el sapatero

OddBot is going to China, and he created several packs with robotics stuff and came up with a great creative challenge wich is to create a video with the keyword FUN. One of the extra points was to build something with paper, wood, and cheap materials, no techy thing here, the main purpose was to spend a great time creating a cool video to make others laugh. The other extra point was to build a PCB with non PCB materials like, paper, card, or any other thing, I’m so happy to know that paperduino was one of the inspiration to this competition.

“el sapatero” came with this great challenge in mind, and I wanted to build something really nonsense.. and started to play with stuff I have, and my wife appear with this silly boots made out of recycled card. This card boots(?) are used inside shoes to keep their original shape and I knew in that precise moment that I have to use them! :)


and the video for the challenge: http://letsmakerobots.com/node/8630



This was the first layout. I thought that I could build some kind of a walker… but I was wrong :D


This is a motor plug made with polymorph..


Polymorph plugged into the motor and with a plastic bit.. (can’t explain this in english)  lol


The polymorph structure was shaped in a way that gives fully support to the card boots.


This is the circuit, I wanted to try other non conventional PCB materials, and this time I tried with acrylic. I kinda like it.. its different…  but not an easy task..  I don’t know how many hours I spent with this..

It was a great disapointment when I saw that only the body spins.. and the boots remained still.

So I have to create another polymorph structure to give some traction to the entire system.


1st test drive

And the final result  :)

I used hotglue to reinforce the card. And this makes a cool accoustic sound coming from the boots  :)

And another quick testdrive :)

Zezinho, the poser and untitled circuits will be part of this exibition. See you there ;-)

Zezinho, the poser

This is Zezinho, a humanoid robot that likes to pose! :)

All the microservo supports where made with the amazing material Polymorph.

For now he is being controlled by 8 analog inputs, each input controls one microservo. In the future (as I hope) he will be controlled by a computer vision system where he will try copy real human poses in real time.
I’m still programming servo control functions and movements presets.


This is the analog inputs setup and a custom servo shield.

I’m using an Arduino Mega because I need more than 6 analog inputs that the regular Arduino boards have and I don’t have the time (or should I say patience) to digg around multiplexers.. I’m very lucky to have the support of InMotion.pt, they sent me the Arduino Mega for the first test drive. Thank you so much Filipe!! ;)

This robot will also be my final project for the course ‘O Som do Pensamento’. It will be an instalation where the user will be able to control his poses with physical controllers. I’ve made a controller box in acrylic and will post photos as soon as I have it with me.

Playing with movements and poses.

Testing movements and different servo speeds.

POP UP LX 09 - Vox Pop from popupcity on Vimeo.

POPUP is an Urban Art event realized by Hugo Israel, there will be installations, performances, sculptures, live music, illustrations and many other cool things. If you are near Lisbon you got to mark this spot on your agenda.

I am participating with Bruno Canas on two interactive video instalations. Will have more details soon ;)

Talkie Walkie

Lusorobotica.com and EmbeddedDreams.com made a challenge to build a robot only with one servo, and this was what I came up with.

I used the sound sensor I’ve done a few days ago and a little paper-boat + a servo and a box and this is the result :)

untitled circuits #1

“untitled circuits” is a series of experimental circuits based on paper and other materials.
I’m working on this project with Catarina Mota (openmaterials.org), and this will be our final project for the course “O Som do Pensamento”

#1 is a copper wire circuit on a paper support that generates sound in real time based on six LDR sensors.

The brain is a paperduino and we are using the Auduino from Tinker

PechaKucha Night Lisbon is next Wednesday (May 13) and I will give a 6 minutes presentation about robotic creations :)

It was my premiere talking to an audience, and I loved the feeling! I hope to be invited next time! :)

PAPERduino’s design

Arduino, Misc — Tags: , , , , , , , — GUI @ 5:08 pm

This is a fully functional version of the Arduino. We eliminated the PCB and use paper and cardboard as support and the result is.. the PAPERduino :D

This is the the first version of the layout design, next we will try more designs, and another materials. You just need to print the top and the bottom layout, and glue them to any kind of support you want. We hope that you start making your own boards. If you do, please share your photos with us, we would love to see them  ;)

There is no USB direct connection, so to program the paperduino you will need some kind of FTDI cable or adapter. One of this products will be fine:
FTDI cable from Adafruit Industries
FTDI adapter from Sparkfun

Download PDF

Components list:
1 x 7805 Voltage regulator
2 x LEDs (different colors)
2 x 560 Ohm resistors (between 220oHm and 1K)
1 x 10k Ohm resistor
2 x 100 uF capacitors
1x 16 MHz clock crystal
2 x 22 pF capacitors
1 x 0.01 uF capacitor
1 x button
1 x Atmel ATMega168
1 x socket 28 pin
Female and Male headers

Instructions:
Use a needle to puncture the holes for your components.

Don’t rush, place one component after another and do all the solder work carefully.

Follow the connection lines.

And this should be the final look of your paperduino connections.

PAPERduino for ALL

We had a great time building this electronic/paper pieces, and more are to come pretty soon .)
