This is a derivated design from the USB memory stick holder by thingiverse.com/jpcw

The main differences are: redesigned in openscad, parametric design and rounded edges

My wife wanted me to buy more Ikea hooks for the kitchen... As I am too lazy I decided to design the hook in openscad and print some of them!

As a bonus, I designed a parameterized Ikea hook so that the diameter, length, width and height can be easily changed

The Skymega is an electronic board for programming printbots. It is open source hardware, designed with the open source tools Kicad (we have named this kind of hardware as open source squared). It is based on the ATmega microcontrollers, so it is Arduino compatible.

This board has been specifically designed for building modular robots or mini mobile robots. Currently we are using it at Universidad Carlos III de Madrid for the following printbots:

* Miniskybot: thingiverse.com/thing:7989
* Repy1 1.1 modules: thingiverse.com/thing:13442
* F-track: thingiverse.com/thing:13298
* Orugator: thingiverse.com/thing:8559

Features:
* Small in size
* Easy to build by the students
* ON/OFF switch
* Arduino compatible
* Connection up to 8 servos
* I2C bus
* 1 Test button
* 2 Test led

Authors
* Juan Gonzalez-Gomez (Obijuan)
* Andrés Prieto-Moreno
* Itziar Lima
* Ricardo Gomez

This design is a mechanical module for building modular printbots (printable robots).
The main improvement of this design over v1.0 is that it has been migrated from Blender to Openscad. Therefore the drills and part's thickness are parametric.

The documentation has been done with Freecad. For more details just download and open the freecad files

Our goal is to build the longest modular snake robot ever! :-D

There are more information (in Spanish) about these modules in the following link:

This is the parameterized version of the servo wheel. The wheel diameter, height and o-rings parameters can be defined by the user. These are the type of wheels we are using for our printable robot projects. For example, the Miniskybot robot ( thingiverse.com/thing:7989 )

Currently the target servo is Futaba 3003.

The MiniSkybot is a new mobile robot aimed for educational purposes. It has three new important features: 3D-printable, fully open-source (mechanics + electronics) and designed exclusively with Open source tools (OpenScad, Freecad and Kicad)

This robotic platform allows the students not only to learn robot programming, but also to modify easily the chassis and create new custom parts. Being open source the robot can be freely modified, copied, and shared across the Internet. In addition, it is extremely cheap, being the cost almost exclusively determined by the cost of the servos, electronics and sensors.

This work is being done between three professors from the Robotics Lab at Carlos III University of Madrid and one part-time teacher at Universidad Autonoma the Madrid:

* Dr. Juan Gonzalez-Gomez (UC3M)
* Andres Prieto-Moreno (UAM)
* Dr. Alberto Valero (UC3M)
* Dr. Mohammed Abderrahim (UC3M)

Also, there are serveral engineering students involved.

The robot chassis has been design with Openscad. More information can be found on this link: iearobotics.com/wiki/index.php?title=Mini-Skybot_v1.0

The electronics consist of the open-source hardware Skycube board (http://www.iearobotics.com/wiki/index.php?title=Skycube), a small board with an PIC16F876A micro-controller designed with the open-source Kicad EDA tool.

The following things previously designed and uploaded to thingiverse have been used:

* Servo wheels: thingiverse.com/thing:4767
* Parameterized battery pack: thingiverse.com/thing:5079

The Chassis is an evolution of the proof of concept minimal chassis:

thingiverse.com/thing:4954

We want to thank to all our students who are testing and improving this robot. Special thanks to Olalla Bravo ( thingiverse.com/Olalla ) for the design of the Castor wheel.

This preliminary work will be presented soon at the 6th International Symposium on Autonomous Minirobots for Research and Edutainment ( amiresymposia.org/amire2011/ )

Yet another pair of glasses! It is a parameterized design with Openscad. The glasses consist of 7 parts joined by 5 3mm-abs-pins. So, they are fully printable and very easy to assemble.

If you glue red and cyan translucent paper, you have a wonderful 3D glasses!!

This design is derived from the parameterized Battery compartment: thingiverse.com/thing:5051 (By Guru). I have added a simple method for the electrical connections. The proof of concept was tested on this thing: thingiverse.com/thing:5070

NOW you can print your own fully-functional battery pack :-)

For every battery there are two embedded nuts in contact with the positive and negative poles. Two metal M3 bolts are inserted from the outside. They will contact with the poles. Now, you have a wonderful electrical access to the battery!!

I have tested with 2-AAA and 4-AAA battery packs. It worked like a charm :-)

In addition, I have added more parameters for generating the battery pack: the thickness of the bottom, front and rear, and side walls as well as the distance between two batteries.

Update: Jan/30/2011. Added the contribution of eaglepex ( thingiverse.com/eagleapex ). Now the batteries can also be in serial connection changing the ser parameter

This is a proof of concept. I have derived this object from the parameterized Battery compartment: thingiverse.com/thing:5051.

It is a Battery comparment for just 1 AAA battery. I have added two embedded nuts in contact with the positive and negative parts of the battery. From the outside, two metal screws are inserted. They will contact with the battery. Now, you have a wonderful electrical access to the battery!!

It works very well.

For the future, I am planning to add this feature to the original parameterized battery comparment.

Inspired by thing thingiverse.com/thing:5014 I have created a parametric flat star with OpenScad.

The parameters are:
N: Number of points
re: outer radius
ri: inner radius
h: Height

Three examples are provided: a 5-point, 6-point and 8-point stars

The MiniSkybot robot is an educational open robot. Its chassis is minimal: it consist only of two tricked servos joined by two U-pieces.

Now the robot is in an early stage of development. We are testing different minimal chassis.

(This video is intended for my students so I am talking in Spanish)

The pieces have been designed with OpenScad. All the virtual pieces have been assembled with Freecad

I have a coffee machine in my working room. Sometimes we forget to buy coffee stirrers... but now it is no problem. We can easily print them :-)

It has been designed with OpenScad

By the way, the coffee tastes better if you use your own printed coffee stirrer!

A wheel for building mobile robots. This wheel has been designed for the Futaba 3003 or compatible servo, but it can be change to other servos easily. It has been created with openscad.

For building mobile robots, the servos should be tricked so that they can turn freely.

We are using these wheels for our educational open-source Robot: Skybot

Articulated modules for building modular robots. It is the repraped version of the Y1 modules that I have created for my PhD.
iearobotics.com/personal/juan/doctorado/Modulos-Y1/modulos-y1.html
Version 1.0 is the first one. It works and it is 3D printable, but the design should be improved in order to obtain a better printing quality.

UPDATE: 09/Nov/2011
A new version has been released: thingiverse.com/thing:13442
