3 Best STEM Toys for Adults to Learn Coding and Engineering
Adults learning to code often get further when the code does something physical. A robot that won’t turn or a drone that drifts off course makes a bug obvious in a way a spreadsheet exercise doesn’t. The three picks below are real learning platforms rather than novelty gadgets, and each suits a different kind of adult learner: one leans into mechanical engineering, one into Python, and one into writing code for a robot that’s ready to go.
One honest caveat up front: none of these is made specifically for adults. All three come from education companies, and their lessons are pitched at students. For an adult, the value is the hardware and the real programming tools, not the classroom framing.
We chose these from the makers’ own product, support and documentation pages, not hands-on testing. Ages, features and requirements are the makers’; the notes on fit are our judgment. Prices and stock change, so check with the seller before you buy. STEMGeek may earn a commission if you buy through some links on this page.
The three picks at a glance
| Pick | Best for | Languages and tools | Computer or device needed |
|---|---|---|---|
| Makeblock mBot Ultimate | Mechanical building plus Arduino coding | Scratch-based mBlock, Arduino IDE; Python with an added Raspberry Pi | Computer for mBlock or Arduino IDE |
| Robolink CoDrone EDU | Learning Python with a flying result | Blockly, Python | Windows or Mac for Python; Chromebook for Blockly only; no tablets |
| Sphero RVR+ | Coding a ready-built robot and adding hardware | Drawing, blocks, JavaScript, Python | Phone, tablet or computer |
Our picks
1. Makeblock mBot Ultimate
From the maker:
- Makeblock mBot Ultimate, ages 12+, sold as a 10-in-1 robot kit. Makeblock’s support documentation, which uses the name Ultimate 2.0, describes ten build configurations.
- Programmed with Makeblock’s Scratch-based mBlock software or the Arduino IDE.
- Python requires connecting a Raspberry Pi, plus setup and firmware changes.
Why it’s on the list: It offers the most engineering of the three. Rebuilding the same parts into ten different machines teaches mechanical design, not just code, which suits an adult who is as curious about gears and frames as programming. The Arduino IDE is the same environment many hobbyists use for their own electronics projects, so what you learn carries over once you’re past the kit.
Keep in mind: This is the biggest build here, so plan for a project rather than an evening. Python isn’t available out of the box: you’d need to add a Raspberry Pi and work through Makeblock’s setup and firmware steps, so check the listing for what’s included. Buy it by its current name. Older listings for a Makeblock “Ultimate Robot Kit” may not be the same bundle. Makeblock’s US store says it ships only to the contiguous United States.

2. Robolink CoDrone EDU
From the maker:
- A programmable learning drone, ages 12+, coded in Blockly or Python.
- Works with Windows, macOS and Chromebook, but Python isn’t supported on Chromebook, and iPads and other tablets aren’t supported. Robolink’s setup guide calls for a computer with a USB-A connection.
- The kit includes a smart controller (two AA batteries, not included), two rechargeable drone batteries, a charger and spare propellers.
Why it’s on the list: It’s the pick for learning Python through flight, where your code makes something fly. A flight path is unforgiving feedback: if a loop or a value is wrong, the drone shows you straight away. Starting in Blockly and moving to Python on the same hardware also suits adults who want a gentle first week before typing code.
Keep in mind: Check your computer first. For Python you need Windows or macOS, and you’ll need a USB-A port or a suitable adapter. Buy two AA batteries for the controller, and give it clear space to fly while following Robolink’s instructions. It replaces the CoDrone Mini listed in earlier versions of this guide. CoDrone EDU is a different model, so look for the EDU name.
3. Sphero RVR+
From the maker:
- Sphero RVR+, SKU 940-0635, designed for grades 6–12.
- A programmable driving robot with onboard sensors, a rechargeable removable battery and expansion ports for add-on hardware.
- Coded through the Sphero Edu app or its browser version, using drawing, blocks, JavaScript or Python.
Why it’s on the list: If you’d rather spend your time writing code than building a chassis, RVR+ is the quickest start of the three. You can skip the drawing and block modes and go straight to JavaScript or Python, and the expansion ports give the robot somewhere to go once you want to add your own hardware.
Keep in mind: Sphero makes RVR+ for schools, with a grade 6–12 label and lessons to match, so an adult who already codes may find the guided material basic. Its product page can default to classroom packs, so select the single-robot option and confirm the price. You’ll need a phone, tablet or computer for Sphero Edu.
How to choose
- You like building as much as coding: Makeblock mBot Ultimate, especially if Arduino interests you.
- You want to learn Python and have a Windows PC or Mac: Robolink CoDrone EDU.
- You want to write code on day one and add hardware later: Sphero RVR+.
- Match the computer to the product. Device support differs sharply between these three, and a Chromebook or tablet rules some options out. Check each maker’s requirements before buying.
- Be realistic about the lessons. These are education products. Beginners will appreciate the structure; experienced programmers are buying the hardware.
You may see LEGO Mindstorms Robot Inventor (51515) on older adult coding lists. LEGO marks it as a retired product, so it’s not included here for new buyers.
