You’ve probably heard about NASA inventions, which help colonize and discover Mars. However, have you ever seen the same machines, but made of Lego’s details? Let’s look at them!
First, try a flight of construction with a propeller, but without a powerful engine, isn’t it fantastic? Unfortunately, yes. Although the propeller works, it’s still cool.
The next construction moves on 6 wheels and has on its “face” something that reminds me of a smile. In my view, it seems so incredible, but the machine couldn’t overcome the barrier.
If we change tires? They’re bigger, made of gum, not plastic, and still can not overcome the heel.
It is so lucky that engineers have the third variant - the track. And, HALLELUIA, IT WORKED!
I think engineers, members of the NASA team also always look for the perfect variant and have so many tries. And because of their efforts, we can discover more than just our planet.
