Robot Inventor set 51515 vs. EV3: review and first build
In this video, we look at all the hot new stuff in the MINDSTORMS 51515 Robot Inventor set. It has many improvements over EV3. Find out here what the differences are between EV3 and the new 51515 Robot Inventor set.
I guess people will be calling this LEGO set 'teal MINDSTORMS' or 'MINDSTORMS 5' or 'MINDSTORMS 515', which is short for the set code. Part of my review is to try and build a little car without any instructions. This experiment will give us a feel for the increased speed of building with the new set. Let's have a look!
Like all LEGO boxes, the set number, set name, and suggested age is here in the top left. It is a 10+ set. EV3 had no age marking on the box. My experience is that the age group is the same. I have organized fun First Lego League build sessions using EV3 with 10-year-old kids. The graphics are very different from LEGO technic and the previous MINDSTORMS. The black and bright colors give the set a bit of an 80's retro-cool look. Sizewise, the box is the same as your good old EV3 box. The packaging shows that it's compatible with Mac, PC, Android, and iOS. LEGO really went out of their way to develop and support all these platforms.
As you've seen in all of the previews, the new MINDSTORMS hub is basically a green SPIKE Prime hub. This means we get a built-in gyro and accelerometer. With the internal six-axis inertial motion unit, you can sense the orientation of the hub. It can also detect taps. You can also read out its rotational speed over 3 axes.
Especially for walking robots, this will be great. I remember struggling a lot to get my blue dragon walking because everything was so heavy. Unlike the EV3 hub, this hub has a built-in battery! Yay! No more tedious charging of AA cells. It also has pinholes on ALL sides. Not just bottom, left, and right.
Compared to EV3, these motors are way smaller, lighter, and more comfortable to build with. I guess they will have less torque, but this won't be a problem since your robots will be much lighter. And you get no less than FOUR of them. This is really awesome. I remember that with EV3, one of the first things I bought was another motor.
You will recognize the sensors from the SPIKE Prime set. There is no force sensor, but we do get an ultrasonic and a color sensor. I don't expect I'll ever miss the force sensor. Like SPIKE, these new motors have an internal absolute positioning system. With EV3, I used the force sensor mostly for calibrating motor positions. If you want to make your robot interactive with buttons, remember that you can use a motor as a button. You can also tap the hub because there's an accelerometer inside.
I remember running out of 5 x 7 frames often when building with EV3. This was so frustrating that I bought the bucket wheel excavator. The reason? There was a HUGE amount of frames in that set. It seems that LEGO has listened to people like me. They have included way more 5 x7 frames. Not only that, that set also has the new 7 x 11 frames and the 11 x 15 frames. I like frames because you can build so quickly with them. They are pretty rigid and take parts from almost all sides.
This set has Ninjago missile launchers. I guess proper robots should have guns? This part can do nothing but shoot. Maybe the missiles could function as a pair of legs for a walking robot.
This box includes no less than six wheels! Mars rovers are now within your reach.
