Sonair’s Dolphin-Inspired Ultrasound Tech Could Revolutionize Autonomous 3D Vision
A Breakthrough in Affordable, Energy-Efficient Spatial Awareness
Norwegian startup Sonair is pioneering a novel approach to 3D computer vision by harnessing ultrasound technology - taking inspiration from how dolphins navigate underwater. The company recently secured $6.8 million in funding from investors including Skyfall and RunwayFBU to bring its innovative solution to market.
Why Ultrasound Could Disrupt Lidar Dominance
Traditional autonomous systems rely heavily on lidar technology, which comes with significant drawbacks:
- High costs that limit widespread adoption
- Limited operational range in certain conditions
- Susceptibility to interference from light and reflective surfaces
Sonair’s ultrasound-based system offers compelling advantages:
- 50-80% cost reduction compared to lidar solutions
- Minimal energy and computational requirements
- Effective object detection through sound wave interpretation
“Our mission is to replace lidar,” states Knut Sandven, Sonair’s founder and CEO. “We’re starting with autonomous mobile robots, but our vision extends far beyond.”
How Sonair’s Technology Works
The system combines several innovative components:
- Beamforming Technology: Borrowed from radar systems to direct and focus sound waves
- AI-Powered Processing: Advanced algorithms interpret ultrasound data for precise object recognition
- Hybrid Approach: Works alongside cameras to enhance spatial accuracy
Current capabilities include:
- 180-degree field of view
- 5-meter operational range
- Reduced sensor requirements compared to lidar
From Research Lab to Commercial Reality
Sandven, a serial entrepreneur whose previous MEMS-based gas sensor company was acquired, discovered the core technology at SINTEF - Norway’s premier research organization. Recognizing its potential, he:
- Acquired the intellectual property for acoustic ranging
- Brought on the original research team
- Founded Sonair to commercialize the innovation
Market Potential and Future Applications
With projections of 200,000 autonomous mobile robots entering the market in 2024 (worth $1.4 billion), Sonair is strategically positioned to capitalize on the growing demand for affordable perception systems.
Potential future applications include:
- Automotive: Supplementing or replacing current sensor arrays
- Wearables: Enabling touchless interaction through proximity detection
- Healthcare: Enhancing assistive devices for the visually impaired
“With reduced costs in sensor technology and AI advancements,” notes Skyfall partner Preben Songe-Møller, “industries from manufacturing to healthcare are poised to benefit.”
The Road Ahead
While initially focused on indoor robotic applications, Sonair plans to expand into:
- Outdoor autonomous systems
- Automotive safety features
- Novel human-machine interfaces
The company’s dolphin-inspired approach demonstrates how biomimicry can lead to technological breakthroughs that are both innovative and cost-effective - potentially reshaping the future of autonomous perception systems.
