Best STEM Robot Kits for Kids Aged 6-12: Beginner-Friendly Coding and Building Sets

Hi! I'm Maya, and I'm 10 years old. My parents got me really interested in robots and coding last year, and now I've tested tons of different robot kits. In this article, I'm going to share my honest reviews of the best robot kits for kids like me, along with some helpful advice from my mom and dad. Whether you're just starting out or you already know some programming, I've got something for you!

What Makes a Great Robot Kit for Kids?

Before I talk about the specific robot kits I've tested, I want to explain what I think makes a really good one. First, it needs to be fun. If you're not having fun, why would you want to keep learning? Second, it should be something you can actually build yourself, even if you're a beginner. I don't like when the instructions are super confusing or when you need a grown-up to help with every single step.

Third, a good robot kit should teach you real skills that you can use on other projects. I like kits that either teach you real programming or real engineering, not just pushing buttons. And finally, it should work the way it's supposed to work. I've had some kits where nothing worked right out of the box, and that's really frustrating.

Parent Commentary: Age-Appropriate Coding Skills

As Maya's parents, we've noticed that kids aged 6-8 benefit most from block-based visual coding and screen-free robotics, while kids aged 9-12 are ready for both visual and text-based programming. The best robot kits for younger children (6-8) focus on problem-solving and spatial reasoning. For older children (9-12), kits that introduce real programming languages like Python or JavaScript add a new dimension to learning. The ideal kit for your child depends on their comfort with technology, patience level, and interest in building versus programming.

Our Top STEM Robot Kits for Kids

1. Botley 2.0

$49.99

Age Range: 4-8 years old

Botley 2.0 was actually the very first robot I ever used, and it's still awesome. It's this little robot that's about the size of your hand, and it doesn't need a computer or tablet to work. Instead, you program it using this special remote control with different buttons. You press the buttons in different patterns, and then Botley follows your instructions.

The thing I really love about Botley is that it's so easy to use. You don't need to know anything about computers to get started. The instructions are really clear, and there are lots of fun challenge cards that teach you how to think about programming. My little cousin who's only 4 can even use it with a little help from grown-ups.

Pros:

  • No need for a computer or app - completely screen-free
  • Very affordable and durable
  • Comes with obstacle course pieces and challenge cards
  • Great for introducing the basics of sequencing and logic
  • Easy to use right out of the box

Cons:

  • Limited programming concepts compared to advanced kits
  • Programming with the remote control gets repetitive for older kids
  • Not as many expansion possibilities

2. makeblock mBot

$79.99

Age Range: 8-12 years old

The mBot was probably the kit that excited me the most. It's a little car-like robot that you build yourself with a screwdriver. When I opened the box, there were all these metal parts and circuit boards, and I was actually a little nervous about putting it together. But the instructions were way better than I expected, and I had it working in about 45 minutes with my dad helping a little bit.

What makes mBot special is that you program it using Scratch, which is a visual programming language that's used in computer classes in lots of schools. You drag and drop colored blocks to tell the robot what to do. The best part is that you can program the robot to do almost anything - move forward and backward, turn, follow a line, and even detect obstacles. I've made my mBot do some pretty cool things, like follow a black line on the ground and stop when it gets close to a wall.

Pros:

  • Teaches real programming with Scratch (used in schools)
  • Can be expanded with additional sensors and modules
  • Good balance of building and programming
  • Connects via Bluetooth to tablet or computer
  • Lots of online tutorials and community support
  • Affordable given what you can do with it

Cons:

  • Requires a computer or tablet to program
  • Building it for the first time takes some patience
  • Some sensors need extra setup to work properly

3. Sphero Mini

$49.99

Age Range: 8-12 years old

Okay, so the Sphero Mini is different from the other robots I've tested because it's actually round - it's basically a little robot ball. You control it using an app on your phone or tablet, and you can program it to do different things like move around an obstacle course, change colors, or even follow a maze you've drawn out on paper.

My favorite thing about Sphero Mini is that it's so satisfying to play with. There's something really fun about watching this little ball roll around and do exactly what you programmed it to do. It also comes with a really cool drawing mode where you can use the app to make the robot draw patterns on paper with a marker holder. I've spent hours making designs with mine.

Pros:

  • Super fun and engaging to use
  • App is intuitive and easy to learn
  • Durable - I've dropped mine many times
  • Cool drawing mode for creative projects
  • Good for both programming and free play

Cons:

  • Requires a smartphone or tablet to use
  • Battery life is only about 1-2 hours
  • Limited to what the official app can do
  • Limited advanced programming options

4. LEGO Boost Creative Toolbox

$159.99

Age Range: 7-12 years old

I know LEGO Boost is more expensive, but it's actually really worth it if you already love building with LEGO. The cool thing about this kit is that you use real LEGO bricks to build different robots and machines, and then you program them using the LEGO Boost app on a tablet. You can build over 60 different models, from a robot cat to a vehicle with a grabber arm.

The programming part uses colorful visual blocks, so it's easy to learn, but you can also do pretty complex things once you get the hang of it. I really appreciate that LEGO Boost lets you use your imagination to create your own designs while also giving you instructions for specific projects if you want them.

Pros:

  • If you love LEGO, this is perfect for you
  • Unlimited building possibilities
  • Good progression from simple to complex projects
  • Integrates with regular LEGO bricks
  • Fun characters and storylines in the app

Cons:

  • More expensive than other beginner kits
  • Requires a tablet to program
  • Can be overwhelming with so many building options
  • Motors aren't as powerful as some other kits

5. LEGO Mindstorms EV3

$299.99

Age Range: 10-16 years old (Advanced)

This is the most advanced robot kit on my list, and honestly, it's kind of expensive. But if you're really serious about robotics and you're a bit older, this is incredible. My older brother is 13, and he got a Mindstorms EV3, and he's doing some really impressive stuff with it. He's even thinking about joining the robotics club at his middle school because of it.

LEGO Mindstorms EV3 uses a programmable brick as the robot's brain, and you can add all kinds of sensors and motors to it. The programming is more complex than the other kits I've tested, but it's also much more powerful. You can use visual programming to start, but you can eventually move to Python if you want to learn real code.

Pros:

  • Industry standard for robotics competitions
  • Incredibly powerful and flexible
  • Can grow with your skills for many years
  • Tons of community support and resources
  • Can program in multiple languages

Cons:

  • Very expensive compared to beginner kits
  • Steep learning curve for beginners
  • Takes longer to build and program
  • Better for kids aged 10 and up

6. Snap Circuits Rover

$59.99

Age Range: 8-12 years old

Snap Circuits is unique because it teaches electronics in a really visual and fun way. Instead of programming, you're building circuits by snapping together color-coded blocks. The Rover kit includes a motorized base, so you build circuits and see how they control the robot's movement. It's like learning real electronics, not just programming.

I really like this kit because it's completely different from the other robot kits I've tested. If you want to understand how robots actually work on the hardware level - not just how to program them - this is perfect. My dad says it's teaching me things that people used to learn in high school electronics class.

Pros:

  • Teaches real electronics concepts
  • No computers or tablets required
  • Interactive and engaging
  • Color-coded pieces make it easy to follow circuits
  • Multiple projects in one kit

Cons:

  • Different approach than traditional programming
  • Not as flashy or tech-focused as other kits
  • Smaller robot movements compared to other kits

How to Choose the Right Robot Kit for Your Child

With so many options, it can be hard to know which robot kit is right for your kid. Here are the questions I think you should ask yourself before buying one:

Question 1: What's Your Child's Age?

This is really important. If your child is under 8, stick with Botley 2.0 or maybe LEGO Boost if they already love LEGO. Kids older than 8 can handle the mBot or Sphero Mini. If they're 10 or older and want to get really into robotics, the LEGO Mindstorms is worth the investment.

Question 2: Do You Want It Screen-Free?

Some parents told me they prefer their kids to play with something that doesn't involve screens. If that's you, go with Botley 2.0 or Snap Circuits. If you don't mind screens, the mBot and Sphero Mini are more advanced and fun.

Question 3: Does Your Child Like Building?

If your child loves building things and has a lot of patience, LEGO Boost or LEGO Mindstorms are perfect because the building is half the fun. If they want to start programming right away, the mBot is better because you build it once and then focus on programming.

Question 4: What's Your Budget?

Honestly, you don't need to spend a lot of money to start. The Botley 2.0 is amazing at $49.99, and the mBot is only $79.99 but teaches real programming. The expensive kits are great, but they're better if you know your child is really into robotics.

Tips for Getting the Most Out of Your Robot Kit

Once you get your robot kit, here are some things that helped me learn faster and have more fun:

STEM Skills You'll Learn with Robot Kits

I asked my teacher and my parents what skills I'm actually developing with robot kits, and here's what they said I'm learning:

Frequently Asked Questions About Kids Robot Kits

Q: How long does it take to build a robot?

A: It depends on the kit. Botley is ready to go in minutes. The mBot takes about 45 minutes to an hour the first time. LEGO kits can take 1-3 hours depending on the model. LEGO Mindstorms can take even longer if you're building a complex robot.

Q: Do I need to know how to code before getting a robot kit?

A: Not at all! Most robot kits are designed to teach you coding from scratch. I didn't know anything about coding when I started with Botley, and now I'm pretty good at it. The kits teach you as you go.

Q: Can girls use robot kits? (This is an important question!)

A: Yes, absolutely! Robotics and coding are for everyone. Some of the best robot programmers I know are girls. Don't let anyone tell you that engineering and robotics aren't for you.

Q: What happens if something breaks?

A: Most of the time, if something breaks, you can fix it. The companies usually sell replacement parts. I've broken things and replaced them myself. It's actually a good learning experience.

Q: Can my kid use a robot kit at school?

A: Many schools have robotics clubs and after-school programs that use kits like the mBot and LEGO Mindstorms. Ask your school if they have a robotics program. Some libraries also have robot kits you can use for free.

Q: What's the difference between a robot kit and a programming toy?

A: A robot kit is something you build and program to do specific things. A programming toy is usually pre-made and focuses more on the programming part. Robot kits are usually better if you want to learn both building and programming.

Q: Is it worth buying an expensive kit right away?

A: I think you should start with a cheaper kit to see if your child is really into robotics. If they love it after a few months, then invest in a better kit. Spending $50 to see if they like robotics is better than spending $300 on something they might not use.

Q: How can I help my child without doing it for them?

A: Ask them questions instead of giving them answers. Like "What do you think will happen if you change that number?" or "Let's read the instructions together to see what this part does." My parents are really good at this, and it helps me learn way faster than if they just fixed things for me.

Final Thoughts from Our 10-Year-Old Reviewer

Okay, so which robot kit should you actually get? Here's my honest answer: it depends on what your kid likes and how much you want to spend. If I had to pick just one to recommend to everyone, I'd say the makeblock mBot. It's affordable, it teaches real programming that you'll use in school, and it's actually fun to play with once you build it.

But if your child is younger, Botley is perfect and costs less. If you're really into LEGO and have the money, LEGO Boost is amazing. And if your kid is older and wants to get serious about robotics, LEGO Mindstorms is worth the investment.

The most important thing is that you get them something that will make them excited to learn. I've been playing with robot kits for over a year now, and I can honestly say that they've made me better at problem-solving and thinking logically. Plus, they're just really fun. I still play with my mBot and Botley even though I've had them for a while.

If you have any questions about any of these robot kits, or if you want to know about other kits I've tried, let me know in the comments. I love talking about robots!
