I’m So Old, I Actually Used To Call People On My Phone And Talk To Them

“The mechanics are constructed entirely from LEGO, including four MINDSTORMS NXT kits, with the addition of a Samsung Galaxy S II smartphone running a custom Android app as the robot’s brain. Both the MINDSTORMS NXT kits and the Samsung Galaxy SII use a variety of ARM –based processors.

The app uses the phone’s camera to capture images of each face of the Rubik’s Cube which it processes to determine the scrambled colours. The solution is found using an advanced two-phase algorithm, originally developed for Speedcuber, enhanced to be multi-threaded to make effective use of the smartphone’s dual-core ARM Cortex-A9 1.2GHz processor. The software finds an efficient solution to the puzzle which is optimised specifically for the capabilities of the four-grip mechanism. The app communicates via Bluetooth with software running on the ARM microprocessors in the LEGO NXT Intelligent Bricks which controls the motors driving the robot. During the physical solve, the app uses OpenGL ES on the phone’s ARM Mali-400 MP GPU to display a graphical version of the cube being solved in real time.”

From Tinkernology:

This system uses four Lego parallel robots which are fed by two conveyor belts. As items flow down the conveyor belt toward the robots, each item passes by a light/color sensor mounted on each conveyor. When the item is detected, a signal is sent to the robots telling them information such as the color of the object, which belt the object is on and the position of the object on the belt. The robot reaches out and grabs the item from the moving conveyor belt when each item gets close enough and moves it to a location based on the color of the item.

The cell is capable of picking and placing objects at a rate of 48 items per minute. Each robot can move 12 items per minute, or it can move an item in 5 seconds!

You know what they say: Hands that pick up LEGOs never pick up chicks. He’s smart to make a machine to do it for him, leaving him more time to be the Dos Equis guy.
