Russian folk bot is an electro-acoustic orchestra

Moscow-based artist Dmitry Morozov has created a number of Arduino-powered projects covered by Bits & Pieces over the past year, including a musical tattoo reader and the ‘Signes de vie’ (‘Signs of Life’) installation.

His latest project? The gusli robot, which Morozov describes as a Russian folk bot and portable electro-acoustic orchestra.

Recently featured on the official Arduino blog, the folk bot, which is inspired by the oldest Russian multi-string plucked instrument, is powered by two Atmel-based Arduino Uno boards (ATmega328 MCU).

Additional key specs include:

  • Servo motors x6
  • DC motor x1
  • Stepper motor x1
  • Solenoids x3
  • Spings x8
Strings x38

“‘Gusli-samogudy’ means self playing gusli,” Morozov explained. “It’s very common charter is old Russian fairy tales – so by making it robotized I made [the] fairy tale come true.”

Signs of Life with a fax machine and Arduino Uno

Dmitry Morozov describes his ‘Signes de vie’ (‘Signs of Life’) project as a light model of a simple cell colony built on the principles of one-dimensional cellular automaton. Interestingly, the unique light and sound mechanism is based on an old fax machine.

“A fluorescent dye is applied on special fax paper, [while the] thermal printing element is replaced by a row of 10 LEDs,” the Moscow-based artist explained. “As it goes through a step-by-step under the row of diodes, it leaves on a paper a glowing trace from short flashes: a row that corresponds to one generation of cellular automaton. Gradually, each of the rows fade and is being replaced by a new one, but the glowing time is enough to see the whole pattern of the colony.”

Thus, says Morozov, the paper becomes a kind of a chronicle of the colony’s life.

“One of the 256 algorithms (rules – more info) of the simplest one-dimensional cellular automation can be used. Those are selected by a switch,” he continued. “Additionally, there is a speed switch that selects appearance time-frame of each new generation in the range of 1 to 18 seconds.”

In addition to the above-mentioned fax machine, the project also features an Arduino Uno (Atmel ATmega328) and a small speaker through which an algorithmic composition is played – with pitch and spacing of repetitions directly dependent on the conditions of the selected rule.
