Baby Octopuses, Traffic Jams, and Cubelets: Teaching Complex Systems in the Classroom

Flashback to an episode of Factor Ciencia filmed in 2023 at the Escuela Superior de Cómputo in Mexico City, where researchers shared a playful yet powerful way to teach complex systems—with Cubelets robot blocks. The lab’s team, led by Dr. Genaro Juárez, uses modular robots to model how simple rules can lead to surprisingly complex outcomes (Minute 7:00-11:20).

Their experiment? Mimicking the early movements of a baby octopus.

With just three Cubelets—a Battery Cubelet for power, a Drive Cubelet for movement, and a Flashlight Cubelet to glow with presence—students can watch as simple actions spark emergent behaviors. One Cubelet makes the robot move, another signals its existence, and together they form the foundation for something greater. When multiple Cubelet-based robots interact, patterns emerge: random walks transform into collective behaviors, self-organization takes shape, and new “organisms” are formed.

The brilliance of this demonstration is that it shows how complex systems don’t require complicated parts. Instead, they arise from simple interactions. Whether we’re studying the spread of a virus, migration patterns, or even daily traffic flow, the same lesson applies: complexity grows from simplicity.

For educators, Cubelets offer a tangible way to guide students through these big ideas. By starting with small builds and gradually scaling up to group experiments, students can:

      • See self-organization in action as their robots connect, combine, and evolve.

      • Draw parallels to real-world systems, from ecosystems to social networks.

      • Ask deeper questions about cause, effect, and unpredictability in natural and human-made systems.

    Like a baby octopus learning to swim, the journey begins with small movements that lead to surprising complexity. And with Cubelets, students don’t just read about these systems—they build them, explore them, and watch them evolve before their eyes.

    A Parallel Project: Building a Museum of Computing

    Alongside their robotics experiments, the lab also created Mexico’s first computer science museum. As Dr. Juárez explains, the country had never had a dedicated museum for computing. Years prior, Harold V. McIntosh built one, but after his passing, it disappeared.

    To preserve this history, the lab collected artifacts that showcase the evolution of technology—everything from floppy disks, operating systems, and circuit boards to vintage mobile phones, cassette tapes, early CPUs, projectors, and even old robots and toys. Each donated item contributes to a living archive of computer science, and contributors are honored on the museum’s list of supporters.

    The Cubelets experiments and the museum share a common theme: both remind us that innovation builds on the past. Just as simple Cubelets combine to form complex systems, generations of devices—from floppy disks to smartphones—combine to tell the story of human ingenuity.

    Bots in the Lab, Sparks in the Classroom https://modrobotics.com/teacher-feature/bots-in-the-lab-sparks-in-the-classroom/ Sat, 06 Sep 2025 05:31:38 +0000 https://modrobotics.com/?p=18884

    How STEAM teacher Emily Bracco uses Cubelets to turn problem-solving into pure excitement.

    Meet Emily Bracco — STEAM Lab teacher at The Christ School and an all-around champion of creativity, critical thinking, collaboration, and communication. Emily teaches transitional kindergarten through eighth grade STEAM, plus a middle school computer science course. Her students dive into the scientific method, design process, and plenty of hands-on problem-solving — and Cubelets have become a favorite part of the journey.

    “I mainly use Cubelets with middle school computer science class, but have used them with grades as low as third,” Emily explains. What she loves most is that “you don’t have to have a screen to use them, you are programming it as you build the bot! This helps to build the bridge between programming and robotics!!” For her students, Cubelets are a fun way to practice problem-solving and debugging, while building robots right in their hands.

    One of Emily’s favorite Cubelets lessons is a big hit: building a bot that can navigate a Keva plank maze. “I’ve been doing this lesson for 3 years now and always am discovering new creations from students to complete the challenge!” she shares. And when it comes to favorite builds, Emily says, “My favorite build is the light house! It’s also my favorite way to show off Cubelets when I’m introducing them for the first time!!”

    She also loves starting new groups with a robot scavenger hunt. “I love [hearing] student predictions about what the robots do,” Emily says. From day one, she notices how “students are always curious but [are especially] intrigued the first day we are working with Cubelets!” That excitement carries over as they begin inventing their own bots and experimenting with new combinations.

    The impact on students has been powerful. “I believe that Cubelets have positively impacted my students by catching their interest in STEAM/robotics,” Emily reflects. “Cubelets have [played] an integral role in helping students develop a love for learning and a love for robotics!” She highlights how Cubelets shine in The Christ School’s specialized program for students with dyslexia:

    “These students are so incredibly talented and creative and, more often than not, thrive in my classes. Cubelets have helped them to not only find a love for robotics, but have assisted in building their confidence that they can be successful and do great things!”

    Along the way, Cubelets have also surprised Emily. “[It really is] hands-on programming!” she says. “There are features that allow you to connect to a device, but I love that it can be a screen free option!”

    For other educators curious about Cubelets, Emily’s advice is simple: “They are easy to use and learn, even if you don’t have experience with robots or programming, the bots and systems are easy to follow, and the resources are great!!”

    In the end, Emily sums it up best: “I just really like working with Cubelets!! :)”

    Sparking Creativity: Cubelets in the School Library Makerspace https://modrobotics.com/teacher-feature/sparking-creativity-cubelets-in-the-school-library-makerspace/ Thu, 04 Apr 2024 14:19:18 +0000 https://modrobotics.com/?p=16327

    As the library media specialist at Avail Academy in Edina, Minnesota, Karen Christensson has been utilizing Cubelets in her makerspace for three years. During each day’s forty-five minute library periods, students participate in different makerspace activities that encourage a hands-on approach to learning and problem-solving. Cubelets are one of the stations offered to all third, fourth, and fifth graders at her school. 

    Thanks to the versatility of Cubelets, Mrs. Christensson is able to provide her students with different robot examples to kickstart their creativity. Her students use these examples as jumping-off points for their own robots. 

    “The students love to create Cubelets models using their own imaginations and LEGOs,” she says. “I have only shown the students examples of what they can build and let them take off from there.”

    “A favorite [Cubelets challenge] in my library is to use as many Cubelets as possible in one build, with as many lights and sounds and LEGOs as possible!” she adds.

    Myra Gallardo, another library media specialist, teaches at East Pennsboro Elementary School in Enola, Pennsylvania. She sees a diverse range of students on a daily basis, and has recently started using Cubelets with her kindergarten through fifth-grade students.

    Mrs. Gallardo divides her students into groups of two or three, and ensures that each group has access to a tub filled with the three different Cubelets types—SENSE, THINK, and ACT. Depending on the activity they are doing that day, each group might also receive a second or third Battery Cubelet.

    Even though she is in the early stages of implementation, Mrs. Gallardo has already observed the impact Cubelets have had on her students. During the initial lessons, which focused on free play and learning about the robots, students were excited and engaged. Subsequent lessons introduced challenges such as creating slow and fast robots, making robots perform wheelies, and even crafting animal-like creations using Cubelets. For more ideas like these, educators can check out the Cubelets Activity Cards.

    “I think Cubelets give students confidence and pride,” Mrs. Gallardo says. “School is hard for some students, and the joy and pride when they build with Cubelets makes them excited for their accomplishments.” Learning to celebrate one’s own accomplishments in any school environment drastically improves learning outcomes for students across subject areas. Cubelets can be the launchpad for academic curiosity and confidence.

    One of the positive aspects of Cubelets, according to Mrs. Gallardo, is their accessibility. “From kindergarten to fifth grade, from special needs to gifted, all students have success and fun building with Cubelets,” she says. This is one of the traits that make Cubelets stand out in the EdTech marketplace. Cubelets can truly be used by every single student in a meaningful and enriching way. Educators who want to know more about how to adapt the Cubelets curriculum for additional accessibility can check out the DeBug’d curriculum, available here.

    Another advantage of Cubelets is the autonomy they give students. Back at Avail Academy in Minnesota, Ms. Christensson recalls how two fourth-grade students used an iPad loaded with the Cubelets app to teach themselves how to remotely control their Cubelets robot. This is a testament to the power of exploration and self-directed discovery that Cubelets enable. (Little did these students know that behind the power of Remote Control lies the ability to Read Your Robot when you want to learn more about how data moves within your robot system!). 

    As for what she’s learned from using Cubelets, Mrs. Christensson says, “I learned to relax when giving the Cubelets to the kids to play with. It was surprising to me how innovative they could be using a small case of Cubelets.”

    Mrs. Gallardo has learned that Cubelets are a great option for makerspace play. Students “create and laugh and want to show the world their cool construction,” she says. 

    She also notes that Cubelets have universal appeal for her students, and says, “No unhappy customers on days when Cubelets are out!”

    As Mrs. Gallardo continues to integrate Cubelets into her curriculum, she looks forward to facilitating further opportunities for exploration, creativity, and learning among her students. Meanwhile, Ms. Christensson finds it rewarding to watch students unlock their creative potential and showcase their ingenuity with Cubelets. 

    With Cubelets leading the way, the future of education is bright, innovative, and full of endless possibilities.

    Teacher Feature: Barbie Atkinson https://modrobotics.com/teacher-feature/teacher-feature-barbie-atkinson/ Wed, 15 Feb 2023 15:57:00 +0000 https://modrobotics.com/?p=12373

    Barbie Atkinson has been using Cubelets for four years in her role as media clerk for Park Hill Elementary in Derby, Kansas. As an educator, she enjoys activities with students of all ages throughout the day, where Cubelets are a school-wide favorite for even the youngest learners. 

    “Cubelets make [the students] more confident learners,” Atkinson says. “It’s a great, engaging learning tool.” 

    Like many educators who purchase Cubelets, Barbie acquired her kit with the help of a grant. As Park Hill Elementary serves a large military family population, they received a grant from the Department of Defense Education Activity to improve the academic achievement of military-connected students in STEM.

    Atkinson notes that students who are working with Cubelets for the first time often start out by building a lighthouse, or making animal creations with them. Robot races are also a popular activity, and Atkinson has created mazes for her students’ robots using tape on the floor. Another one of her favorite activities is to draw a solid black line on a piece of paper, and then challenge her students to create a robot that follows the drawn path. Educators who are looking for robot inspiration can visit the  Cubelets Robot Ideas webpage for additional builds!   

    Resources for helping students (and educators!) can be found on the Modular Robotics Resource Hub online–everything from introductory courses for teachers and simple activities for young learners to more complex computer science units.

    “Don’t be afraid!” Atkinson advises educators who are also using Cubelets for the first time. “Cubelets are user-friendly and easy to get started with.” 

    Atkinson also praised the exceptional customer support provided by Modular Robotics.

    “[They are] very quick to respond with email questions,” Atkinson said. “They also have been amazing when a Cubelet has stopped working. I was able to mail the broken cubes in and very quickly got some returned that are working well.” 

    In addition to being easy to get started with, Atkinson says that Cubelets are a great way to fill the end of a day with something that is both educational and fun.

    “Need an educational activity to fill the end of a day–perhaps the last hour after a field trip when students are exhausted and overstimulated?” she says. “Pull out the Cubelets! They are a perfect activity to fill that time.”

    A No Longer New Kind of Science https://modrobotics.com/uncategorized/a-no-longer-new-kind-of-science/ Thu, 15 Dec 2022 17:42:19 +0000 https://modrobotics.com/?p=10795 We think about Cubelets in a lot of different ways, but when we were inventing them back in the mid 2000s at Carnegie Mellon, I thought of them mostly as a tangible, three-dimensional form of cellular automata. Consider it a reflection of all the computer science papers I was reading at the time. I was fascinated by distributed systems (as opposed to robots with just one brain), and Stephen Wolfram’s New Kind of Science had been published just a few years prior.

    These days we usually think about Cubelets as design tools for kids. But I’m thrilled when people push the ceiling higher with Cubelets. Here, Genaro Juarez Martinez at IPN in Mexico (and a number of other colleagues, academic project is here) has built a Post machine out of Cubelets and some LEGO. A Post machine is a kind of universal computing model, like a Turing machine. Theoretically, this machine could calculate anything. And here it is, running on a bunch of parallel Cubelets, calculating some very small things.

    The cool part here at the end is that Wolfram has included the Cubelets Post Machine in his Twenty Years of a New Kind of Science, a reflection about progress in cellular automata research over the last two decades. I’m pretty excited that Cubelets are part of that story!

    Happy Buy Nothing Day https://modrobotics.com/holiday/happy-buy-nothing-day/ https://modrobotics.com/holiday/happy-buy-nothing-day/#respond Fri, 25 Nov 2022 13:33:49 +0000 https://modrobotics.com/?p=10791

    It’s the day after Thanksgiving in the USA, and after a holiday hopefully filled with family, gratitude, and a good meal, it feels like the country descends into a tasteless consumerist chaos today for Black Friday. Happily for me, our family escapes this madness and has celebrated Buy Nothing Day for many years.

    I guess traditionally, people consider the holiday season to start right after Thanksgiving ends, and with an extra day off work, Friday was a good time to think about buying gifts. Retailers noticed this, of course, and started offering discounts to draw shoppers to their store instead of others. Capitalism and free markets took over and at some point we ended up with people fighting each other to get great deals on TVs and cheap consumer crap. Not only is it viscerally depressing, it portends a sad trend toward consumerism and disposability that makes me feel a bit grim about the future.

    I don’t mean to be super negative today, but we can’t go on like this. We all know it, I think. But beyond not shopping today, what might positive change look like? Mitch, our Head of Customer Support, posted a link to this excellent article about Uruguay, and how along with top-down sustainability regulation, they’ve managed to foster a bottom-up culture of re-use and anti-consumerism. It’s not an example that will map directly to a country like the USA with 100 times the population, but it’s full of ideas and stories that might give us the energy to effect positive change in our own ways.

    So no, with apologies, Modular Robotics doesn’t offer special deals or discounts or reasons to fight with your neighbors on the day after Thanksgiving. Black Friday doesn’t fit with our values so we don’t participate. I hope you have a wonderful weekend and are able to spend some time this holiday season with people you love!

    Teacher Feature: Kasey Herzberg https://modrobotics.com/teacher-feature/teacher-feature-kasey-herzberg/ Wed, 16 Nov 2022 15:54:12 +0000 https://modrobotics.com/?p=12370

    Kasey Herzberg is the Executive Director of the Challenger Learning Center of Minnesota, a nonprofit working to bring a unique and powerful STEM education center to the state. Her mission is to build confidence in students in the areas of science, technology, and engineering, and to create a lifelong passion for these topics.

    Herzberg uses Cubelets to run STEM and robotics after-school workshops for students in grades 1-8. She and her staff have found that putting robotics in the hands of students at an early age boosts confidence, which in turn shows students that science is fun and exciting, not scary. She says that Cubelets in particular are effective in sparking curiosity, shaping effective communication and collaboration skills, and teaching students how to work well together on a team. 

    “We love to build confidence in these students and encourage them to dream big!” she says. 

    One of Herzberg’s favorite activities to do with her students is the Racing Robot. The challenge is to design a robot that can carry an object to its destination in the fastest amount of time. Herzberg uses this challenge to introduce students to the Engineering Design Process (EDP), a series of steps that engineers follow in order to find a solution to a problem. 

    One of the most rewarding experiences Herzberg has had with Cubelets was when she was doing a Girls in STEM after-school workshop. One of the students had never been introduced to robotics before, and didn’t even want to try building a robot because she believed she wouldn’t be successful. At the end of the workshop, however, the student was running after a robot that she had built and said that now she wanted to be an engineer. 

    “The Cubelets did exactly what we had hoped,” Herzberg says. “They showed her that science was fun, tangible, and not scary.

    “I wish every educator knew how easy Cubelets were to use and how impactful they are in the classroom,” she goes on. “These small computers pack a large punch when it comes to hands-on STEM learning that really fosters imagination, inspiration, and creative collaboration.”
