With the ability to adapt and change in response to the environment, Anki’s creation moves us ever closer to true AI for the masses.
And we haven’t even got to the fun part yet! The Cozmo Software Development Kit (SDK) is where the true magic begins. With the SDK, Anki put the power in your hands to develop your custom software for Cozmo. Some example scripts are provided, including turning Cozmo into an alarm clock, teaching him to sing a scale, or patrol the room for intruders. But the rest is up to your inner creativity…
There are tons of possibilities with access to higher-level functions like the vision system, localization system, animation & behavior systems, and path & motion planners. Cozmo can also connect to third-party APIs like Twitter and IFTTT, further expanding your possibilities. For example, you could tweet Cozmo to turn on your smart lights or program him to show an umbrella animation when it rains!
Furthermore, the SDK uses Python, one of the most widely used and dynamic programming languages. So you can also build a valuable and transferable skill by experimenting with the SDK. That is why Cozmo makes such an excellent coding toy for adults. Anki has given us an affordable robot with high-tech hardware that was previously only available in research labs. We can’t wait to see how Cozmo will help to advance robotics in the future!
3. Best Budget Option — Coogam Wooden Hexagon Puzzle

Coogam Wooden Hexagon Puzzle
An excellent game that you can play on your own or make it a game for two or more people.
Not all STEM toys for adults have to be about robotics, programming, or engineering! Sometimes, a good old puzzle can be just as satisfying. This Coogam Wooden Hexagon Puzzle doesn’t have any bells or whistles. Yet, it’s an absolute thrill for a lovely family evening.
You can play it on your own or make it a game for two or more people. The kids will also love it! With 14 pieces and over 60 challenges, the toy boosts logic and problem-solving. The best part is that there are always multiple ways to solve a particular puzzle.
So let’s see what you’ll get. There are a hexagonal wooden board and cardboard panels where the challenges are drawn. Each challenge shows a part of the puzzle. Place your pieces into the designated positions, and figure out a way to complete the puzzle!
It’s a simple yet efficient game for hours of fun and family bonding.
4. Best for Drone Fans — Robolink CoDrone Mini
Robolink CoDrone Mini
An innovative kit that enables you to program your own drone.
The only drone on our list of STEM toys for adults is CoDrone Pro by Robolink. This innovative kit enables you to program your own drone. Its predecessor, the Pro, went even further in that it allowed users to build a remote for the drone and then program it. But it was quite costly, so the manufacturer decided to tone it down and emphasize the coding aspect over engineering.
Anyhow, you can use the visual Blockly or even Python to program your own flight paths! Make sure also to check out video tutorials that teach fundamental coding concepts such as inputs and loops. Additionally, the Python coding language is composed of C, which is a widely used language. So again, you are building a valuable skill with real-world applications. That is why we recommend Codrone as one of the best programming toys for adults.
One thing is important to keep in mind, though. If you’re looking for a real and robust working drone you can fly high up, this is not it. What it can and will do is different acrobatics, which are impressive in their own right. Most of all, it will teach you coding. But you can’t expect it to carry a camera or anything like that. It’s not even recommended to fly it outside as it’s too small.
The only downside is relatively short battery life, but this is expectable for the price. After all, this is a learning resource as much as a toy. So it wouldn’t be fair to expect it to do things it wasn’t built to do.
Combined with the extensive online video tutorials and resources, we think this demonstrates the company cares about creating a great experience. That’s why we recommend them!
5. Best for Mechanics — ROBOTIME 3D Wooden Laser-Cut Air Vehicle Kit

ROBOTIME 3D Wooden Laser-Cut Air Vehicle Kit
One of the brightest examples of pure mechanics in a toy.
I’ve heard this argument so often: why do most modern STEM toys have to involve coding or programming? Well, those skills are in line with the zeitgeist.
But that doesn’t mean there are no other STEM toys! ROBOTIME 3D Wooden Vehicle Kit is one of the brightest examples of pure mechanics in a toy. You’ll get 349 bits, pieces, wheels, and cogs. All of them are laser cut, which means they are extremely precise and require no glue to hold them together.
Once you manage to assemble the vehicle, it will be an actual work of art that will make you proud. Best of all, you can disassemble it and start over!
If you like this kit, be sure to check out ROBOTIME’s other toys, such as their breathtaking Pendulum Clock – they make the Art in STEAM stand out!
Note, however, that this kit isn’t for people who are short on patience.
6. Best for Robotics Hobbyists — Makeblock DIY Ultimate Robot Kit

Makeblock DIY Ultimate Robot Kit
An awesome starter kit where you can build and program up to ten different robot models.
If you are looking for a slightly more affordable STEM toy for adults than Mindstorms, the Makeblock DIY Starter Kit is a great place to start. Similar to Mindstorms, this set is all about building and programming your robots. The kit comes with making instructions for ten models: robotic arm tank, self-balancing robot, robotic ant, rolling tank, catapult ram, camera dolly, and more. There are also many add-ons if you want to expand and build more!
Additionally, the components of Makeblock kits are all metal and might be a bit more durable than other kits. They also provide spare screws and nuts, which is excellent.
Makeblock is a great way to learn how to control physical objects using sensors, all through programming the Arduino or Raspberry Pi compatible Micro Controller board. You can do that in several ways. Firstly with Scratch 2.0 – a simple drag-and-drop based interface which involves dropping blocks of code into your desired sequence. That is a great way to learn the fundamentals.
You can also run text-based coding languages on Arduino like C or C++, which are more dynamic and efficient. All in all, we think Makeblock is a great coding toy for adults.
7. Best for Stress Relief — TrueBalance Coordination Game Balance Toy

TrueBalance Coordination Game Balance Toy
Looking for a fun way to de-stress? Stack seven rotating magnetic disks and make sure they won’t fall over! Sounds difficult? Think again!
How do you stack seven rotating magnetic disks so that they don’t fall over? Before you dismiss TrueBalance Toy as too simplistic, let me tell you that it’s harder than it looks. You will have to invest some considerable time in aligning all the disks.
And just when you think you’ve mastered it, you’ll realize it has so much more to offer. Try aligning the disks upside down or with your non-dominant hand.
You’ll have lots of fun with this toy on your own. But its real magic will shine through when you have friends over. Just bring it to the table and organize a contest! Before long, everyone will be fighting over it. A timer will spice things up even more.
A particularly great thing about this toy is that it will really help you de-stress and practice focus. That’s why it’s very suitable for people and kids with ADHD or on the autism spectrum.
What to Consider When Buying a STEM Toy for Adults
Is it a gift?
If you’re getting a STEM toy for yourself, that’s fine. But if you’re planning it as a gift for another person, you should keep in mind what their inclinations are. If they are into coding, they may or may not enjoy a purely mechanical toy.
If you aren’t sure about their preferences, it’s probably wise to get a toy that’s bound to be attractive to anyone. That means you should go for something that isn’t too specialized.
How complex is it?
Take the most elaborate and brilliant building kit in the world. It probably has over 1,000 pieces, and you can build dozens of various objects with it. But if you lack patience, the set will probably get out of the box just to go back in.
Complex toys are marvelous, but that doesn’t mean they should be everyone’s first choice. Sometimes, a simple product will do a better job of entertaining someone.
How open-ended is it?
We said above how too complicated a toy will be one person’s heaven and another person’s hell. Similarly, a toy that’s too simplistic will be plain boring to someone who is very much into tinkering and customizing.
For example, the best robotic toys will allow for open-ended play. It means that you can use them to build several pre-designed robots. But once you’re done with them, you can program just about any behavior if you know how.
Frequently Asked Questions
Do STEM toys work?
STEM toys are educational toys that teach fundamental principles about science, technology, engineering, and math. They may be designed for beginners, but don’t let that throw you off! Many of the toys start with the basics but have the scope to move into some advanced concepts.
From learning to code and build your own computer to constructing and programming your own robots, you will certainly benefit from tinkering with STEM toys.
What is STEM teaching and learning?
STEM consists of four disciplines: science, tech, engineering, and math. As a whole, though, it’s much more than just these aspects put together. It’s an interdisciplinary approach that fuses together different areas and encourages many essential skills to life.
Think of skills such as critical thinking, independence, courage to ask questions. Also, the courage to not give up just because you failed many times.
STEM is already profoundly incorporated into our youngsters’ education. But STEM toys are a great way for adults to either catch up or keep up with the trends. Even if you’ve never seen a robot before, it won’t stop you from learning how to build one from scratch. That’s what’s so awesome about these kits. They are excellent for beginners and teach you how engineering and programming work, even if you’ve never done it before.
Am I too old for toys?
You are never ‘too old,’ ‘too mature’ or ‘too smart’ to play with toys. Not only because they are a massive amount of fun, but because they are a great way to learn new skills. Skills which could one day land you a job!
It’s estimated that between 2014 and 2024, the number of jobs in Science, Technology, Engineering & Math (STEM) fields will grow by 17%. Conversely, non-STEM jobs are set to grow just 12%. But the benefits don’t stop there. STEM skills could also boost your earnings! That is where STEM toys for adults come into play – pun intended.
