Review: El mejor kit de robotica que ha lanzado lego, a mi hija le encantó, viene con 5 modelos por defecto pero contiene actividades extras como el modelo pet gelo de la comunidad de fans de lego, ademas de muchos modelos que puedes encontrar en internet.
Review: This is the first Lego kit I bought that didn't come with paper instructions. Instead I used the Mindstorms app to build and program the robots. Pretty interesting. So far I only built the buggy and that was fun putting it together. I wish the kit came with a play mat with lines for line following. The kit comes with 4 motors and 2 sensors. I hope that Lego will make It were I can buy sensors separately like they did with older kits. I haven't test to see if using the python programing can make the robot kit connect to a Raspberry pi, but that works it would be cool.

*by M***D on 29 June 2022*

Bought this with my 8 year old son. Seems like an expensive piece of kit but the level of ingenuity and technology that this kit holds is absolutely priceless. Gives him the ability to build all sorts of different robots and then PROGRAM THEM TO DO STUFF!!! Like, seriously!?! This is college level programming for kids! Unreal how they’ve made this product and made it so easy to use for young kids! Can’t say enough about it. Mind blown. Hours and hours of fun so far with no end in sight. Want his friends to get the kit too so they can do battle:P
