Teacher appreciation week starts on Monday, and we want to make sure you know just how much we appreciate all the hard work you do. So to celebrate you, we’re giving away prizes all week, and one grand prize winner will receive a Cubelets Curiosity Set! All you need to do to get in on the action is tweet a story or photo of how you use (or would like to use) Cubelets with the hashtag #CubeletsChat and tag @ModRobotics. Each new story will be considered one entry, and even if you win one of the daily giveaways, you’re still entered to win the grand prize! The random drawings will happen at 4pm MT, daily, from May 6 – 10, 2019, with the grand prize winner chosen on Friday, May 10 2019.

Indeed you can!  Do you know what a Turing Machine is? It’s a type of a computer, or, well, it’s a model of a computer. A simplified computer, with a memory tape and a read/write head that moves back and forth along the tape. It’s a funny little type of a computer, but it’s interesting in that with a Turing Machine, you can do any kind of digital computation that we can think of. Maybe not in a super optimized fashion, but… LOOK! Here’s a Turing Machine made with Cubelets and some LEGO bricks: This construction was built by Genaro J. Martínez and students and collaborators at ALIROB (Artificial Life Robotics Lab) in Mexico. I think it’s brilliant. There’s a web site with a few more videos and all of the code has been published there too. You’ll see a ton of neat little programming features in these robots:  Rotate Cubelets, for example, can only be controlled by specifying a speed, not a position.  Check out how they use a distance Cubelet as a “stop” to recalibrate the little swinging arm after each swing. Most of the Cubelets we make end up in elementary or middle school classrooms.   So we spend a lot of time working on making Cubelets accessible, educational, and intriguing: focusing on the low-threshold aspects more than the high-ceiling aspects.  It’s nice to be reminded that Cubelets are actually a universal computational material, a medium, capable of supporting some pretty advanced thought experiments.
