LEGO House of Cards - SPIKE Prime

A LEGO machine capable of building house of cards.
After a long time without personal projects I decided to revisit an old concept that I made for a client that didn´t became reality.
It always a challenge to create machines that will interact with other objects, and in this case, the challenge is a little bigger because the objects are playing cards and the goal is to stack them into a house.
To be able to solve this, I ran through several small hypothesis and many prototypes. For me, LEGO is one of the most powerful prototyping tool because I can easily built different solutions and test them in a small period of time.
Some of the challenges:
Choosing the deck of cards
Cards feeder
Cards grabber
Model Stability
Communication between Hubs
The hole process took more than 200h, divided in several nights and weekends for 5 months. I am happy with the final result and I am not planning to do any new version of the LEGO House of Cards machine.

It looks like a tall colliseum

[@arthursacek]

It was the goal. But after calculating the amount of cards needed to build the full coliseum I decided to build just a curved wall.
