up an iPod or other music playing device, he will lip-sync his mouth to the music or words. He is also a fully functional puppet with Beaker style head and hand control. He also has a electric button to control his animatronic mouth, and for fans of more classical puppetry, Beaker-bot does have a classic rod to control his mouth as well.
Beaker-bot, for me is both an excellent puppet for someone like me who does not have good enough puppetry voice skills to talk on my own. I also can have him on display, and he can talk and sing without a puppeteer, which is one of the major advantages of animatronics. I plan on having him on display during holidays such as Christmas.
I better mention right here that this is my first attempt at anything puppet or animatronic related. I am very happy with the results for my first try. I have no clue what the professionals use in their methods, and I am pretty sure that the methods I use are not the same as what is done professionally. That being said, the methods I used turned out very well for my needs.
Here is a demonstration on Beaker-bot's automatic speaking and singing abilities:
I had a demo of Beaker singing some songs here, but I decided to move it to the last page as a finale. Feel free to cruise to the last step to see Beaker singing! I also have a demonstration of using Beaker-bot for traditional puppetry. Beaker has full head rotation and can duck his head as well.
Here are a few ideas of what to do with the Beaker-bot:
- Dress him up for holidays and have a memorable singing decoration
- Have a Fun prop to display
- Play pranks and jokes
- Learn about puppetry and gain new skills
- Hook up to Karaoke machine for added singing fun
- Set him up to play with your music collection
Step 1: Parts and Tools: Can We Build Him? Yes We Can!
Parts I used for Beaker-bot's Head:
3 Inch PVC drain pipe
2 Plastic Christmas ornaments
1 Plastic Easter egg
White and black paint to color eyes
Orange feather Boa
Orange felt for nose
Pink fleece for skin and hands (Peach can be used as well)
Parts I used for Animatronic Mouth:
1 Douglas Fir singing tree (This is the "brain" used in Beaker-bot)
Plywood for mounting motor and for mouth motor plate
Audio cables with RCA ends and 3.5 headphone jack ends
Old handle from sawplade
Nintendo NES reset switch
2 flat metal plates
Wood dowel for rod mouth movement.
2 Ice cream bucket lids
Parts Used for rest of Beaker-bot
4 inch PVC pipe for moving collar
Plexi material for stop bar on collar
Old lab coat
Old shirt and tie
Hot glue gun and LOTS OF HOT GLUE
Saw to cut PVC
Dremel rotary tool for complex cuts
Sandpaper or sander to smooth cuts
A good clamping workbench
Printer to print face template
Step 2: Eyes and Nose Made From Holiday Decorations
The nose if far more complicated. An egg was not the perfect shape to use for beakers nose because his is longer. I used putty to fill in the back of the nose, but I wish I had something that would work better like Shapelock. The putty did not adhere to the glue at all, so it took a lot of work to get it working, and even then I had to reapply glue a number of times before the felt would stick. In the end, I made the nose look nice enough, but I might redo it at some point.
What I did was take felt and stretch it tightly over the egg. Then I laid down hot glue section by section, pulling the felt tight over each hot glue application. When I had felt overlap, I cut the felt and glued the seams tightly together. After roughing up the seams and cutting away bulges, it is hard to tell where the seams are. I still put the largest seam on the bottom of Beaker so it is even less noticeable.
All I can say is that if you need to make a nose, Start with a practice one. I took me a while to get the process down and I dont think I would have been able to do it very well on my first attempt.
Step 3: Cut the Head and Mouth; Sometimes Chopping Off a Head Is a Good Thing.
Then, I tape on graph paper and measure up the eyes and nose on the paper. From that I can draw up a good looking mouth.
I then take my graph paper and make a vector image of his face so I have a smooth shaped mouth, I cut the mouth out from the vector, tape it on the pvc pipe, and measure out and cut the mouth using a dremel tool.
Step 4: Time to Trim the Tree: Parting Out the Douglas Fir
The mouth is screwed in, so unscrew and pull out the mouth motor. This will also be Beaker-bot's Mouth motor as well.
Now remove the PCB board from the tree base by unscrewing it. There are a number of wires on the board, but many can be removed. The wires that go to the tree's motion and sound sensors can be clipped completely. The wires for the eyes can be clipped as well. Save those eyes for another project!
Now the speaker can be clipped off, but we want to solder an RCA female jack on the wire, then we can have an audio out to any source.
Now it is time to place the PCB in it's new case. Using 2 ice cream lids that snapped together, I glued the pcb on the inside of one lid, and cut a hole for the access panel. The other side will be there to protect the PCB. This will serve as a lightweight housing for beaker-bot's electronics. This will be hidden under his clothes.
Step 5: Make Beaker-bot a Real Motor-Mouth
What happens in the mouth is that when the PCB board reads a certain decibel and range of audio run through it, it triggers the motor to move. The motor then swings up, pushing up on the strap hinge. This hinge mechanically adjusts the motion to an outward swing of the mouth. A spring loaded wire returns the motor back to its starting position when not triggered.
I made a wood platform for mounting the motor, and glued that in place. Then I glued on the motor and added a white hollow sleeve to allow for rod movement. That way power is not required to make beaker-bot's mouth to move. On the motor arm, I made a wood platform to push up and down on the strap hinge.
Here is my first demo test of the mouth in action:
Step 6: Skin Beaker-bot
Now after the mouth area is done, stretch out the rest of the skin and glue on. you want the skin to be taught, but not tightened to it's limit. now cut and glue the back seams just like the nose.
Now with the skin on, you can test fit the Eyes, Nose and Hair. Take them back off for now, they will only get in the way.
Step 7: Hands, Hands, Fingers, Thumb
Now take two cutouts and stitch around the perimeter of the hand. When done, fold the hand inside out and you should have a beaker style hand. This can be sewn directly into the sleeve of the lab coat.
Step 8: Clothes Make the Beaker-bot
Start by cutting about a 6 inch section of 4 inch pvc piping, this will be beaker's collar.
Place it on an upright pvc so you can work with the clothes in a natural way. Now start with the collar shirt underneath. Hot glue it around the perimeter of the pcv pipe.
Next, put on a tie. Clip on ties work great. I chose a bow-tie for Beaker-bot. Why? Because bow-ties are cool.
Now put on his lab coat with the gloves sewn in. After that, place down hot glue to keep things like his lab coat collar in place. Use a photo as a guide to make sure he looks true to life. You can cut slits in the back of the arms of the Lab coat so you can slide in your arm, and ultimately control Beaker-bot's hands.
Step 9: Don't Lose Your Head!
Step 10: Get a Grip!
Then screw on a metal bracket and epoxied that on to the bottom inside of Beaker-bot's head.
Now, take the wood dowel, and slide it up into the head and into the rod-guide sleeve by the motor. Cut the dowel to a comfortable length to operate. Take some spare fleece or felt and glue it on one end as a handle. You can put material on the saw blade handle as well.
Step 11: It's Alive! the Final Electical Work
Hot glue straps on the PCB case and then glue the straps on the back of the shirt. This will keep all wires behind your hand for when using Beaker-bot.
Step 12: Attach Nose, Eyes and Hair, and You Have Yourself a Beaker-bot
Here is a fun little clip of the Finished Beaker Singing.
Last, if you want to make a stand for Beaker, just take a section of leftover 4 inch pcv, and prop in upright on a piece of wood., Then place shoes down and it will look like Beaker is standing. You can see my first video on step one to see the PCV Stand in action.
