Sound Seeing Drone

The Sound Seeing Quadcopter

Avular and Sorama have teamed up to develop a flying sound camera; an innovative system to detect deviations and defects in technical installations.

Industrial installations get bigger and bigger, and smart technology gets better and better. Enough reason for Avular and Sorama to team up and combine both companies’ technologies and expertise to provide a solution for these installations.

Such technical installations require inspections to detect defects for maintenance and repairs. But these inspections are often hard to execute because of the inaccessibility of these huge installations; there aren’t enough borders for workers to walk on, so often scaffolding is required. This means shutting down the installations while being repaired. Obviously, this is a complex and expensive process. And that’s where Avular and Sorama can help.

The project is a MIT Zuid R&D cooperation project supported by Stimulus Programmamanagement.

Complementing expertise

Sorama’s sound camera can accurately measure sound vibrations and use it to generate easier to interpret data by visualizing the sound profiles. Developed algorithms can filter noise to prevent interference and only significant deviations are shown. Every installation has its own sound profile (vibrations), so by detecting changes and deviations it is possible to predict or determine possible unsafe situations.

To use the sound camera in such hard to reach places in technical installations, a mobile version of the camera had to be developed. And what’s more dynamic and flexible in use than a drone?

Avular has years of experience with creating technologies for approaching hard to reach and dangerous places. Avular provides the required knowledge and expertise in the field of localization and integration of sensors, energy supply and data processing in a specialized drone. The drone is a modular quadcopter platform that is completely developed in-house. When the sound camera has detected a defect or leak, it’s up to the drone to accurately localize. Using Real Time Kinematic GPS technology, the drone can localize defects up to 2 centimetres accurate.

The partnership is a logical one; both companies complement each other on the expertise needed for this project. After successful development, both Avular and Sorama will bring the system to market, both in their own domain.

Dutch Design Week 2019

The Sound Seeing Quadcopter will be displayed during Dutch Design Week 2019 at Strijp-T, where both Avular and Sorama are located.
