The motoruino is so easy to setup, just plug the motors, sensors, upload code and your bot is ready to go.
I added a big capacitor (4700uF) on the PCB power connections as I had the Motoruino resetting randomly when a motor started (OddBot explains everything here)
This is a quick test drive with the demannu (unnamed bot).

It´s since I started with robotics, that I felt the need of having a board where I could directly plug-in my motors, servos, sensors and all the stuff without having to purchase extra shields, or building pcb’s and soldering and troubleshooting and hours and hours of hard labour.. so, I decided to start designing a new Arduino board. When I mention design, I didn’t actualy design the board in cad software, this amazing task was accomplished by my friend David Palma.
We talked a lot about usability, electronics and how to introduce robotics to newbies, and this is the first batch we ordered. We are working on a new batch with more layout improvements.
Main key words:
– easy to use, understand, play with;
– must be a plug-and-roll board;
– to be suitable with shields, and with regular Arduino Diecimilla/Duemillanove boards;
– the usage of the H-Bridge is open, i.e., there aren’t any Arduino output pins assigned, the user can use the bridge the way he/she wants;
– motors supply and PWM pins might be used with external voltage or regulated 5 volts
– motors have 3 different connectors, screws terminals, male headers, JST connectors
– two possible FTDI/USB connections available:
1. USB / TTL convertor, there are some choices on the market for this one, you can have it in the form of a cable, or in the form of a small pcb
2. USB adaptor with the FTDI chip embedded
The board fully assembled is pretty neat and clean.
Next batch will be in black :)
I’ve found this two rc vehicles on a junk, they are in a very bad condition. The big one has the DC motor burned out, I will try to replace it.. brushless motor maybe.
They both have two different gear mode (hi and low speed), I am wishing to try it out.
This is the dead motor..
The small car doesn’t have the rear suspension, I could try to rebuild it but I wanted to try something different with this one. I want to go for a chopper tricycle style :D
It’s a bit weirdo, and I’m very unsure if this will work, but I will give it a try.. If it fails, I want to try with one of the original wheels on the front, the reason I didn’t try is because I don’t have a way to hold the front wheel right now, I must look on a hardware store for a strong wire and it is 2 AM right now.
Is much stylish this way, definitely, this way it would be an all terrain tricycle!! :D

Audiência Zero will hold a multidisciplinary artist residency with its three laboratories (altlab, LCD, xDA) in O Espaço do Tempo (Montemor-o-Novo) in the period between 01 and 07 March and 14 and 23 June. The projects produced will be shown between 12 and 25 July. The residence is primarily intended for the current members of this laboratories, but participation of external elements is accepted where proposals are consistent and interesting. More information and registration at the end of this page …
Those interested in residence should express their interest and enroll as soon as possible (end of page) to secure a place. The organization will contact you to follow up the application.
When asked by the organization participants must indicate whether they have a project in mind to develop or an activity to propose. The clearer the projects and activities, as well as the roles played by each element of a team, the greater the likelihood of the activity or project to be integrated into the residence.
Vacancies in the residence are limited to 15, with the right accommodation and a daily meal. If there are more than 15 participants, the organization we’ll have to choose the most interesting projects addressing the following selection criteria: creativity, technologies involved, feasibility and time.
After the registration period, applications will be assessed by the organizers and established resident artists. We will begin the discussion of projects / activities and define the residency theme.

Two more infrared sensors were added on the front, this way he’s more sensitive to the environment. Video is on the go..
You can see more details about the construction process on this post.
Updated version here.
Everytime I see PAPERduino’s being featured in blogs, websites, and other people projects I feel joy! This time I have the surprise of looking at the Concurrency website, the new multithread language for Arduino, and I see the PAPERduino giving this guys the ideia of taking it to a higher level, I present you the Cardboarduino: “The Cardboarduino is physically larger than the PAPERduino, and includes space for a 9V battery clip.”
The bottom shows all of the pins that need to be soldered together with wire.
It’s been quite a while without building robots… errr.. creatures..
anyhow I’m releasing this new creature, wich is still a work in progress.. and since I can’t think on a name for it, I will call it demannU, witch is “unnamed” backwards… sounds like ‘demon’, and for the sake of insanity, it looks like a little demon..
the wheels where designed by Catarina Mota, and if you go to thingiverse, you can download the source code, and print your own wheels if you have access to a 3D printer
pololu mini gears, i strongly advice this motors, very powerfull and fast
this bits will be the motors supports
and after some dremel work they look nice and ready to hold the motors
the chassis, this time I wanted to try wood, it’s quite good to work and to do fast prototyping
et voilá
It isn’t finished yet, but I wanted to share with you :) will add more sensors and more cool stuff as soon as I have time

The architect Nuno Monteiro invited me to enter a contest to present an exposition concept for the “Trienal de Arquitectura de Lisboa”, and this was our proposal. My work consisted in finding a way to vizualize the exposition space and its different areas, and to achieve this nothing better than an aeral 3D perspective:
Another view of the exposition:
Codebits was an amazing event! I totally wish to be there next year!
This was me during the Creative Robotics talk, you can see the video below. I was a bit nervous for no apparent reason, just hope to be more relaxed next time.
Mitch Altman’s bench:
During three days people could learn how to solder and build cool stuff, TV-B-Gone’s, Brain Machine’s, Boarduino’s, POV’s and a lot more.
Mitch Altman’s Talk about HackerSpaces, a must see:
AltLab’s makerbot was there too, and there where lots of cool things being printed all the time

I was invited to assist Mitch Altman during codebits. I believe it is going to be an amazing experience. :)
I will also talk about Creative Robotics on Friday at 2PM.
Filipe Valpereiro from InMotion.pt will talk about Arduino, and Rui Madeira will talk about OpenFrameworks.
Hope to see you there ;)
