LEGO - MINDSTORMS® Robot Inventor 51515

We are so sad this kit is no longer available. We have one for my 10 year old son and he has spent endless hours building, rebuilding, & creating his own designs. We were really hoping to get him another kit as he has so many build plans.

I mean it's even a technic set and literally everybody knows there's nothing wrong with them

Great product it. I used it to program some of my collections, so I can control it for my phone. Wish it came with a large motor for my bigger stuff

[This review was collected as part of a promotion.] I think this might be the best LEGO set ever made. It's got the 4 motors sensors and lots of pieces. I've made gearboxes, cars, clocks, a radar and even a code that makes an essentially learning vehicle. The builds on the app are great but if you've got the mind you could make so many things that even the ev3 with multiple hubs couldn't do. I don't see why people complain about this compared to ev3. This is far superior. The one issue I have is that the motors aren't very strong and they stop with small amounts of force. But with 4 motors most of the time the issue comes up a have a second and maybe even third motor that I could put on there to increase the strength. I have seen multiple people who have made balancing vehicles with this. Absolutely amazing set well worth buying for anyone who likes STEM

LEGO added move models to build during the last update. More features are also being added with each sw upgrade! Amazing
