Open-Source Robotic Arm Now Within Reach

For anyone looking for a capable robotic arm for automation of an industrial process, education, or just a giant helping hand for a really big soldering project, most options available can easily break the bank. [Mads Hobye] and the rest of the folks at FabLab RUC have tackled this problem, and have come up with a very capable, inexpensive, and open-source industrial arm robot that can easily be made by anyone.

The robot itself is Arduino-based and has the option to attach any end effector that might be needed for a wide range of processes. The schematics for all of the parts are available on the project site along with all of the Arduino source code. [Mads Hobye] notes that they made this robot during a three-day sprint, so it shouldn’t take very long to get your own up and running. There’s even a virtual robot that can be downloaded and used with the regular robot code, which can be used for testing or for simply getting the feel for the robot without having to build it.

This is a great project, and since it’s open source it will be great for students, small businesses, and hobbyists alike. The option to attach any end effector is also a perk, and we might suggest trying out [Yale]’s tendon-driven robotic hand. Check after the break for a video of this awesome robot in action.

Listening tests reveal significant sound quality differences between various digital music storage technologies. Finally the audiophile press is tackling the important questions. This listening test looks at the difference between two four-bay NAS boxes, with one making the piano on Scherzo and Trio from Penguin Café Orchestra’s Union Cafe sound more Steinway-like, while another NAS makes it sound more like a Bosendörfer. Yes, your choice of digital storage medium can change the timbre of a piano. Another gem: “Additionally, the two units also had different processor architectures, which might also affect perceived audible differences.” There must be a corollary to Poe’s Law when it comes to audiophiles…

[10p6] has begun a project that can play every old Atari cartridge. Right now it’s just a few bits of plastic that fits every non-Jaguar Atari cartridge, but it’s a start.

The Android IMSI-Catcher Detector. You’ve heard about Stingrays, devices used by law enforcement that are basically fake cell towers. These Stingrays downgrade or disable the encryption present in all cellphones, allowing anyone, with or without a warrant, to listen in on any cell phone conversation. Now there’s an effort to detect these Stingrays. It’s open source, and they’re looking for volunteers.

[Rob] sent in something that’s the perfect application of projection mapping. It’s called Face Hacking, and it’s pretty much just a motion capture systems, a few projectors, a whole lot of CG work, and just a tiny bit of dubstep. It look cool, but we’re wondering what the applications would be. Theatre or some sort of performance art is the best I can come up with.

A while ago, [4ndreas] saw a 3D printed industrial robot arm. He contacted the guy for the files, but nothing came of that. [4ndreas] did what anyone should do – made his own 3D printable industrial robot arm. The main motors are NEMA 17, and printing this will take a long time. Still, it looks really, really cool.

Step Into The Box

Take three industrial robots, two 4’ x 8’ canvases, and several powerful video projectors. Depending on who is doing the robot programming you may end up with a lot of broken glass and splinters, or you may end up with The Box. The latest video released by the creators project, The Box features industrial robots and projection mapping. We recently featured Disarm from the same channel.

The Box is one of those cases of taking multiple existing technologies and putting them together with breathtaking results. We can’t help but think of the possibilities of systems such as CastAR while watching the video. The robots move two large canvases while projectors display a series of 3D images on them. A third robot moves the camera.

In the behind the scenes video, the creators revealed that the robots are programmed using a Maya plugin. The plugin allowed them to synchronize the robot’s movements along with the animation. The entire video is a complex choreographed dance – even the position of the actor was pre-programmed into Maya.
