Knut Sandven founded Sonair, a Norwegian business that is leading the way in an innovative use of ultrasonic technology for 3D computer vision in autonomous hardware. Sonair’s ultrasound-based sensors provide a low-cost substitute for more popular LIDAR systems, allowing for the 3D detection of persons and objects while consuming less energy and processing resources. The business has raised $6 million to further develop its technology, with an initial focus on autonomous mobile robots (AMRs), from early-stage investors Skyfall and RunwayFBU.
Dolphin sonar, also known as echolocation, is a sophisticated biological system that dolphins use to navigate, hunt, and communicate in their underwater environment. Similar to dolphin sonar but used in the air, Sonair’s technology uses ultrasound to interpret sound waves and generate 3D models. The concept was created by seasoned businessman Sandven after he purchased MEMS-based ultrasonic sensor intellectual property from renowned Norwegian research organization SINTEF. His objective is to replace LIDAR systems, which, although widely used, are costly and susceptible to interference from the environment and range issues. With Sonair’s technology, sensor package costs can be lowered by 50% to 80%.
In order to provide precise geographical information for autonomous systems, the ultrasonic sensors collaborate with cameras using a beamforming approach similar to that of radar. AI algorithms analyze this data to identify objects, producing a five-meter-range, 180-degree field of view that is detailed. While solving some of the limitations of LIDAR, the company’s technology also requires fewer sensors.
Though Sonair’s technology is currently centered on robots, it has wider applications. To improve the accuracy of touch-based feedback, Sandven thinks that it may be modified for wearable technology. To improve reaction accuracy, Sonair’s sensors could provide data as a hand approaches an object rather than detecting pressure after contact.
Sonair envisions an immediate opportunity for growth, with forecasts indicating that 200,000 autonomous mobile robots will be developed by 2024. Healthcare and manufacturing sectors alike expect to benefit from Sonair’s creative and economical solution as AI and sensor technology develop.
