Best Overall – Elegoo UNO R3 Smart Robot Car Kit
Elegoo UNO R3 Smart Robot Car Kit
Build a cute little robotic car and control it via infrared remote control or Bluetooth on your mobile app. Once you get enough of that, branch out its functionality by coding new behaviors!
But first, a note on Arduino, for those of you who aren’t familiar with it. Don’t worry, it’s nothing to freak out about!
Arduino is an open source platform used for building and programming all types of electronics projects. It’s basically a programmable mini-computer consisting of a micro-controller (circuit board) and some programming software.
The language used is a simplified version of the widely used C++ language, so it is great for beginners to learn the basics of coding. We won’t delve much further into it in this article, but you can find a good introduction here.
This kit comes with everything you need to build and control your own robotic RC car. For the price, it also includes some pretty cool bits of hardware. There are 4 motors, 1 servo motor, an ultrasonic sensor, Bluetooth, line tracking & obstacle avoidance modules, and all circuit boards and wiring. We also like how this set includes a built-in rechargeable battery pack – we have seen other sets that do not!
You will be guided through assembly with instructions and video tutorials on the CD included in the kit. However, some users also suggest using YouTube tutorials to help with this. You can find a good one below!
This really is a great budget engineering toy for adults. Furthermore, once you become familiar with the Arduino, there are hundreds of other projects out there. You are opening the door to loads more possibilities. As such, it is a great learning tool.
Another great electrical engineering toy for adults is the Smart Video Car by SunFounder. The main difference is that SunFounders operates with a Raspberry Pi – a microcomputer similar to Arduino.
Raspberry Pi kits are also trendy, but we will not go into them in this article.
Best Programmable Robotics Kit – LEGO Mindstorms 51515 Robot Inventor Kit
LEGO Mindstorms 51515 Robot Inventor Kit
A versatile and powerful kit for building and programming robots, the 51515 is equally suitable for complete beginners and experienced engineers.
LEGO buffs won’t be surprised that the 51515 Robot Inventor Kit is our second option. To be completely honest, the only reason we didn’t kick it up to #1 is its price. The reality is that not everyone will be able to dish out a significant amount of cash for a toy, however brilliant it is.
And this latest (and alas, possibly the last) iteration of Mindstorms really is brilliant. The fancy purple box shows five cool robots, but you can build many more than that.
Unlike its predecessor EV3, the 51515 has nearly 1,000 pieces. That’s some serious building work ahead of you! As for the robots you can build, the 14-inch tall humanoid Blast will probably be the most attractive. It can punch, hammer, shoot fire missiles, and give you high fives straight out of the box.
Charlie, a cute little robot friend, will dance and play drums. (Not very pleasing to the ear, we must admit!) There are also the vehicles M.V.P. and Tricky, as well as an amazing quadruped Gello. Who needs wheels to move when you have four amazingly engineered legs?!
These robots can perform over 50 activities readily available through the app. Along with the building time, that will provide weeks of fun! If you have LEGO Boost, you can use it to enhance your Mindstorms even further.
But the coding part is where this kit truly shines. Novice programmers can resort to Scratch visual coding, which doesn’t require any special skills. Those of you who have gone past the beginner level can do full-blown line-based coding. That really opens up endless possibilities! You can program these robots to the extent of full automation. That would probably take months or even longer. If that’s not an excellent bang for the buck, I don’t know what is!
Many LEGO fans are still fervent supporters of the previous EV3 iteration. Indeed, it’s been hands down the most revolutionary consumer robotics set.
However, the 51515 Robot Inventor comes with reduced weight and a rechargeable battery. Another advantage is the possibility of adding 6 motors. Many users feel that it offers more ease of use and better playability than the EV3.
Time will tell if its successor is going to beat this popularity. Anyways, the EV3 isn’t always available these days. It comes and goes out of stock, but you can definitely check it out.

Best Robotic Arm – LewanSoul Programmable Arm
LewanSoul Programmable Arm
A mighty and accurate robot arm that’s marvelous to build and experiment with!
Robotic arm sets are some of the best engineering kits for adults to learn how to build and control servo motors in a fun and interactive way. Given the prolific use of robotics arms in factory automation, we also think experimenting with these sets is a great way to learn skills that could be valuable in the industry.
Aside from that, they are also tons of fun!
When it comes to recommending the best robotic arm kit, one of the key considerations are the degrees of freedom (DOF). This relates to the number of rotational joints present in the arm, so it is essentially a measure of its flexibility. Another two important factors are the max payload – the mass it can lift, and the control element, i.e., is it remote-controlled, easily programmable, etc.
Based on these criteria, we believe the LewanSoul XArm is a good option. It may not be the cheapest option on the market, but the quality is very high due to the use of all metal components and high-end servo motors. The result being it can lift some 8 ounces with decent accuracy. Additionally, it also moves with 6 DOF, so it has excellent flexibility. Unlike many other similar robotic arm sets on the market that only offer 4 DOF!
The assembly of the arm is guided through a detailed 3D video tutorial. Through this process, you can learn some mechanical and electrical engineering concepts. Once the robotic arm is built, it can be controlled remotely with multiple options, including the Playstation-styled remote, IOS/Android mobile Apps, or even a mouse!
The third option is to program movements with the graphical PC software, which is good for learning coding concepts. Additional video tutorials are also provided to help beginners. Furthermore, more experienced coders can also connect a Raspberry Pi or Arduino Microcontroller to create more complex arm programs. See GitHub for more details!
Overall, we think the quality of build, programming/control options, and overall support for the LewanSoul xArm are fantastic for the price paid. Yes, you could find it cheaper on the market, but this would likely be at the cost of one of the above points.

What to Consider When Buying Engineering Toys for Adults
Does Age Really Matter?
If you read age labels, you might find yourself a bit disheartened. Not many engineering toy manufacturers will claim adults as their preferred customer base. Ages 4 to 7, 7 to 10, 10+, those are the most common labels you’ll see.
However, this exclusivity is slowly starting to reflect reality. And the reality is that many parents buy these kits for their kids and end up using them themselves. Most engineering kits are so elaborated that they have something for everyone.
So, don’t feel guilty if you want to buy such a toy for yourself. Contrary to what most people assume, play isn’t just for kids. It has many benefits for adults too, helping us cope with daily stress and refine our cognitive skills. Moreover, you’ll end up learning so much about mechanical or electrical engineering and even coding.
How much free time do you have?
Alas, leisure has become a luxury these days. And leisure is exactly what you need for productive and fulfilling play.
So, before you spend a hefty sum of money on a super cool robotics kit for adults, make sure you have the time to actually use it to its full potential. Elaborate projects require continuous effort, even if it’s as little as half an hour each day.
Many engineering toys for adults have excellent potential for open-ended STEM learning. That’s absolutely fine, but not everyone will want to flesh out their knowledge.
Some people are in it just for fun and a few hours of de-stressing. If that’s the case, you may want to go with a cheaper option that doesn’t offer growth opportunities.
Vice versa, if you seek an engineering kit that will keep stretching out your skills, you’ll want to invest in a premium kit.
The point is, you should figure out what a kit can do for you. But also what you can do with your kit!
