LEGO MINDSTORMS 51515 Robot Inventor app now available to download

The app for the newest generation of LEGO MINDSTORMS, 51515 Robot Inventor, is now available to download.

The coding set is still six days away from release, but eager fans can already grab the corresponding app ahead of time. Promobricks reports that version 1.0.0 is currently available on iOS, Android, FireOS, macOS and Windows.

Given the advanced nature of the software, the app may not work with all smartphones. You can check compatibility over at, but the LEGO Group recommends simply attempting to download the app.

If you can do so successfully, then chances are good that your device will work with both the app and set. If you can’t see the app in your device’s app store, though, then you’re probably out of luck. As a general baseline, says the app requires iOS 13 or Android 7.0, or newer.

The official companion app will allow fans to interact with 51515 Robot Inventor when it launches on October 15. Along with building instructions for each of the five models, the digital experience will give you full control over their programming. You can opt for a BOOST-like drag-and-drop interface based on Scratch, or text-based programming with Python, if you know what you’re doing.

51515 Robot Inventor will be priced at £329.99 in the UK and $359.99 in the US.

I like to think of myself as a journalist first, LEGO fan second, but we all know that’s not really the case. Journalism does run through my veins, though, like some kind of weird literary blood – the sort that will no doubt one day lead to a stress-induced heart malfunction. It’s like smoking, only worse. Thankfully, I get to write about LEGO until then. You can follow me on Twitter at @brfa_chris.
