Print Your Own Robot: Part 9

This will be an update on the things I’ve learned molding quadrupeds over the last couple of months and some previews of the new robots I’ll be experimenting with in the next few weeks. To start, I’ve had the chance to run a gaggle of design experiments ranging from small changes to the particular silicone I’ve been casting, to more radical changes to how the whole plionics manufacturing process comes together.

First to Blog

This is a response, more of a high five, to Zach Hoeken’s post up on MAKE: “First to File? Nah, First to Blog!” Basically his post was a series of ideas that have been hanging around in his notebooks, possibly eligible for patents, that he would rather see out there and made in the world than locked away between the pages of a personal sketchpad forever or exploited to the chagrin of mankind by some unruly technological entity, wrapped up in complex patent labyrinths, and never put to a more just use than in sole product from a sole company (see 3d Systems vs the Form 1, Patent Busting3d printing patent challenges, etc). Even worse is the possibility of an idea getting patented and never implemented, only used as a club to hit innovators over the wallet (see Intellectual Ventures). I’m in favor of this. Truth be told I’m pretty aggressively anti patent, which is why all of my recent robotics projects have been released into the open source. Although I realize there’s a difficult road ahead, finding ways to keep funding innovation and novel IP in the world patent abolitionists have been gunning for, I believe open access to information and the network effects it generates far far and away outweigh the small innovation boost you get from researchers confident they’ll be the only people able to profit from the particular idea they’re developing.

Print Your Own Robot: Part 8

Visit my soft robot Flickr collection for some detailed documentation and more info on the methods behind this latest robot.

Quadrupeds. I’ve been dreaming about quadrupeds. I’ve been hunting for challenges to test my methods and improve the engineering on the whole “print and cast a soft robot” thing (I really need to come up with a name for this… “Borgatronics?”). I started with tentacles because they were easy to design, easy to test, and symmetrical.

Print Your Own Robot: Part 7

I am now the happy owner of a fully functional robotic tentacle. I’m pleased. After a few iterations, some hair pulling, and some welcome help from programmer, hacker, and generally pleasant person: TQ, the Trefoil Tentacle is now waving around in disconcerting glory. You can find a whole set of high res images of it here.

If you’re craving an animated GIF of a tentacle wiggling about, this here’s your image.

Ceramic Knuckles

Ceramic 3d printing exists. Every so often I’m reminded that I live in the future and that it is AWESOME. It needs some work, but egads is it great. As an experiment I printed a recent design, the foundation for some organ themed knuckle dusters, in Shapeways’ ceramic. It was remarkably light and very pretty but a bit on the flimsy side. My dad took a shine to them when I was showing them off around the workshop and he, meaning to look like a fifties gangser, donned them and then brought his knuckles into his palm. Cue crunchy noises and falling bits. Alas.

Cultivating Style

I sit here, one of three folks all crammed on a futon, laptops steadily warming our laps, headphones plugged in, all persistently writing. To my right is designer, business owner, and furiously talented metal fabricator Danielle Hills. To my left is arch art director and wig stylist supreme Numidas Prasarn. The three of us collaborated to bring you these photos from Danielle’s most recent show, in which she exposed her brand new fashion line (The Executioner) to the world for the very first time.

You may recognize Danielle’s work from her previous collection, The Surgeon. She brings a unique, organic texture to her objects, while maintaining fairly simple geometries. The closest comparison I can think of offhand is Nervous System, but seen from a handcrafting perspective. You can view the whole series of shots I took of the event over on Flickr. There’s also some more coverage of the night here and here.

How They do That: The Sapporo Can

Many of you will be familiar with the tall, elegant Sapporo steel Sapporo can pictured on the right.  It’s a lovely tapered pint glass shape, with subtle creases every half inch along its surface. You might be curious as to why cans are almost never this shape, how the standard beer can is made, and what sets this one apart from a manufacturing perspective. In this post, I’m going to hunt through the clues left on the can itself to diagnose how this thing was made, and how the manufacturing process elegantly dictates the product’s final form.

The story of the standard aluminum can is fascinating. It goes from a simple disc of aluminum metal to a fully formed can in a scant few steps. How It’s Made has done a very complete diagnosis of the process, and The Engineer Guy has a brilliant video describing the function of the pull tab. However, the process for making one of them has almost nothing to do with the construction of one of Sapporo’s steel cans.
