This is a prototype animatronic tail, OpenScan designed 3D printed on a 3D printer and controlled by Arduino.

This is a small test:

I attached in a text document the code that use to control the servo with arduino.

Uses the number of vertebrae that want, i use 10 plus the final. I put a rubber cord in the side holes to keep the tail as, in the other holes, i put a normal string attached to the wheel. And so that the rope does not slip from the wheel put some small aluminum rings.

I hope you like ;)

Could you show me the servo to wheel connection? A block diagram would be awesome showing the arm. buckle, embrace and wheel.

What if you tossed the servo, put straps on your knees/thighs and attatched the cables to the straps, then it would move as you walk (no batteries needed)?

Yes, you can use for that. The design has a "buckle" for attaching to belt.

Arduino needs a 12 V battery, you can carry in your pocket.

Very nice! Watching this closely.

Awesome work Pedro! Congrats! :-D

What do you think is the maximum length it can scale to regarding force and friction?

What kind of power do you need?

Hi, I have not done more tests yet but, i can tell you is I use a Futaba Servo S3003, working at 5V with 3,2 Kg of torque. With this power approximately can be pulled a 17% of the string maximun lenght.

To improve this value, we should make lighter vertebrae, use flexible wire instead of string (there are much friction now), and of course increase the power. And i want reduce the wheel radio (I have do more tests).

This is the first prototype, but with a desing upgrade, could catch objects, this
idea it may be interesting.

I was watching the video, and you seem to have a problem between the 2nd and 3rd vertebra (counting from the disc). They keep moving apart, and then spring back.

Yes but it can be solved by putting more rubber rope gures between these vertebrae. Also the tail is designed to put a latex skin over, giving it more body.

Thanks for the comment ^ ^

a video with someone using it would be appreciated!! 8-)
