For Rubik's Cube lovers around the world, how to restore Rubik's Cube in the shortest time is what many people are looking for. For our most common 3rd-order Rubik's Cube, the fastest record for human handwriting is 4.9 seconds, created by Junior Lucas Etter in November last year; and the machine's record of 3.259 seconds.
Now this record has to be refreshed! A video just released on the video site YouTube showed that a Rubik's cube robot, which was printed by two software engineers Jay Flatland and Paul Rose 3D , took less than two seconds to unlock a third-order cube. According to experimental data, the robot's time to solve the Rubik's Cube is 1.196 seconds, 1.152 seconds, 1.047 seconds, and 1.019 seconds, respectively.
So how does this amazing machine work? First of all, this robot is equipped with four stepping motors to firmly grasp the Rubik's cube. The frame shells are designed by the two individuals and printed in 3D. In addition, there are four cameras installed on the robot. These four cameras are connected to a PC. They continuously scan the color combinations on each side of the cube and send the information to the Kociemba cube algorithm (running in Linux). ), the latter instructs the robot to make the necessary actions. This must be done with all four cameras working together to ensure that the algorithm can get all the information it needs.
Before starting to solve the Rubik's Cube, the operator needs to use a piece of paper to block the camera and manually manipulate the Rubik's Cube. Then put the Rubik's Cube in the specified position, remove the paper, the program will collect the data as fast as possible, and send instructions to the stepper motor, the robot will restore the Rubik's Cube as fast as possible.
Two software engineers are currently applying for the Guinness World Record and have not yet been approved. Of course this is only a matter of time.
