Promulgate

promulgate_icon

Promulgate is an Arduino library with a very simple protocol to allow communication from Arduino to other devices.

Check out the video to see it in action!

The library was designed so that you can add Promulgate quickly to a project. It is very simple to parse and transmit messages.

To get started, go to RoboBrrd.com/promulgate. There is an example and boilerplate code for Arduino and Processing.

The code is available in this repository.

If something breaks in the library or could be improved, feel free to let us know. We’re constantly learning, so if it’s wrong, we might not have even realised this.

You can also see our post about our two Promulgate + iOS demos.


This work was supported by our great Robo-Patrons. Consider backing us on Patreon to help us make more projects!

Gear Art vs RoboBrrd Banana Transporter

Check out this cool gear artwork piece that we made — or as the RoboBrrds called it, a magical banana transporter!

Watch the video for the entire story:

How this project came about was we wanted to create something for our backers on Patreon. Our first ideas were rather inanimate. We needed something that could move and look interesting. The gear art is the result of this thought.

The .stl files are available for you to download and print one yourself. You can find it on our Open Source Hardware page.

We also captured some ‘making-of’ timelapse footage and compiled it into a video:

One of the aspects of the design that surprised us was that we couldn’t find a formula for aligning the gears via experimentation. All of them required a ‘fudge factor’ in either their positioning or diameter. We got around this by just focussing on making each gear mesh with the one previous, and then finally working on the final gear.

Here are some of our favourite photos of the project:

We are experimenting with story-telling with our robots. We want there to be an entire world of these robots, where they are always plotting, building, and generally goofing around. Hopefully it makes the video more interesting and enjoyable overall.

One of the areas that could improve would be the speech bubbles. If they are added later in the video editing process, we could focus on animating the robots rather than moving the bubbles in and out. We have to learn different video editing software for this, it might take a bit of time.

It’s fun to get lost in Planet Zimpopodu with the robots. Let us know what you think!

Thanks for watching and sharing our new video. We’re already excited for the next ones! :)

New Paint

You might have noticed, RoboBrrd.com has a new coat of paint!

new_robobrrd_site

This is version 2 of the design of our website. We took away much of the distractions and bloat on the front page, so it loads quicker and with less data now.

There is a lot more room for new robots. This is great because we want to make some more characters. ;)

Also, we have come up with the name of the planet that the robots reside on: Zimpopodu!

You will find some pages around the site that are a mix between v1 and v2. The content is the same. New pages will use the updated v2 template.

Let us know if you find anything broken or can be improved. Hope you enjoy the new look!

Timelapse Video

 

Here is a short video of the making of the boards in gEDA! Time goes by so quickly on timelapse mode…


 
Watch on YouTube

 

 

New Tutorial

 

We are including 3D printed enclosure ‘sleds’ with each of the boards. It would be very tedious to design these by hand, but there is a way you can export the pcb from gEDA into Inventor. We thought we would share this with you!

Open Source Hardware!

 

The gEDA pcb files, as well as the Inventor enclosure files are open source!

Experimental Dual-Extrusion Buddy 4000 Face

Happy 2014 everyone!

To start off the new year, here was a small and fun experiment we did lately. Damian G all the way from Sweden has a Makerbot 2X, and he wanted to try printing out pieces for Buddy 4000 in dual-extrusion. We worked on the files and sent them to each other via email. After a few tries, there was a good result!

Erin_V2_plate

The layers of the accents didn’t have to be embedded very far into the other layers. They also had to extend a few layers higher than the base print, otherwise the filament would get mushed together. It seems quite tricky to align two extruders.

Thanks to Damian for having the patience to try this out with us! Pretty fun!

Wyolum Article

A while back when we wanted to start developing RoboBrrd into more of a kit version, we received a grant from Wyolum. There’s a great article featuring Justin Shaw describing more about Wyolum, Open Source Hardware, and STEM.

RoboBrrd WyoLum

One of our favourite parts of the article:

Our stated mission is to “promote Open Hardware.” Many small projects are out there that need only a small financial nudge to succeed. The grants are too small to pay anyone’s salary, but are large enough to buy hardware, or print circuit boards, or to purchase tools. The grant winners actually end up making the much larger investment of time. While not limited to students, all of the grant winners so far have been college or graduate students. The Open Hardware vocabulary grows with each successful design, so we all benefit from their success.
