01 / Overview

The exhibit is presented through a combination of electromechanical and multimedia interactive methods. By setting up cartoon shaped robots, the third-order Rubik's Cube that has been arbitrarily disrupted by visitors is restored, creating a bridge for communication between visitors and the robots. The exhibit the integrated application of pneumatic robotic arms, image recognition technology, logical operations, and artificial intelligence.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

The Rubik's Cube robot uses an industrial grade CCD camera to take photos of the six faces of the chaotic Rubik's Cube, and transmits the data to a computer. The computer calls a program to recognize the color of the Rubik's Cube, and then inputs the color processing results into the Rubik's Cube restoration algorithm. The algorithm calculates the steps of Rubik's Cube restoration in a short time and converts the restoration sequence of the six rotational degrees of freedom into a restoration sequence of two rotational degrees of freedom suitable for the robot through a state transition function. The restoration sequence is output through the computer I/O port, driving the solenoid valve to act, and ultimately driving the robotic arm to complete the Rubik's Cube restoration action.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
