Animatronic Tail. by Pedrodeoro Nov 12, 2011

Featured Thing!

Description

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

This is a small test: http://www.youtube.com/watch?v=d1k9p1P4s8I

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 ;)

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.
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)?

<p>Very nice! Watching this closely.</p>

<p>Awesome work Pedro! Congrats! :-D</p>

<p>ty :)</p>

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

<p>What kind of power do you need?</p>

<p>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. </p>

<p>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).</p>

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

<p>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.</p>

<p>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.</p>

<p>Thanks for the comment ^ ^</p>

<p>a video with someone using it would be appreciated!! 8-)</p>
