The REPY-2.0 is an open source mechanical module for researching Modular Robotics. It is designed to be printed on a Low-cost 3D printer, like a RepRap.

The main points taken into account when designed were:

* **Symmetry**. This way, the robot can move whatever the orientation of the module is.
* **Low-cost**. Modular robotics is usually a expensive area of research due to the fact that many small independent robots (modules) have to be built in order to build the main robot. Having a 3D printable design enables us to lower the cost of each module.
* **Customization**. With the same code it can be able to generate different modules according to the electronics and motors chosen. If our motor or board is not yet implemented we can do it easily by using the existent modules as examples, and with our new module the program will be able to generate a custom REPY-2.0 module.

This is Beta.

Beta is a robot controled by Arduino and a L298N. The communication is via Bluetooth as you can see in the video: youtube.com/watch?v=WrFWBjptyvQ&feature=g-upl

It has 8 servos: 4 to move the legs, and the other 4 to move the wheels; and 4 motors. To power the robot I have used 4 LiPos I had in my house, they are connected in series so I had to use 3 7805 to regulate voltage.

The servos I used for wheels are microservos, NO CONTINOUS ROTATION, imposible to control...

And for the legs, I used a few I already had. This ones I recommend to be more powerful than others.

The motors are geared and are this: dx.com/p/high-torque-80rpm-12v-dc-geared-motor-91628?item=6

The Bluetooth module: dx.com/p/bluetooth-board-module-4-pin-121326?item=2

And the L298N to control the dc motors: dx.com/p/l298n-stepper-motor-driver-controller-board-for-arduino-120542?item=4

The code for Arduino is the file "Codigo.ino"

I'm sorry for the lack of documentation I promise it will be more complete in the next version, Gamma Project.

This is V2, now it's parametrizable, you must to edit de config.h file, and put the measures of you want, you can modify length, height,width , and distance between servos. If you see any problem contact with me.

OOML stands for Object Oriented Mechanics Library. The OOML is a set of tools written in C++ that allow designers to create mechanical parts using the C++ language.

OOML applies the model of Object Oriented Programming to Mechanical Designs. Parts can be inherited from others. A part can join together other existing parts, and so forth.

OOML is Open Source, you can use it, modify it, share it.

The D-Track is a versatile, printable robot designed for both teleoperation and autonomous behaviour. Its unique design, inspired by the 4-Track by Jon Goitia [1], preserves all the advantages of wheel and track-based motion while overcoming some of its disadvantages: the articulated tracks allow the robot to handle difficult surfaces and overcome obstacles that would limit the motion of simpler wheeled vehicles.

This project is one of many that have been initiated at the University because of the innovation that has led printers Thing-O-Matic, by Department of Systems Engineering and Automation, in the field of robotics. Also it has the objective to test the viability of low cost printable robotics.

The objective is to design a vehicle using as main tool the department’s 3D printers. To this end, agreed to a free-school course taught at the University Carlos III of Madrid where instructing you the tools, both software and hardware, which is needed to make proper use of printers, design and control robots.

This caused a large number of projects related to printable robots. The novelty of this proyect with respect to others is the use of motors DC, as so far all printable robots used servos for both, its movement and its displacement. Moreover, most of them for the actions mentioned and making use of the power units have used differential control, while in this is used directional control, the same that used by commercial vehicles.

To control it will use a gamepad, that is to say, a console controller, connected to the computer. With it, anyone can handle the robot intuitively even without any knowledge of robotics. This is due to the great developments that have these controls with the new generation of consoles, which make it a familiar instrument and easy to use.

The vehicle used by Bluetooth wireless communication, allowing freer movement of up to 9 meters away to the point of control (computer) through the removal of the cables.

The intermediary element receive gamepad orders sent by Bluetooth is the Arduino Leonardo, OpenSource hardware available to everyone, which will process the received data and send the necessary signals to move or react the vehicle.

This is the low-cost prototype of a robotic arm with 6 DOF, 3D printers manufactured and designed using free software (OpenScad, Inksape..).

The "AT-AS" (All Terrain - Anita Scout) is a printable quadruped robot.

The AT-AS is a project of an efficient robot, as it has achieved a useful and complete walking robot base using few technical and economic resources. In addition, it is a flexible robot project since its design is open to many development possibilities in future works such as the transformation of the quadruped model to a hexapod model, easy modification of leg and modular structure design, the possibility of adding sensors to improve control or communication with other robots using wireless networks via Xbee modules.


I used two parts of the "Versatile Servo Bracket System" created by bryanandaimee:
thingiverse.com/thing:5784
But the rest of parts has been designed by my own, using OpenSCAD and C++ OOML (Oriented-Object Mechanical Library): iearobotics.com/oomlwiki/doku.php?id=start


For the AT-AS implementation, I used:

- 1x Arduino Mega 2560.
- 8x Servo Futaba S3003.
- 1x Lipo Battery (2S, 7,4V).
- 1x UBEC (5V).
- Remote control through a Gamepad connected to a PC.
- Wireless communication through Bluetooth or XBee modules.

But this robot accepts others microcontrollers, servos (with similar dimensions) and others components for its control. Use the one you prefer!

EVOLUTION:
Quadruped Robot --> Hexapod Robot
----------------------------------
The part called: "hip_evolution_hexapod" is only for the transformation of the quadruped model to a hexapod model. Using this part, just need to print another two legs! :)

Mars Rover. Here is a new Mars Rover design created from OOML (Oriented-Object Mechanical Library). A very easy way to develop prototypes!

This design uses a double printed bearing and two springs. Also, it is ready to be controlled by an Arduino UNO or a SkyMega microcontroller, with a place for the battery. This Mars Rover uses Futaba S3003 servos and a Bluetooth module. All these components are important because of the shape of the parts; however, you can modify it and buy your own prototype. With OOML tool modification of design is very simple!

Oriented-Object Mechanical Library is a new mechanical design tool, based on C++, which makes it easier for users to share designs, besides acquiring the power of this language.

Whether you know C++ programming or not, I encourage you to test it. Take a look at iearobotics.com/oomlwiki/doku.php?id=start

I attach the OOML, OpenSCAD and STL files, besides the Autocad planes. The OpenSCAD files are results of compiling the OOML file, so these codes are uncommented.

You can see a video of the prototype in the next link: youtube.com/watch?v=hCLwgrm9mkM

Robotic Arm created with a 3D printer by Alejandro Aguilar Romero. It consists of several modules connected with servos Futaba S3003.

You can see the arm working in the following videos:
- youtube.com/watch?v=sbEiRr2WQlk
- youtube.com/watch?v=sUzbNl0DV4Y

Comments:

1- I customized BasePesas.stl to use 2 weights I had, to make it heavy enough not to fall every time the arm moved. If you can't find anything similar to the weights, you'll just have to adjust this part in order to make 1 servo fit and hold the arm properly.

2- I only use 1 servo for each module, leaving the second one empty just to let the whole part rotate. At the moment, I don't think there's need to use 2 servos for each module and I decided to remove it because I'm not sure enough about the overheat of both servos if they try to reach the same position at the same time. In any case, it should be fine if you want to have 2 servos per module.

3- I used glue to make the gripper to servo safer (MunecaPuente to BasePinza). For the rest of the arm, I used ordinary screws. These could be printed as well.

4- I've already printed and assembled the whole project, but I'm still testing its functionality. Photos will be uploaded soon.

This improvement of the Wade´s Geared Extruder provites more continuity of the plastic filament to the hot-end.

This is just the same robot as thingiverse.com/thing:18264

But I've created a new part: spacers. Their objective is to support the Arduino board, allowing to place a 9V battery below it. Its advantage is that the battery is just above the wheels, so the grip is slightly increased :)

The Arduino code which makes it able to navigate inside a corridor is also attached.

We had add an aditional piece for the scout to hold on another servo motor with an ultrasonic sensor. The sensor data are sends to a pc by bluetooth to be processed and displayed.

Today I would like to show you a printable Rocker Blotter. I suppose people who love the "calligraphy world" will know what it is, and how useful it may become. For people who don't know about it, a rocker blotter is an antique tool, used to dry the ink which doesn't dry so fast. With this tool, you avoid to damage your work letting rests of ink all around the paper.

I made the code in C++, using the new OOML library (http://www.thingiverse.com/thing:17761 iearobotics.com/oomlwiki). So, If you want to change some of the parameters (measures) or work with this code to made some derivated or new desings, you should download this libray. Afterwards, you only have to open de project and modify the independent parameters (in RockerBlotter.cpp).

However, I also add too the OpenScad generated code; although I think it isn't very intuitive to change. (I really advise you to work with OOML).

This is a derivative from Protobot by Alberto Valero:
thingiverse.com/thing:18264

We have used the base structure and the wheels. We have added one plug and play structure to hold the US sensors and we are developing another plug and play to put PCB board with sensors CNY70 in order to detect lines in the ground and make the robot lines follower.


In this model, we have used:

1x ARDUINO UNO
1x BT ARDUINO MODULE
2x FUTABA3003
2x US sonar (http://www.seeedstudio.com/wiki/index.php?title=Ultra_Sonic_range_measurement_module)
1x Connection board
2x 9V power batteries
22x screw (3mm)

This is a sensor plugin for the ProtoBot Robot.

The ProtoBot ( thingiverse.com/thing:18264 ) is a prototyping low cost robot. Designed for Arduino UNO and Futaba S3003 servo it can be adapted easily to other boards. The ProtoBot has been entirely developed in C++ OOML.

The sensor plugin can be attached to the chassis of the robot without requiring any modification. The plugin is designed to hold two Seed US Sensors and one Sharp IR Sensor.

All plugins for the ProtoBot are being published with the ProtoBot tag: thingiverse.com/tag:PROTOBOT.

A video of the ProtoBot model can be found in: youtube.com/watch?v=TXOgm4QIgj0

Well, this is an Open SCAD parametric design for a led display, you can print the display with the numbers of columns and rows you want. =)

I built this small prototype to test several concepts: the tracks made from O-rings, a simple robotic claw, and wireless communications with Arduino.

This thing uses:
My robotic claw thingiverse.com/thing:18339
Some parts from my previous designs thingiverse.com/thing:13298
Obijuan's Skymega board thingiverse.com/thing:14197 and battery pack thingiverse.com/thing:5079

See it move at: youtu.be/SQqVQEaMtno

UPDATE 3/8/2012: The part "front.stl" did not print correctly due to some dangling polygons. I have now replaced it with the correct file!

UPDATE 3/13/2012: Uploaded a folder with the scad files. Not very tidy though...

That's a new design of servo wheel & a new wheel model available to the Protobot:

thingiverse.com/thing:18264#

Well, u know... is only a non-comercial replica of the Davy Jones Key, stl and scad files. =)

This is a small robotic claw designed to pick up a can of Red Bull Shot. It was really an exercise to make the simplest possible mechanism that would get the job done, with the least number of parts and as small as possible. It works quite well, even though the pincers could do with a little bit more friction for a better grip (add rubber bands?)

The ProtoBot is a basic prototyping minimum robot developed in OOML (v2.0) (Object Oriented Mechanics Library) iearobotics.com/oomlwiki

The robot was inspired by:

MiniSkyBot: thingiverse.com/thing:7989
Scout Robot: thingiverse.com/thing:13042

It is designed to mount an Arduino UNO and a protoboard, so the users can add all the electronics and sensors they may want.

The body takes less than 2 hours to be printed on a MakerBot TOM.
The wheels included in the ProtoBOT are derived from the MiniSkybot wheels (http://www.thingiverse.com/thing:7989) designed by ObiJuan (http://www.thingiverse.com/obijuan)

A list of other available wheels is:

thingiverse.com/thing:9071
thingiverse.com/thing:9204
thingiverse.com/thing:18377


As a castor wheel it uses a Ball Wheel Holder, inspired by the Scout Robot (http://www.thingiverse.com/thing:13042). The diameter of the wheel is typical in Spain (16mm aprox). For different diameters you can easily change the cpp code of the Part.
