Sonair built its 3D ultrasonic sensor with robotic safety in mind

As robots become increasingly integrated into environments shared with humans, safety considerations are evolving. Sonair, a company based in Oslo, Norway, believes its advanced sensors can assist robotics manufacturers in enhancing safety measures, offering a more effective and cost-efficient alternative to traditional LIDAR technology. The company has developed an acoustic detection and ranging (ADAR) sensor that utilizes high-frequency sound waves to create a three-dimensional representation of a robot's surroundings. By emitting ultrasound waves and analyzing the echoes, these sensors provide crucial data that complements existing cameras and sensors, allowing robots to gain a clearer understanding of their environment. Knut Sandven, co-founder and CEO of Sonair, explained, "Just like humans rely on multiple senses to navigate their surroundings, robots also need various inputs. While cameras are excellent for environmental understanding, they have limitations in reliably detecting objects in all scenarios." Traditionally, robotics companies have depended on LIDAR sensors, which use light beams to gather spatial data. However, Sandven argues that Sonair’s ultrasonic technology provides a more holistic approach, stating, "LIDAR is akin to using a laser pointer. In contrast, our technology fills the room with sound, offering a more comprehensive overview." Sonair's sensors are designed to be compatible with various robotic hardware and software, as they output data in a standard industry format. Since launching earlier this year, the company has witnessed significant interest from the robotics industry, with numerous firms planning to integrate Sonair's sensors into their upcoming models. The industrial safety sector has also shown interest, as these sensors can detect human presence in hazardous areas, enabling automatic shutdowns of machinery to prevent accidents. To accelerate the adoption of its technology, Sonair recently secured $6 million in funding from both new and existing investors, including Scale Capital and Norway’s state-backed Investinor. Sandven noted that investors familiar with the robotics field quickly recognized the importance of addressing safety challenges, especially as robots increasingly interact with people. Fady Saad, a general partner at Cybernetix Ventures, highlighted the ongoing safety concerns surrounding humanoid robots in domestic settings, emphasizing the potential risks they pose to children and pets. As Sonair continues to innovate in the field of robotic safety, Sandven expressed his ambition for the company’s technology to become as ubiquitous in robotics as cameras are today. He is optimistic about the future, stating, "If we reconnect this time next year, we will have a clearer indication of our trajectory."
