The choreography loop was 3:28 minutes long and I had to find out which speed in the pixelstick settings was needed to playback the final picturesize of 3000 x 100 pixels in time. Meanwhile I was working on the graphics and in a second step on the synchronisation-process between graphic lenghts, pixelstick speed-settings and the animationpath of the robot which I calculated with exel tabloids and a simple stopwatch. So first of all Johannes created a customized 3D print model for the KUKA-platform which we could exchange with the original pixelstick one so the shortened pixelstick would fit exactly on the robotarm. Johannes developed a direct powersupply coming from the robot which is also triggering the firebutton of the pixelstick once the robot restarts its choreography.
This robot nearly does the same but due to its weight it´s mobile. Now when it comes to a functional mobile installation version, the task was getting more and more technical. As this one is smaller, we decided to use only the half of the original pixelstick, so the picturesize was reduced to 100 pixels and as I knew from earlier tests, the half-version works aswell as soon as it gets the powersignal. So we switched over to its smaller brother the KUKA KR-16. Directly at the first test I saw its potential - exact animationpaths in combination with specific designed graphic layouts on the pixelstick blew my mind.īut we were relativly limited to certain timeslots and within the following two months we knew we had to develop a finished working version of the installation for the upcoming exhibition at Ars Electronica Center called "creative robotics". The big robot is permanently installed in the laboratory and not moveable.
First we had to find a choreography that works with a 2 meter long stick on the robots arm, as the basement doesn´t provide that much space. So it was in the end of November when I took my pixelstick with me and we directly mounted it on the big KUKA robot in the basement. As it turned out he is giving lectures at the Kunstuniversität Linz and head of their robotic laboratory.Ī couple of weeks later we met for the first time in the laboratory and had a chat about the optional collaboration. Chance was on my side when I connected with Johannes Braumann from Robots in Architecture that day. You must define the amount of LED pixels in your config as 122 for the 82cm strip.When I tumbled upon the robotic installation at Ars Electronica Festival in autumn 2015, I knew I have to get in touch with someone who´s on hold of these machanic toolarms. These are not approved for heavy dueling. Carefully chosen LED chips from reliable suppliers that offer the highest quality. For custom lengths we advise using flexible strips instead (we also carry those in our shop).
Higher pixel density - more than the traditional 144 LEDs per metre! Heavily tested copper thickness to ensure the best efficiency and voltage drop. Bigger, better, solder pads for improved efficiency. Rounded end on the PCB to make insertion into foam easier. LEDs mounted on both sides already staggered. This makes building led strip (often referred to as NeoPixel) blades faster and easier.
Gone are the days of peeling and sticking flexible strips, removing heat shrink, removing wires, catching flexible strips on foam and tearing it etc. In collaboration with The Saber Armory we are proud to offer their V2 KR ‘PIXEL STICK’ RIGID LED PCB STRIPS!
