Origami Dancing Cranes | Dancing Paper


Japanese designer Ugoita T. has decided to give life, in a surprising way, to golden inanimate origamis : he has designed little paper creatures and placed them on an electromagnetic stage that provokes synchronized movements. “Dancing Paper” is to discover through a funny video. Ugoita T. posted this video, using an electromagnetic box, some paper cranes, and a set of magnets to create one of the most adorably charming dance routines we’ve ever seen performed by inanimate objects.

dancingUsing magnets to move objects from below isn’t a new concept. Many of us have seen the “ice skating pond” Christmas decoration which uses the same effect. Unlike the skating pond,Dancing Paper has moving parts (other than the cranes themselves). Under the plastic surface are a series of individually controlled electromagnets. Each of the supporting dancers has a line of four magnets, while the featured dancer in the center has a 5×5 matrix. The 41 electromagnets were wound around bolts with the help of a Tamiya motor and gearbox.

The actual dance moves are controlled by C code which appears to be running on an Atmel microcontroller. Of course a microcontroller wouldn’t be able to drive those big coils, so some beefy TO-220 case transistors were employed to switch the loads. The cranes themselves needed a bit of modification as well. Thin pieces of wire travel from the neodymium magnets on their feet up to the body of the crane. The wire provides just enough support to keep the paper from collapsing, while still being flexible enough to boogie down.

UGOITA is a group of amateur “salaryman” gadget lovers who formed together in 2012. Rationale for their activity is to create something that “moves.” However, looking back, most of the works they made were actually things that didn’t move. Some the things that actually moved are: Game-cassette-shaped Electronic Harmonica, “8bit Harmonica” A lamp that absorbs color, “Clip Lamp” An umbrella that plays music, “Musical Rain”. Ugoita has a variety of projects that explore how technology might intersect with more traditional objects. Below, his 8bit Harmonica project, a NES sound effects instrument, and a Musical Umbrella that translates the raindrops into adorable electronic tones.
