    A Great Upgrade, but also a downgrade
    I would recommend this to a friend!
    Purchased for: Self
    Overall, I really love this set! You get the amazing new Large Technic Hub, which is perfectly compatible with the powered up motors. Instead of having to use the large bulky motors as with previous motors, you can simply use the much smaller and better powered up motors! Which is awesome! The new mindstorms motors are also pretty awesome, since they come equipped with absolute positioning. This is perfect for synchronizing walkers, and you don't have to use touch sensors to synchronize motors as with previous models, like the NXT 2.0. Absolute positioning motors are absolutely a game changer! I also do really like the new hub! It's much smaller than any of the previous intelligent bricks we got. I like the Tetris style screen a lot, it's very clean, minimalistic, and futuristic. And most of all, because this screen is so unique, it will not feel outdated at all in seven years (I'm looking at you EV3). I love every single one of the five robots, they each have a unique feature of some sort, and they're all amazing. Coding with scratch 3.0 is pretty cool, and a nice stepping stone into more advanced coding. My favorite feature is the ability to natively code with python out of the box. I also really appreciate that the mindstorms software comes equipped with the most common commands you need for python, making it easy to learn even for beginners! So what's the downgrade? For one, as of right now, daisy chaining is not supported. I have checked the specs of the new large technic hub, and it seems to be able to support daisy chaining, it's just the software that needs to be updated. Two, the lack of a converter cable from the previous NXT cable to the new powered up cable means that all the previous sensors and all the third party sensors made for the NXT and EV3 are no longer compatible with the new system. Three, Data logging is still possible, but it must be done on the app while the hub is connected to your computer or mobile device. You cannot do data logging on the hub itself. Four, the removal of the test pad. The test pad in lego mindstorms sets has been around since the days of the RCX. It was one of the best aspects of LEGO mindstorms. One of the activities for the robot tricky required him to follow a line. Many people don't have colored tape to simply make a line on their own. I had to use the older test pad from my NXT 2.0 for this activity. Overall, I love pretty much every aspect of this set other than not being able to use daisy chaining. LEGO, please make a software update fast so that daisy chaining is supported.

    Good set, fun to play around with kids, limited.

    This is a strong set to teach the kids programming. It has a very easy learning curve, but allows you to make it as complex as you want in the end. The flexibility is awesome, enough motors and sensors to make anything you want. The biggest miss is to allow connection to other mindstorm bricks. The old EV sets would allow this, creating limitless possibilities and complexities. WIth this new set you're limited to one mindstorms brick, with 6 ports, and no communication whatsoever. I do hope this will be added as bluetooth functionality in future software/firmware updates. Yes I would recommend, but not to replace existing EV3 sets.

    No Daisy Chaining
    | 25-34
    Purchased for: Son
    I’ve always been pretty interested in robotics. I remember playing with lego ever since I was a kid. When the ev3 came out, I was in my early 20s; I thought it was really awesome how you could create robots with lego and daisy chain up to 4 ev3 computers to make some incredible robots. I used to create some really cool robots in my spare time. I purchased the new robot inventor set for my 7 year old son, since I wanted him to have an interest in robotics like me. I was pretty frustrated when I found out there’s no way to daisy chain the new robot inventor system with other robot inventor computers. You’re limited to just 6 ports, and you cannot build bigger and better robots. I simply do not understand why the new system removed the daisy chaining functionality. The new system is pretty much worse than my older ev3.

    Good kit, but a little disappointing
    | 45-54
    I would recommend this to a friend!

    I bought the kit to get back into Lego robotics tinkering, and it's an okay kit, but it contains no touch sensors. for the price it would have been nice had Lego added a touch sensor or two. If Lego didn't plan on including a touch sensor it would be nice if they offered them for individual sale. It would also be nice if it had a similar array of components for individual part sale like servo motors and such like they had for EV3. As for recommending the kit... I would, but with reservations about the sensors and lack of additional components that make robotics interesting.
