I´m participating in this workshop this week, to know more click the image:
AltLab, the new Lisbon hacklab
The new hacklab located in central Lisbon will start soon. To know more visit:

bigbro upgrade
This time I added the Solarbotics L298 Compact Driver Kit, the car is now much more powerfull and it is very cool to drive.
In the photo you can see a proto shield where I connected the Xbee, the motor and servo and the LEDS, than the L298N board and a 6v voltage regulator.
I added a small video with some “stunts” :)
(I´m using the G-Remote to drive this beast!) :D

Workshop Robótica Criativa – 1ª edição
Este fim de semana tive o prazer de dar a primeira edição de Workshops de Robótica Criativa no Porto no espaço Imerge e com o apoio fantástico da Inmotion.pt.
Farrusco 2.0
This is the new version of Farrusco, tomorrow we will build a bunch of them at the workshop, and you will be able to build your own very soon.. We are planning more future workshops! ;)
Say hello Farrusco!! :)
Ratazana drifting
I´ve been quite busy with the motor of this robot and I already started to have some of the results I wanted, but I still couldn´t find a stable setup, after a couple of drifts it starts to lose power as you can see by the end of the movie.
Besides this, I like the way it moves, and I can have some control when it´s drifting, it is now my anti-stress toy!!! :)
I have also made some major updates to the arduino circuit board. As you can see in the photo below, I finally have figured out how to upload code to a custom arduino board, (this post describes everything related to this), added capacitors to the L293D, added pins for the ladyada xbee adapter and also added pins for the sonar sensor.
To upload code, I have to add a switch button, to change the rx / tx wires from the xbee to the ftdi cable :)
Zoetrope, the premiere.
This is a short video of the premiere at TeCa of this great show. You can see more detais here.
Ratazana update
This post is a full description of all the building process, the main idea started with the ratbot, and then I found out that I could follow the same concept with a different approach :)

Ratazana
This is a ratbot derivated, faster, cooler, and with more fun! :)
I like pretty much the way it is going until now, but there are still things I want to do. Beside that, I can´t make it move straight in a line, it seems that it is not well balanced.
When finished, I will post details about the building process.
Robotic articulation prototype with Arduino
This is the result of a couple of tests with recently arrived microservos + Arduino programming + polymorph shaping technics + recently build G’Remote :-)
I don´t have any specific application in mind for this, the main purpose is to learn and test new concepts of mechatronic articulations, and to get used to polymoprh of what I became a big fan.
(sorry for the low light condition video, will make a better one)
