Latvian artist [Krists Pudzens] just put on a show in Sweden and sent us the video of his amazing kinetic sculpture. (Embedded below.) We found an arty-theory writeup of another exhibition of his to share, but we had so many technical questions that we had to write him back asking for details. And boy, did he answer.
In the video, a couple of animatronic faces watch you as crab-like rope-climber bots inch upwards and red wings flap in the background. There’s a lot of brilliant mechanisms here, and aside from whatever it all means, we just like to watch machines go.
The details! Most of the pieces are plasma-cut steel or hand-cut-and-filed aluminum, and almost all of the motors are windshield wiper motors from old Russian KAMAZ and LADA cars. In another installation, the red wings (“Red Queens’ Race”) were installed in a public square and used to track the crowd, flapping faster as people moved more quickly by.
The robotic faces also use OpenCV to track you, and stare you down. One mask is vacuum-formed plastic, and the other is a copy in polyester resin and gelcoat. Here is a video of them on their own, and another of the development.
The twin rope-climbers, “Unbalanced Force”, just climb upwards at different paces. We were more than a little curious about what happens to the rope-climbers when they reach the top. [Krists] says the gallery staff grabs ladders and goes to fetch them. When he exhibited them in Poland on 20m ropes, they actually had to hire professional climbers. Life imitates art.
Some of us here at Hackaday are suckers for tech-art, whether it’s 3D-printed baroque columns, dancing with metal-bending machines, or just glowing globs of ferrofluid. There’s a lot of the same “wonder what would happen if…” tendency in the hacker and the artist — seeing possibilities and making them real.

A while back I wrote a piece titled, “It’s Time the Software People and Mechanical People Sat Down and Had a Talk“. It was mostly a reaction to what I believe to be a growing problem in the hacker community. Bad mechanical designs get passed on by what is essentially digital word of mouth. A sort of mythology grows around these bad designs, and they start to separate from science. Rather than combat this, people tend to defend them much like one would defend a favorite band or a painting. This comes out of various ignorance, which were covered in more detail in the original article.
There was an excellent discussion in the comments, which reaffirmed why I like writing for Hackaday so much. You guys seriously rock. After reading through the comments and thinking about it, some of my views have changed. Some have stayed the same.
It has nothing to do with software guys.
I definitely made a cognitive error. I think a lot of people who get into hardware hacking from the hobby world have a beginning in software. It makes sense, they’re already reading blogs like this one. Maybe they buy an Arduino and start messing around. It’s not long before they buy a 3D printer, and then naturally want to contribute back.
Since a larger portion of amateur mechanical designers come from software, it would make sense that when I had a bad interaction with someone over a design critique, they would be end up coming at it from a software perspective. So with a sample size too small, that didn’t fully take into account my positive interactions along with the negative ones, I made a false generalization. Sorry. When I sat down to think about it, I could easily have written an article titled, “It’s time the amateur mechanical designers and the professionals had a talk.” with the same point at the end.
Though, the part about hardware costs still applies.
I started out rather aggressively by stating that software people don’t understand the cost of physical things. I would, change that to: “anyone who hasn’t designed a physical product from napkin to market doesn’t understand the cost of things.”

With the advances in rapid prototyping, there’s been a huge influx of people in the physical realm of hacking. While my overall view of this development is positive, I’ve noticed a schism forming in the community. I’m going to have to call a group out. I think it stems from a fundamental refusal of software folks to change their ways of thinking to some of the real aspects of working in the physical realm, so-to-speak. The problem, I think, comes down to three things: dismissal of cost, favoring modularity over understanding, and a resulting insistence that there’s nothing to learn.
