Rava

Rava is an interactive lamp that explores the phenomena of light, specifically of lasers. It combines the approaches of physical computing, mechatronics, design ,and technology to create a simple delightful interactive experience. The laser refracts and bends at various intensities depending on one’s proximity to the lamp.

Process & Prototype

The design of Rava went through various stages of sketching, prototyping, and material studies. Inspired by a PLEXIGLAS® workshop, Rava utilizes a bulk modified PMMA tube as a core element. The acrylic rod refracts the laser and small particles inside the rod make the laser visible even during daylight. The frosted acrylic subtly blends and contrast with the transparent acrylic rod. Various “works like” prototypes and coding variations were tested to optimize the interaction.

Mechatronics

The neutral position of Rava set at 90 degrees. An ultrasonic sensor detects proximity. The Arduino translates the distance into a set degree of turns in a servo motor, resulting in a pendulum effect. The laser, connected to the servo is pointed towards the acrylic rod. At a closer distance, the servo turns a greater degree resulting in more bends. These components are tightly and strategically placed in a custom wooden body to minimize the size of the unit and maximize the effect of the phenomena. For easy access to the electronics, a magnetic cap is imbedded to keep its pure form.
