5 Reasons Why the New LEGO Mindstorms 51515 is better than EV3

There are many unseen advantages to the LEGO Mindstorms 51515 that the EV3 system lacks! A lot of fans question the practicality of the new system though, and aren't excited to upgrade to the new system. I want to bring out the positives of the new system more!

My humanoid robot featured in this video is named "Beta Rex" Building instructions and program can be found in my latest video!

I understand your Reasons! Personally I just like the EV3 because it has more options with cables, screen, more sensors etc. But after watching this video I'm liking the 51515 more than first! Great!

I like how the EV3 is just standing there looking at this dude ruining his reputation 😂

I remember how happy I used to be when I used the NXT 2.0 software to make my face appear on the screen when I was a child

The EV3 is a full fledged computer.
I can run Debian on it (without modifing anything or breaking warranty, it's as easy as pluging in an sd card) and use any programming language what so ever: C, C++, Python, Java, etc.
I can run a web server on it and host a web application to control it from a smartphone or computer browser without installing any other software on them.
And it has a USB host port to which one can connect every sort of device (Wi-Fi dongles to connect to access points and the internet or host an access point, webcams to see what you are doing, flash drives, ethernet dongles, arduino boards, other older mindstorm bricks, etc).
One can even connect to the USB port a WeDo usb hub and use any Power Function device through it.

You know that the screen on the ev3 brick is a MONOCHROME LCD, right?

I have a question if I buy a lego ev3 will it still be compatible with the sensors and motors of lego ev4? if i want to buy some in the future

Just when I needed these questions answered! Cheers!

I agree on multible topics, like the formfactor, compatibitity and the load-cell-module and the absolute encoder motors are indeed amazing.
But:
My first thought was "Oh holy shit, I miss a real display!" The dot matrix the new system has, is just not having enough possibilities and functions. It´s more a playing feature than a usable function.
Losing Daisy-chaining is also a HUGE setback and will piss off many experienced Mindstorm fans.
And also the name gives me a headache: EV3 was a short and simple name. Let´s just call it EV4 ! ! !

These are all great points, especially point #2, the absolute positioning motors are great and incredibly accurate. I did an experiment, doing 100 rotations of a motor and it always returned to the 0 position when commanded.

I think you left out a MAJOR improvement though, the onboard accelerometer and gyros on the new Hub. This is a MASSIVE improvement and frees up art least one sensor port on those EV3 designs that use a gyro and this gyro and accelerometer is MUCH better than the EV3 gyro sensor.

I also like the lightweight and size of the new hub, it is almost shocking how light and small it is.

I also like the software that comes with the 51515 set much better and since I have been working with micro-python on various micro-controllers since nearly the beginning of micro-python I LOVE the micro-python implementation on the hub. In fact the HUB is based on the STM32F413 microcontroller which has excellent micro-python support.

I do like the screen on the EV3 a bit better, I am not a fan of the 5X5 LED display. I would have rather have had a small, color touch screen LCD.

Right now though, I still like the EV3 a tiny bit better. With more time using it, and updates from Lego and the community the new hub will probably surpass it in my mind.

One problem that I've looked into and there's (from what I've found) really no way to extend the cable for larger builds. It was an easy fix with EV3/NXT because you had swappable cables, inventor just has the cables connected directly and you can't change em. Wish they included like an extension cable that would take the old cable and add more length to it but I'm not Lego so I can't change that.

Great video! Quick question about the ultrasonic sensor in 51515. I just built Tricky, and the Ultrasonic sensor seems a little sketchy. Most of the time, it measures correctly when things are close, but then I see momentary readings where it says something is 200cm when it’s definitely not 200cm away. Also, anything over 150cm distance registers 200cm (e.g., if something it’s 152cm away, the sensor says it’s 200cm away). I did this test on a flat wall with the sensor pointed perpendicular to it. Did you have same issues?

Do you think it's worth it to get the Spike Prime Expansion set to use with 51515? Also, how do you know there's going to be daisy-chaining in the future.

Thanks!

Thinking of grabbing one but what if cables will die? How to replace them? Or is will be possible to get replacement parts separately?

[jan]

Hey,
where I can get news for the new mindstorms set?
Like when daisy chaining is available or something like that?
Didn't find anything on the web :(

[legotechnicmastery]

I just discovered your channel today, and already watched dozens of your videos 😄 They really inspire me to make videos again! I've always felt like the social dimension was lacking in Lego Technic videos, people often getting shy in front of the camera perhaps ;) Nice to see a face!

The powered up capability is why I love the new MINDSTORMS. My last MOC was a robot inventor/control+ hybrid thanks to this.

Hi, @Unbrickme . I have a question: is it possible to use real clock time (eg 20:21) hh:mm in the script code on the new hub? I need to trigger functions based on the actual time of the day, and the code should run continuously for my automation project.
I dont have lego Mindstorms yet amd need to determine if it has the capability which i need.

[imaginationsquare]

I allready have lego boost and I was wondering if the boos motor is compatible cuz it has the same type wire.

[thatnicklongo]

So if I'm using Lego mindstorms to build a foundation for an android of my own design, should i use the inventors kit because Blast has better mobility? What advantages does Everstorm have over Blast if I'm using one of them to make an android?

I wasn’t going to buy this MINDSTORMS system, but I ended up getting the 51515 plus the LEGO
Education Prime and Expansion sets. I have 2 of the EV3 Education Core sets and 4 Expansion sets along with the 31313 set. I also own the Rcx 1.0, 1.5, and 2.0 sets and a couple of the NXT sets.
