Hello Kuka!

Posted on by Pete Prodoehl

Kuka KR 30

We recently got an email from a guy who runs a manufacturing company in the Milwaukee area. He said he had some extra equipment he was looking to donate, including a welder, and some wire, and some scrap steel, and oh yeah, a Kuka KR 30 Industrial Robot!!!

We said, sure, we’ll come and pick it up. ;)

To be fair, he did mention it “needs work” but we’ve already assembled a team of members interested in getting this thing up and running. We’re hoping that with the varied experience our members possess, from electronics to industrial controls to robotics and general hacking and tinkering, we’ll get this thing swinging around in no time.

And what will we do with it? Well, besides the silly suggestions of arm wresting, can crushing, and free high-fives at the next Art Jamboree, there’s been talk of multi-axis milling, 3D printing, and hey, just being awesome with a giant industrial robot arm!

Before we even think of firing it up we’ll be mounting it securely to the floor and building a safety cage. The last thing we want to do is reduce our membership due to an “accident” with the giant industrial robot arm!

Of course, until it’s up and running, it’s available for amusing photo opportunities. ;)

Baltimore Hackerspace Visit

Posted on by Pete Prodoehl


Baltimore Hackerspace

During a recent trip to Baltimore I got to visit Baltimore Hackerspace, take a quick tour, and talk to two of their members.

Our story actually starts back in 2011, when I was passing through Baltimore and tried to connect with Baltimore Node (another hackerspace in Baltimore) and when I mentioned on their mailing list I’d be passing through town, I got an invite to stop by Baltimore Hackerspace, which at the time was called “Harford Hackerspace” and was located in one of the member’s garage. Well, I never made it to either space last year, so I thought I’d try again this year… sadly, Baltimore Node does not currently have a space due to some issues with Load of Fun, the building they are located in. (Side note: I snapped a photo of Load of Fun back in 2009, before I was even a Milwaukee Makerspace member.)

Confused yet? Good! Anyway, Mike from Baltimore Hackerspace was kind enough to meet me there on a Wednesday afternoon for a tour. We talked about Power Wheels, Make Magazine, The Red Bull Challenge, how Baltimore Hackerspace operates, how Milwaukee Makerspace operates, and general making and hacking activities.

I snapped a few photos as well… enjoy!

Baltimore Hackerspace
Baltimore Hackerspace was not easy to find! It’s in an industrial unit (which looks a little like a storage unit) with no sign on the door. I think some signage is in their future, as it’ll really help new visitors find the place.

Power Wheels
Here’s their Power Wheels car. It looks unlike any other Power Wheels car I’ve seen. Like most Power Wheels cars, it occasionally starts on fire. :)

Telepresence Zen Garden
Here’s the “Telepresence Zen Garden” they built for the 2012 RedBull Creation Competition.

Robot Game
They had a robot game thingy, which was a little like Operation, but you had to guide a wand over the wire and not touch it, or the robot freaked out.

Recycle Robot
OK, this thing was impressive, and confusing. When I first saw this robot I assumed it was some commercially available unit, but it turned it was build using mostly scrap! Mark (the guy working on it) finds interesting pieces from children’s toys, household appliances, etc. and puts it all together. And, that weird thing to the right is indeed a walker, modified to assist the robot in walking, at least until it can walk on its own, without the help of a balancing mechanism. Great project!

Baltimore Hackerspace
There was also art to be found… I don’t know if this was done by a member, but it definitely added color to the space and let you know where you were. ;)

Space Invaders
Some Space Invaders were descending down the wall… I hope they fill the whole wall with them, it would definitely look cool.

Whiteboard
They had a small office for meetings, with a big table and chairs for hacking and what-not. The office also had this whiteboard, which may contain the secrets of the universe… or something.

MakerBot Thing-O-Matic
What’s a hackerspace without a 3D printer? Here’s their MakerBot Thing-O-Matic ready to melt some plastic.

Keyboard
Looks like they’ve also got some music fans (and maybe video nerds?) as members. I love the color bars!

Well, that concludes our tour of Baltimore Hackerspace… if you’re ever in Charm City, check ’em out!

Roomba-Bot!

Posted on by BenN

Today, I stopped in at the Makerspace with the plan to work on a small project for a Halloween party this Saturday.

The plan was to take a “Roomba” robot vacuum cleaner that I got for $1.00 at a rummage sale, and covert it into the robot base for a giant spider or some other scary creature that could wander around at a Halloween party.

I started pulling screws out of the bottom to figure out how to remove the brushes and vacuum blower. It took some tinkering to figure out what I could and couldn’t remove and not cause a fault. In the end, it didn’t look like I could remove the blower motor and still have the thing run, so I simply removed the fan blades from the blower.

By that time, I was now thinking about video cameras and how easy it would be to run a 1/4-20 bolt right through the plastic. A bolt and two nuts quickly made a camera mount.

In the other room were some ping-pong balls, and I had a black sharpie. A little hot glue and Roomba-cam has some personality.

Look for Roomba-cam running around the Milwaukee Makerspace and please treat Roomba-cam nice – he is watching you and WILL upload to YouTube!

Robotics @ UWM

Robot

We’ve got a number of robot builders at Milwaukee Makerspace, but we’re not the only robot-lovers in town… via Frankie’s blog, check out this video about Tom Consi and the robotics work he’s doing at UWM.

(We’ve seen some renewed interest in the Milwaukee Robotics Club recently, so we’ll probably start up regular meetings again in the next few months… that way everyone can show off what they’ve been working on.)

Android Blue or iOS Purple? Update on the OOMA project

Posted on by mmassie

The Object Of My Affection Lamp   I thought I would jump in and blog on my current progress at the Makerspace with a lamp called OOMA, or The Object Of My Affection. It’s a lamp that is shaped like a GPS Navigation pin that rotates to always points toward the one you love… as long as they allow you access to their Google Latitude account :). I am finalizing hardware designs and now moving into writing the software and how it talks to the Internet.

Initially I would have waived it off as using WiFi, or Ethernet, but work on another project (Marco) has illuminated several obstacles over multiple use cases (configuring Wi-Fi, closed networks, IP addresses); instead I think the approach will be to opt over USB (via Arduino Leonardo). I figure, if people will load up a coffee cup heater or foam missile launcher to USB, than there is no issue with port scarcity.

It’s not a lamp without light, and at some point OOMA will light up in either Android Blue, or iPhone Purple. Lighting the lamp will, however, have to relegated to a v.2 build, due to some complexity in the diffusion of light in such a cramped space. Additionally, I’d like to investigate EL panels to light it up.

Finally, I am coming up on the decision to be a DIY offering, or to design it to be marketable – do I build as a one off and just offer the blueprints to others or build an end-to-end consumer solution complete with potentially an NFC tag to tap and pair a user and their lamp.
