Our Review of Modular Robotics Cubelets Discovery Set

This year, we got to review a cool robotic toy for kids. Cubelets is a product by Modular Robotics that allows kids as young as 4 explore and create. The kit we reviewed back in April was the Twelve Kit. This one is the more basic Discovery Set.

What you get in the Cubelets Discovery Set

This kit is composed of 5 robotic cubes that have different functions you can put together to build mini robots. The pieces are magnetic, so they are easy to put together. In this basic set, you get

  • 1 Battery Cubelet
  • 1 Brightness Cubelet
  • 1 Drive Cubelet
  • 1 Distance Cubelet
  • 1 Flashlight Cubelet
  • 1 Bluetooth Hat
  • 2 Brick Adapters
  • 1 Micro-USB Cable
  • A guide to building different robots with your kit

The battery Cubelet is what you charge and add to your creations to power them up. The brightness Cubelet will allow your robot creation to sense light and dark. The drive Cubelet has wheels to help the creation move. The distance Cubelet is another sensing one that determines how close it is to another object. The flashlight Cubelet has a light that can brighten and dim. The free downloadable apps pair with the Bluetooth hat so you can control your robot with the app. The male and female brick adapters will allow you to add Lego, or other brick building toys to your creation.

More About the Cubelets

These are some of the things you can build with this basic kit:

Of course, you can buy more Cubelets and other kits to build different functioning robots. There are Cubelets to detect temperature and a speaker Cubelet so your robots can make noise.

How to buy Cubelets

This particular set costs $139.95 Other kits have different costs, and you can even buy individual blocks. This would make an excellent gift for the aspiring young robotics engineer in your life.

A Review of Cublets Robot Blocks Twelve Kit from Modular Robotics

I have to admit, when I received the Cubelets to review, I couldn’t help but compare it to the Makerblock Neuron Inventor Kit that I just reviewed. Is it coming to the point where I’m reviewing a STEM product every week? If so, I’m cool with it.

So, let’s talk Cubelets. I don’t think I could have done this review if it wasn’t for my son, because he was really into them. Unlike a lot of STEM toys, which seem to emphasize coding, the Cubelets emphasizes creation. When my son started working with the Cubelets Twelve Kit, it was difficult getting him to quit.

When you get the Cubelets, they come in this box where they are packed in a particular pattern. You see, these Cubelets essentially lock together with magnets, and they come in a 2 x 4 formation, with another 2 cubes on each side. I hope that isn’t too confusing of a description, and I might have to do some kind of unboxing to really show off this product, hmmmm…..

So here’s the deal. Each of the Cubelets has a function, and by connecting them together in different ways, you can make a kind of machine that can do all kinds of things. Fortunately, it came with instructions.

I’ll start with the Battery Block, which can be charged with a micro-USB. I noticed the Flashlight Block with a light bulb, and so I connected the Battery Block with it and turned it on. I saw a small green light on the Battery Block, and there was a small light on the Flashlight Block as well.

However, the bulb on Flashlight didn’t glow. I wondered if I did something wrong, but I then connected one of the Distance Blocks (yes, there are two of these particular Cubelets). This Distance Block had a sensor that could detect my hand in front of it, and when connected to the Battery Block and Flashlight Block, I created a luminescent flashlight that allowed me to change the brightness as my hand got closer to it. Granted, covering the Distance Block didn’t do anything, but you see what I am getting at. You see, I could magnetically lock these three blocks together in just about any order, and it worked.

So then I tried the Brightness Block, and I had a flashlight that was somewhat solar powered. The more light I shown on the brightness sensor of the Brightness Block, the brighter the Flashlight Block shone.

Are you getting this now? So let’s hook up the Drive Block, or two of them, because there are two. The Drive Block has these two rollers that look like small rolling pins. I can control their speeds in the same way that I controlled the brightness of the Flashlight Blocks.

So, yes, there is a lot that you can do with these. There are some other blocks like the Passive Block, which is like a wire of this Cubelets (that makes sense if you work with them). Then there is the Blocker Brick, capable of blocking a signal. What is really interesting is the Inverse Block, which essentially makes the Distance Block or Brightness Block have the opposite effect.

So there really is a lot you can do with this, and there is even a Bluetooth Block so you can sync it to your smartphone or tablet. To make this even more constructive, it comes with a male and female LEGO compatible brick. When you use these, you can make LEGO creations spin and go, just like some Technic or even MINDSTORMS creations.

I believe that the Cubelets is one of the finest educational toys, and the Twelve kits are available on the Modular Robotics site for $275.00.
