Hello everyone! First of all, I wanted to share with you some notes regarding the latest updates made in the website:
Next, here is "Micro", the latest member of the family! It is a Printrbot Jr:
Micro is performing very well. The main difference with the other printers is that it is possible to have it the desk, since it is so compact and quiet. It also has quite a small printing volume (~14x11x8.3cm), but this is not a problem as all and the prints have a good quality. It is also the cheapest printer I've ever seen. Definetely recommended. More pictures of Micro can be found in this album.
This new little printer has been the main reason to stop using the Printrbot "Lucy", which now needs some fixes (since it has been disconnected since Summer).
Finally, you may have seen the printable caterpillar tracks:
They are based on Caterpillator by Olalla, and on the Stretchy Bracelet and Moon Rover by emmett. Single-printed tracks have proved to work very well. I have used PLA from RepRapWorld, which is flexible enough for this purpose. Here you can see a demo video of the first version.
Thanks to the power of the community, a few days later after they were published, Jason Welsh released his own (and improved) derivative: the Arduino Book Case (Tank Tracks Mod).
The main limitation of the *SkyBot family of printbots has been that their wheels behave poorly in rough terrain. Since this new design doesn't require a complex assembly for the tracks, it is easier to get printbots replicated. This concept will be the base of our next robot design for testing swarm algorithms at the GNB-UAM.
Of course, I will appreciate and answer any question you post in the comments (personally I prefer this method rather than email, also remember you can write in english or in spanish).
