LEGO Mindstorms Robot Inventor 51515 Set In-Depth Review

The LEGO Mindstorms Robot Inventor 51515 is the next generation of LEGO robotics. Some fans question if this new system is actually better, or worse in some cases than the ev3. However, I really think that the positives outweigh the negatives.

Important: The programming app is the same across ALL platforms, so the tablet interface, which I show most commonly, is the same as the computer one. Powered up motors are completely compatible with this new robotics system, more on this in the datalogging section.

I'm using this video for a drinking game. Every time I hear "really" everyone takes a sip of beer and when it's "really, really" a shot of Rakija. Great review ;)

[richardbrobeck]

One the big issues I see with the new design is that thin wire that connects the motors and sensors to the brick as a weak point as a teacher we use the EV3 mindstorm kits in the classroom and they see a lot physical abuse .

[TinkeringJohn]

I noticed for Charlie, whenever they show you how to build the bent beams with the colored beams to use on his color sensor, the inset showing what it looks like when completed is missing a blue and yellow beam3.

[Chuckiele]

I can understand why people see the tetris style display as a downgrade from an actual screen but I think it will age much better than the previous models because its a timeless design. No matter how modern and expensive its hardware was, it would be outdated in a couple of years because technology just advances too quickly. Reducing it to the bare minimum and instead using your phone as an interface however will make it stay up-to-date for a much longer time. I think it was a great decision.

Very informative and thorough review, with really good points. Well done!

[mariovelez]

I really want a camera sensor for the robot so I can do some facial recognition and image processing with machine learning that would be really cool

[JKVeganAbroad]

An amazing review! I bought this as a gift, and I’m going to give them a link to this video when they open it!

I love how they cannons to shoot with, its amazing. Great reviews also 👌I under estimated Charlie. That one is the best, the drumstick feature is amazing 👏

[odinbrousseau]

You are insightful. I purchased my first lego kit 51515 couple of days ago to teach my kids some robotics. Thanks for the reviews, the 51515 kit is powerfull.

[Telefiend]

Definitely want one of these sets now, and totally subscribed

[thomasl.]

Wow, the best and most detailed review I have ever seen for this set! Thanks for all the details!!!!

The FIRST Lego Robotics Invention System (yellow RCX) is so popular because it is very easy for kids to build a robot. It uses studded bricks which are so children-friendly.
It even can be combined with LEGO City models children already had in their home for many fun projects.
I remembered my students build sumo robots with laughters and big smile in their face.
After LEGO change it into more Technic in 2006 and named it 'Mindstorms', children not having the same easiness as before. It operates better and better for each new releases, yes of course.
But less fun and not as easy as the first.

Fischertechnik has had encoder motors with absolute positions for years. And fischertechnik also have a little camera for their robots which is also very cool. I'm sad that mindstorms haven't a camera for his robots bc that would make a really cool add on.

[zzaqd]

I got one of these for Christmas, it is 300% cool, especially coming from the NXT, which I already thought was really good. Absolute positioning is where this has the big upper edge.

[nitishakhan]

I got the new LEGO mindstorms three days ago and after watching this video I know how it is! Thanks for the video! 😁😁😁😁

[VictorMistral]

I had a diffenrial bot with the RCX, and pretty sure it wasn't custom...

[xylasophinos]

You had me at “absolute positioning”! Sounds like a great upgrade from my old nxt! Those motors are so inaccurate, especially after several years of use. Thanks for the great review!

[imthefunnyone]

I use the the hub to make mocs. I use the angle of the motor to my advantage when making a steering system.
