Lego Ideas – Curiosity Mars Rover (21104) Review


Lego Ideas – Curiosity Mars Rover (21104): I considered briefly trying to see what of this I could source myself, but despite a rare price tag I bought the full set via eBay and I’m glad it did. (Guy even gave me a little ‘Martian’) This is something I wish Lego simply did more of. I honestly have no idea why there isn’t an ongoing NASA line (I mean my wallet is happier), but it feels like a perfect match beyond just the Lego Ideas’ program, and a Discovery channel promo. It not only makes kids excited about space (I mean just imagine a kid building the ISS set because their dad is actually planning to watch for it in the night sky later), but adults who love science get awesome set pieces.

What Else? Normally while there are a few things I could do about Mars (distance, how well this would hold up in the Martian gravity and wind, etc.) However I think it’s more important to fully underscore how insane the reality of this model is. Because while this looks fantastic – a real life Volkswagen size robot of this model really landed on Mars. I know that may seem blase now, but the actual mechanics of this still haunt me, and they should you as well:


Remix: So for this set I managed to get everything used, and I’m actually pleased despite some setbacks. With the weird mechanism for movement I wanted to see if I could translate that to a rube-goldberg machine where it would move along the wheels. Sadly I would have needed a few extra parts so while this has the spirit of my remix idea it is more of a complex slide than a true rube-goldberg machine.


Here’s a gif of it working:

Final Thoughts: I honestly am debating building myself a bonzai zen garden, but to slightly dye the sand and just plop this little guy inside it. For now he’ll hang out with Wall-E, but this is one of those few sets that I am just glad exists in this world.

Final Score: 5 out of 5 Stars
