Features & Capabilities

Create intelligent remote-control robots and vehicles using interactive in-app building instructions with the LEGO® MINDSTORMS® Robot Inventor App. For 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 with the step-by-step building instructions in the app, you’ll complete a series of coding activities along the way. Drag-and-drop Scratch-based coding is intuitive, with Python available for advanced users, and Bluetooth remote control for instant action. The app also features a Machine Learning module for object and sound recognition, a Community hub for fan models, a photo-sharing option to LEGO Life, and digital building instructions included for easy reference. The experience is consistent across iOS and macOS and includes a Help Centre with tips for learning and exploring.

User Reviews

Overall, users praise LEGO Mindstorms Inventor as a fun, educational tool with Python coding support and strong project potential. However, recurrent issues detract from the experience: connectivity problems with Bluetooth/hubs (notably Spike Prime), poor backward compatibility with EV3/NXT, and general instability with lag or freezes. Hub updates sometimes break connections, and some users seek better documentation and smoother block-coding performance. When it functions, the app offers solid classroom value and engaging robotics activities, but reliability and compatibility are the main concerns across reviews.

Pros

Fun and engaging to build and program LEGO Mindstorms robots.
Allows coding in Python within the app.
Strong classroom and educational potential for teaching robotics and coding.
Generally positive sentiment when it connects and works as intended.

Cons

Frequent connectivity issues with Bluetooth/hub (especially Spike Prime) and iPads/iPhones.
Limited or problematic backward compatibility with EV3/NXT hardware.
App instability, lag, and occasional freezing affecting usability.
Hub updates can disrupt connections or require additional fixes.”],

This app, and the 51515 set are both great. My 51515 set is second hand, but it’s high quality made it look as good as new. The app, however is kinda weird. I can’t put my stuff on the community section, and tricky’s basketball launcher is wired when you attach it to tricky, and one step of Charlie’s drum set is also wired. All in all, this gets 4.8⭐️s.
