Featured Thing!

Description

This is a fully printable mobile robot I designed and built last year. However, it wasn't very useful until Julián Marín Mato added some electronics and wrote some code to control it with a gamepad. Now that we can say it's finally 100% functional, we'd love you to play around with one too!

To see it in action, check out this video: http://www.youtube.com/watch?v=54MXA22bOmQ

There are, of course, things to be improved: using more powerful servos, strengthening some parts, adding wireless comms, etc. All that will come in the (near?) future.

Nice robot! very extravagant, I like it! I had it in my hands when I was in Madrid and I couldn't figure out how this robot can move! really smart!

Instructions

All you need to do is print out the parts and assemble! The axles are M6 bolts (with their ends cut off, because they were too long). To assemble the individual tracks, take a look at http://www.thingiverse.com/thing:7640. I hope the rest is (more or less) obvious. If anyone is having trouble, let me know and I'll post more detailed building instructions.

Note: The files frontframe and backframe can be printed as they are for 2 tracks, but for the other 2 you must mirror them! (the robot is symmetrical)

Note2: The servos that operate the tracks must be modified for continuous rotation!

I very interesting concept but could not view the video??

Would like to see it in action... =-O

That's strange... everyone seems to be able to watch it on youtube! Try searching directly for "4Track - robot".
I noticed that you are using rubber bands for tracks. This site has a few ideas on how to make several different types of track. It might help you get more traction.

Thanks! Those tracks are really amazing, the only problem is that they seem to be quite big and heavy, so I doubt they would work well on a smaller robots like this one.
The awesomeness of this cannot be expressed with words...
all the infor on the board can be found here: iearobotics.com/wiki/index.php?title=SkyMega
Congratulations!!! Great works!!!!! :-D

The source file works, but there is a problem with the space in the file name. It is better to rename it to "openscad_files". I also thing is better to upload it in zip format. It is more convenient for the window users.
I re-uploaded it with your suggestions!
and the space... :P

Nooo! I swear the file has an underscore, not a space, but for some reason it doesn't show up on the file list. :(
¡Buenísimo! ¡Muy buen trabajo!
Una pregunta: ¿Usáis Arduino para controlar los servos?
---
Cool! Good work!
Question: Are you using Arduino to control the servos?
Kepler - in reply to Guest
The board that we are using is called the Skymega, and was designed by Obijuan. It is basically an atmega 328 microprocessor (same as the arduino) with all the necessary components for serial communication and pins broken out for 8 servos. I think Obijuan should upload the design to thingiverse!
Estoy contigo; si Obijuan sube la info de la Skymega (aqu
í o en iearobotics.com), sería genial.
¿Habéis considerado hacer una versión autónoma controlada por un mando de PS3 Bluetooth? :)
---
I'm with you; if Obijuan uploads the Skymega info (here or to iearobotics.com), it will be great.
Did you consider making a autonomus ver
sion controled by a PS3 Bluetooth pad? :)
Cool robot :)

The tgz file appears to be corrupted , or not the right file.
*DONT_KNOW*
it works fine for me. I have already printed one :)
This is a PrintBot!!!
could you also upload the source code of the micro and the software for tele-operating it??
