Create intelligent remote-control robots and vehicles using interactive in-app building instructions, with the LEGO® MINDSTORMS® Robot Inventor App! For use with the LEGO MINDSTORMS Robot Inventor (51515) set, this companion app has everything you need to build Charlie, Tricky, Blast, M.V.P. and Gelo, each with their own unique abilities. Then get ready to code and play your way through 50+ challenging activities.
A fun build-and-play experience As you construct each robotic toy using the step-by-step building instructions in the app, you’ll complete a series of fun coding activities along the way. But if you prefer, you can also download a PDF version.
Coding, the fun way If you’ve ever used a visual coding environment, you’ll be right at home with the Robot Inventor App’s colourful drag-and-drop canvas based on Scratch. Each coding element is grouped into categories so you can quickly find what you’re looking for. As well as using the coding canvas to complete the 50+ activities included in the app, you can also code your own activities for an even greater challenge – or, if you’re a more advanced coder, you can also use Python.
Take control The Robot Inventor App includes a remote-control feature so you can get your robot walking, dancing and firing with just a few taps! You can also customise it to create your own personalised controller.
Learn while you play While you’re building, coding and playing with your robots, you’ll also be exploring, experimenting and learning.
Advanced machine learning Using your device’s camera or microphone, you can train your models to recognise and react to objects and sounds… even your own voice!
A community of fan models The Community section of the app lets you build and code a growing collection of fun models submitted by some of our fans.
Share your cool creation If you’ve designed and built your own amazing robot, you can take a photo of it and upload it to LEGO Life for everyone to see. You can also get loads more inspiration from what others have created.
Key Features: Intuitive drag-and-drop coding interface based on Scratch 50+ fun and challenging activities for beginners and more advanced users Machine learning with advanced object and sound recognition Community section with fan models and inspiration Hub to hub connection for extended play possibilities Help Centre with lots of tips for learning and exploring Text-based Python coding for more advanced users Bluetooth connectivity for wireless communication Remote control for instant action Consistent experience across iOS, macOS, Android and Windows Digital building instructions included in the app Kids gain STEM skills through playful learning

Comments on LEGO® MINDSTORMS® Inventor for Android

It was great! I made some programs, but most of my blocks are drafts. One thing though. Can you add more blocks like Do this unless <> Code here that triggers if boolean is false Else Code here that triggers if boolean is ture

I have an important question. I have heard that lego windstorms has been discontinued, and the app will stop updating, but I'm wondering if the app itself will still work and be available or will it completely disappear from my phone after 2024, will my inventor set become useless after that? Will it still work but not be updated? It would be very helpful to know what is going to happen with the app and if my lego set will become useless like my wallet looking at spike prime pices.

Really easy to code. Scratch Programming Blocks makes it easier to program as many kinds da are familiar. Been using this app for a year and no problems! However, the community tab is not like its name. I would much rather have the tab to be able to share videos of self created robots. To prevent unnecessary videos, maybe implement an Admin Check

This is the one of the best windstorm apps I have ever seen
★★★★☆Sirisha Karkera· Jul 13, 2023
The Windstorms hub is asking for an os update I follow the steps and when I try to connect the hub it takes my back to the os hub update what do I do

Please make the app available on Chromebooks. Other Android apps including the EV3 app are working but not this one. My son has a 51515 and can't use his Chromebook to play and learn. Update: The answer makes no sense. There's no such thing as Android version in Play Store. Android is the operating system and is version 9 in my sons Chromebook. But this has nothing to do with Android version. The app needs to be enabled for Chromebooks.

Every time when trying to connect app with windstorm via Bluetooth, the app closes.

We've been trying the LEGO Spikes recently. We've been going for a week and have had several technical problems. The hub has trouble connecting. Some devices have more features than others, and we've had anywhere from 0–2 updates per hub, per device, per day (no they do not add the missing features), these updates can take most class; sometimes these updates will finish up completely before giving an error and restaring. I don't know the root cause, but I hope the Spikes can be used in class.
