Picture of FRITZ - ANIMATRONIC ROBOTIC HEAD

Hey guy's welcome to my instructables let's make.

Fritz -The Animatronic Robotic Head.

Fritz is open source and awesomely amazing.

It can be used for anything.

Ex: learning human emotions, receptionist, Halloween stud, flirter, singer and much more all relies on your imagination!

It can also sing songs and the best of all it has a changeable base plate so you can etch anyone’s face on it and attach to Fritz and Fritz becomes your man.

I have made two versions acrylic and plywood.

I wanted a stoned look so my friend painted my acrylic Fritz eyeball showing red nerves.

Apply some glue if required.

Step 36: Give It Brains.

Picture of Give It Brains.

Below is the zip file containing arduino code and software for fritz.

Also contains the source code of software if someone wants to recompile it or make some changes.

Upload the “fritz.ino” code to your board.

Now close “Arduino ide” otherwise fritz app won’t connect.

Now open “fritz.exe”.

You should see a green tab indicating “CONNECTED” this means fritz is read to rock n roll.

Now go to “options>setup motors” and change ever field to “0” this step centres our servos automatically.

While changing to zero if you get a screen "error in simulation paint overflow" do not press ok press the “X” button otherwise the screen will pop-up again and again.

Press “OK”.

Restart fritz app.

Please do this step it is very much required otherwise our servo will start buzzing.

Change the control tabs to whatever you want.

I connected this way.

2-left eyelid.

3-left eyebrow.

4-left horizontal eye.

5-right horizontal eye.

6-left lip.

7-right eyelid.

8-right eyebrow.

9-right horizontal eye.

10-right vertical eye.

11-right lip.

12-twist neck.

A0-tilt neck.

A1-jaw.

A2-ultrasonic echo pin.

A3-ultrasonic trigger pin.

A4-ir sensor.

Press “OK”.

Now connect base motor, i.e., twist neck to 12 pin.

The motor will self-enter.

Now attach neck assembly on top of it.

Carefully press it on top of the base motor secure with screw.

Now attach neck servo motor, i.e., neck tilt to A0.

Motor will self-center.

Now get the assembled face align the gear in the face with the neck gear.

Pass rod or wooden dowel through and through till the other end.

Now attach jaw motor the motor near the chin part to A1.

Mount the jaw assembly over it such that the mouth is closed secure the servo horn with screw.

Now connect all remaining motors to the board.

While connecting remember.

Inside the eye box the motors place vertical are “eye horizontal motors” and the motors place horizontal are “eye vertical motors” the motor on the left is “right eyelid” motor and the motor on the right is left “eyelid “motor.

All will enter themselves.

Attach all servo horns and secure with screws.

While attaching the eyelid servo horns notice that the eyelids are half open.

Attach the face plate.

Secure with nut-bolts.

Attach the eyebrow motors when they center add the eyebrows and secure with screws.

Attach lip horns on both sides.

Attach two springs one for top lip and other for second lip secure with spring.

Tie the centre of upper lip to the small hole on face plate.

Tie the centre of lower lip to the small hole on jaw.

Step 37: Getting All Ready.

Now go to “options>setup motors”.

Press the minimum and maximum arrows so as to move the individual parts.

You should see the parts move in conjunction with the values.

Adjust each values for each movement press the test button when done one satisfied press the stop button.

Now uncheck the box which you finished setting so that you accidentally don’t move the parts too much to break them or someone doesn’t hack your face.

Set each and ever part and uncheck the boxes.

If you have an ultrasonic sensor or analog ir sensor attach anyone of them and you should see the value range.

Press ok when done. .

While changing to zero or whenever if you get a screen like this do not press ok press the “x” button otherwise .the screen will pop-up again and again.

These are my set of values.

Now move through the expressions on the left.

You will see the animation and our fritz move together.

Tadaa!! Fritz alive!!

Step 38: Software Overview.

Hover over the animation you will see green dots.

Click and drag those dots you will see the animation and fritz moving.

Dots resemble individual parts.

Got to “file>load audio” load a song in .wav file click on play.

Fritz will start singing.

Click on “edit” and you can cut trim the audio file and do much more things.

Load movements on top of your audio file.

So fritz sing with action!!

You can also trim paste and do lot to everything.

Edit also has a record window where you can record movements, save and play them later.

You can open preloaded sequences.

Also make one by moving individual parts and save them for later use.

Go to “behaviour” you have two options “face detect and greet” , “tell me the temperature”.

For this options to work you need to install “robo realm” machine vision software.

The last option “random messages” is just amazing.

In the window type whatever you want fritz to say.

Check “random eye movements” and “random neck” movements select a tts and click activate.

Fritz speaks it with random expressions.

The tts is built in your windows computer.

Alternately if you have ultrasonic or ir sensor connected.

Check on of the box.

Enter the distance in cm to trigger fritz.

Maximum “100 cm”.

Press activate.

Now move in front of sensor and fritz jiggles!!.

I have installed fritz at my nearest makerspace attached a ultrasonic sensor at the sensor.

This option plays stuff written inside it if you want to play some good sequence there is another option.

Go to “options>distance trigger”.

Check trigger is enabled tick a sensor enter the trigger distance press "OK".

Now load a sequence.

Move in front of the sensor fritz plays the sequence.

There some options under “Audio” they are used for only add.ing mouth movements.

Alternately you can control it using keyboard or usb based joystick.

Configure them under “options>keyboard configuration” , “options>joystick configuration”.

If you press this button the current sequence is uploaded to fritz.

When you disconnect fritz from computer and power it alternately it does the expression without voice since it has no speaker.

This works as good Halloween idea.

Step 39:

That’s it.

Make one and enjoy.

Make different face plates such as “devils face” , “sharks face” or whatever you like.

Vote for me in make it move.

Future plans.

Avoid the use of robo realm.

Make an “AI” for it just like “Mycroft”.

Make an application that runs on all platforms.

Especially that runs on raspberry pi so that fritz is a stand alone module.

If you guys make any software changes please post it.
