Description by the Robjects designer, Jaidyn Edwards:

Robjects simply mean 'Robotics objects'. You can 3D print various connectors and blocks that interlock with each other to make bigger and more complex designs than what hot glue and foam board is capable of.

Prototyping robot designs can often be frustrating. Whilst I do love hot glue and double sided foam tape, they can leave a nasty residue on your parts.
To solve this I wanted to come up with a system that allowed me to turn my robotics components (Servos, Arduino etc.) into a modular system that would allow me to quickly prototype designs, but also make those designs permanent.

Robjects is what I came up with.
Through a series of male and female dovetails your parts will simply slide together. This way you can layout your whole robot design, be it a 6WD beast, or a 2WD obstacle avoider. Once you are happy with your design M3 nuts can be places in the male dovetail nut traps. M3X20 socket head screws can then go through the female dovetail into the male dovetails nut trap.
Robjects are still very much a work in progress.

There are a lot more blocks that need to be modelled and I am still considering different connector options. I am putting them up on Thingiverse now because I need your help. I've only just made a 3D printer of my own and I don't know how the system will work on others, my tolerances may be wrong, the numbers could be way out of line. So far all my pieces fit perfectly and the set screws hold them together like a rock.

Motorola (owned by Google) and 3D Systems partner up on modular 3d printed Ara smartphone. Idea behind it that you will able to make a custom smartphone with exchangeable and upgradeable modules.



Here is a video on why it is not going to work:

From 3d Systems page:

As part of this agreement, 3D Systems plans to substantially expand its multi-material printing capabilities including conductive and functional materials. The company also plans to combine additive and subtractive manufacturing methods, and deliver an integrated high-speed production platform. Pending successful completion of the development phase, 3D Systems is expected to manufacture 3D-printed Ara smartphone enclosures and modules as Motorola’s exclusive fulfillment partner.
Motorola and 3D Systems, the inventors of the cell phone and 3D printer, respectively, have previously partnered on the MAKEwithMOTO tour, a series of make-a-thons at the nation’s top engineering and design schools aimed at exploiting the power of open, hackable smartphone hardware and 3D printing to begin seeding an open hardware ecosystem.

Interesting movement modules that can be used in several configurations. I guess they could be used with 3d printers also ...

Video claims some sort of patent but that may be questionable ...
