LEGO Technic 42158 NASA Mars Rover Perseverance detailed building review 

Probably the perfect Technic set! The real rover will also not go over a big rock but rather around it. Suspension is mostly for the uneven terrain. Would have been a cool Easter-egg to add the pet rock that Perseverance carried around it's wheel for a while. I guess you can use one of the spare parts for that. ;)

The suspensions doesn't work when the set is pushed, because it reality all wheels are powered, which cooperates with this kind of suspension Pushing it makes it less stable because forces are acting in reverse (pushing wheel over surface vs pulling surface under wheel) This kind of suspension can climb over obstacles up to three times of wheel diameter (Imagine you car going over curb three times the wheel diamater). That's also one of the reasons why the rover is so slow

Hi Balázs! I think this set is better than the LEGO Technic fan community thought because it contains a tons of brilliant building techniques and also rocketed from the not so interesting licensed car,construction maschine category which is great and makes this set more desireable than other sets. Sorry for the minimal grammar mistakes but I still learn English and do my best. Nice content,thank you to shared it this! 😊

This is probably the first time that the Technic style actually fits the build.

I really love this set already, I cannot wait until someone in the community find a way to motorize it. As a NASA fan - I need this!

My theory about the orange flower piece (3:53) is that it's supposed to resemble the California Poppy, the state flower of California, where the rover was built and tested.

The designers of Technic sets are beyond amazing. So many varies of techniques in each set they produce

I wish lego mindstorm was still a thing. God mindstorm was so ahead of its time.

Very excited for this set. It’s very unique for the line and isn’t another supercar or construction vehicle. The steering is genius even if there is slack in the functionality.

Thanks for the shoutout!

i personally know a lot of NASA offices that will definitely have one of these.

Thank you for another thoughtful and enjoyable review - this is gorgeous and I'm really looking forward to getting it and building it!

This is a very cool set. A definite buy … Keep up the great videos

You should tell Lego they owe you commission because you just sold me this set! Not just one either, but rather one for me, one for my daughter, one for my science-ie friend, and maybe one for storage because in 10 years it’ll be worth $750 in the sellers market! Yes sir you just made a sale for Lego Corporation. I hope they appreciate the value you provide for them and their customers! I sure value your videos! Thank you for reviewing and sharing with RU-vid! 👏👏👏

Didn't know this was being released! It looks fantastic I've been interested in the whole perseverance mission from start, part. The helicopter. I'll be getting it, especially the price looks good

I neeeedddd itttt nowwwwww

I work at cornell. I see one of the real rovers every day. They made a few so when things go wrong the support teams on earth could use the other ones to help fix it and send commands. Even though I see the real one all the time I might have to get this.

Great review, obviously but super kudos for including all the technical detail about the rover itself. As someone who's had the chance to work with the rover teams, it was nice to have that extra detail shown off!

In defense of the suspension action: I think the LEGO design went in the direction of more realism than play. Moving the model by the body is a poor simulation of the design. Because the rover is driven by the wheels they will climb obstacles. The suspension does not need to bound over uneven surfaces like an off-road vehicle. It will never coast - it is always driven - slowly. The suspension needs to move to maintain stability and contact with the surface as the wheels follow the undulations - not react to them.

Ooh, this looks nice! I'm undecided about the new skidder because of the price, but this one I will definitely grab!

My wallet after watching this, just after I build the Discovery set last week: "Oh sh... here we go again"

I had the pleasure of building this recently and I've got to say I highly recommend it to whoever can get it.

Thanks for letting me know this will not be available until August.

Man I like it. That will be a nice add to the shuttle and Saturn. It has some nice functions and features. The cost is reasonable. The down side, I have to wait till August ☹️, yes I'm in America. As always, your builds and opinions are greatly appreciated.

Im looking forward to somone motorizing it, that mechanism is brilliant

Very cool set. Also one of the hardest sets I've made, had to take it apart and rebuild it a couple times to get the mechanisms just right.

Thanks for the detailed explanation on how the steering mechanism works! It's really genious, such a shame the rest of the system has so much slack in it!

This is an awesome build. thank you for the video. Waiting (im)patiently for June 1st.

YYESSS!! Been waiting for your review of this set! You're the best Balazs!

...does have ingenious building tech'nics 😋👍🏼...

I've been waiting for this>:)

First day buy for me. This will Be my first set of 2023.

Definitely excited for this set to arrive it looks amazing

This is amazing I need it

Just got a polybag version of this. Fantastic!

And the next video is gonna be I WOKE UP IN A NEW BUGATTI (i meant the Bolide)

Just built it , it really is a great kit!!!

It looks great! Yeah, the suspension will never work great but that's because it's designed for Mars gravity 😎

Not that bad. I think this set gets a lot of attention by the space and mars fans. And in some years it will get precious. My guess. 😊

This is cool. I bought Curiosity and never opened the box as it was so cool. I might do the same with this. As much as i love the models, some boxes are too nice to open sometimes!

Wow, they are all top secret stuff, worth getting one.

Grats on being first in my list for the review. Just saying how much i love the content you put in reviews, all of it is great info and enjoyable details. Looking forward to this set, definitely more interesting than the lunar lander.

Snap this is so nice & kind of serene i could possibly get this for myself i like how unique this is :)

I love how the 42158 has so many gears and functions! (yes i liked my own comment)

Such a set should really be able to drive over some obstacles I think.

Supercool build and set.. Will have to get this one!

I bought that set. Building process is pleasant and model itself is nice, but in my opinion there is way to much slack in steering mechanism. I wonder if pneumatics wouldn't be a better design choice.

someone’s gotta make a sky crane that can attach to that thing!

I can't wait to get this set. Iove the NASA sets and already Space Shuttle Discovery, International Space Station, the Apollo 11 Rocket and the Apollo 11 Lunar Lander and i think this will look great with them :)

I like the set quite much

Thank you ! It is Augustc2024 here j. MID-Amerucz and I've just purchased my LEGO MARS ROVER. Your comments should prove helpful. I will say that I have an ambitious UPGRADE even before I open the box. I intend to use high torque RC steering servos, a 5 chanbrl 2.4 GHz reciever, sensor-equipped brushless drive motors, LiPo compatible ESCs, rea, fully functioning sensors fir real-world data collection, full duplex FPV and data streaming on 5.8 GBz. I might use digi-vid cams. and gyroscopic stabilization . The challenge will be to micro-miniaturize real spectrometers and a possible surface scaning Fourier Transform analyzer. The task is way large. but might keep me COMPLETELY (IN)SANE this coming Winter 🤪😵‍💫😬 Seeing that I have a PRUSA 3D printer, some of my "bricks" might be a tad off the wall.

Wonderful review ! Please show us how to motorise this set. I will buy it as soon as the price is at 60€.

Well price to function ratio

Thanx for the video.❤❤❤

I just built this set, it will look great next to the ISS.

omg it is so cool i can now flex on others

I NEED THIS

I really like this Technic set. It’s my favorite LEGO theme ever, but I know almost nothing about this Mars Rover itself

Great review!

Why the small flower to block the mechanism you asked. Well, a normal stud would be knocked off a lot easier than that flower stud. It has a bit more clutch power and by its shape it dampens the force of the mechanism that hits it a lot better. So small but clever design.

Impressive

The flower and carrot may be in reference to the mission to look for signs of life. In the same way as the Jurassic Park T-Rex they might have snuck in a frog. The real Perseverance does carry a dinosaur.

It would be interestiIt would be interesting to see one compared to the old Mars Exploration Rover set 7471ng to see one compared to the old Mars Exploration Rover set 7471

i am nasa red fan ❤❤❤

I know what I’m getting my dad for Christmas or his birthday

2:58 that thing is a rtg (radioisotope thermal generator) it’s what gives the rover its power Edit: I didn’t see that he explained what it is later in the video.

compare the creator 10266 instruction manual to the Percy manual. quite a difference and an indication as to what could have been included at a minimum. it was impressive in many ways, and an enjoyable build, but is ultimately just a display item- which was a disappointment. found it fairly complex for children who seem to be the target market for it especially with the AR which could have been far more exciting considering the engineering behind the rover. missing the sample return entirely, and it has far too much slack in the steering. could have been a truly exciting motorized set. would have been immediately worth a few hundred more if it was more feature rich in that way.

I was sad I missed out on the Curiosity Rover (set # 21104), but looking at the pictures, this one is a much better set.

Interesting how your gear ratio in your ingenuity helicopter is 1:10. In mine it’s more like 1:4.

I think they should instead of doing info about the rover in the instructions, it should have a QR code and it should show you the different featuresof the rover irl and show them on the build.

well compared to the ideas curiosity this is quite large so I wouldn't call it small

I don’t think the propellers are linked with hearing. I think when you spin the top one you create air movement which spins the bottom one.

It is a steal for just $99

great video my friend :)

yes!!!!

Once I found a missing piece in the plastic bag after a year when I was sorting my LEGO boxes 😅

So about the wheels, something I noticed while building the set is that the instructions tell you to misalign some of the universal joints along the drive shaft, which was very odd to see. I thought maybe it made the steering smoother to have them misaligned (something about the alignment of the wheels relative to the axis of rotation?) but it doesn't seem to me like there's anything in the instrutions about it...

dam thought this was like a Rc car

i wish it was motorised.

A B model would have been very easy here with Curiosity.

I’m never this early

looks awfull geek in me its beautifull

I wonder how long it will take for someone to make a motorised version.

What are dimensions of the ready and assembled position of the rover in inches

That's about 450 bucks in my country

Already available in France 👍🏻

August August !!!! WTF!!!! For the country that actually produces the real Rover we should begin also. I was dead set on ordering this on June 1st

2:57 its an RTG

So… Has the app been updated after 2 months or is it still unusable?

Wonder what will motorised version like

Right at the beginning it's unclear what to do. There are TWO parts bags with the number "1" on them. Which one am I supposed to open?

Well good for them for trying to be different, but i dont really like it

Jeez... I mean the blue and red pins and yellow axles are ugly in normal Technic sets already but this... Before buying this, one should get a bunch of white, black and grey pins from 3rd party suppliers to replace the original ones.

Is it RC?😊

I'm disappointed that the wheels are a single piece of plastic and not something you assemble

Btw guys it’s sold out lol

hi

Early

Way to many colored pins 🤮

Im no aerospace engineer, but NASA really designed the ugliest little rover. Functional yet hideous.
