An American YouTuber has succeeded in creating a robot likely to enter the Guinness Book of Records by putting over 100,000 dominoes in 24 hours. For this feat, he chose to recreate an image of the famous game Super Mario Bros.

[EN VIDÉO] Record: this robot finishes a Rubik’s Cube in less than a second A robot has just set a new record for the resolution of a Rubik’s Cube: 637 milliseconds! The previous record from the start of 2016 was 900 milliseconds. The fastest human in the Rubik’s Cube looks like a lambin with his 4.9 seconds!
A robot has just established a new world record by placing exactly 102,600 dominoes in just over 24 hours to create an image of the game Super Mario Bros. This is the culmination of a five-year project. Baptized The Dominator, the robot was created by Mark Rober, youtubeur and former engineer of the Nasa, helped by two students from Stanford University and a software engineer.
The system is made up of two distinct parts. First of all, a robot on wheels that places the dominoes on the ground. It carries a plate made up of 300 funnels 3d printed, which place the dominoes very precisely. The system is closed below by a simple grid. Once placed on the ground, the grid is offset allowing the dominoes to pass. The robot moves thanks to a pre-programmed route, a GPS system and markers on the ground.

Sorting dominoes by a robotic arm
The other half of the device is a loading area. From treadmills bring dominoes from each color, and one Kuka robotic arm place the dominoes individually in a second assembly of 300 funnels. The first robot positions its own funnels underneath to receive a new load, thus preventing it from waiting between two domino placements.
The Dominator is extremely fast, since he managed to do in 24 hours what would have taken a week with a team of seven experienced people. However, it has limitations since it can only place dominoes in straight lines, and cannot connect them or make more complex assemblies. They had to run some green pipes from Super Mario Bros along the entire length in order to drop all the rows. This project is no less impressive, and may well encourage some to embark on engineering studies.
