ADAR One Sets 3D Safety Benchmark

The world’s first safety certified 3D ultrasonic sensor just hit the market.

Sonair’s ADAR One is designed for autonomous mobile robots and industrial automation, delivering 180°×180° 3D spatial awareness that sees people and obstacles at all heights. By embedding a compact acoustic detection and ranging sensor flush into a robot’s form factor, ADAR One promises to extend safety coverage beyond what traditional 2D scanners can offer. The company frames it as a safety layer that sits beneath the AI stack and motion system, independently verifying the space around a robot before it moves.

The push behind ADAR One is not just smarter sensing, but safer sensing verified by rigorous standards. The device was assessed as a human protection sensor under IEC 61496, the electrosensitive protection standard, and meets two foundational safety benchmarks: IEC 61508, the functional safety standard for electronic safety systems in high-risk environments, and ISO 13849, the universal standard for safety-related parts of control systems. The certification package is substantial: ADAR One is rated SIL 2 (Safety Integrity Level 2) and PL d (Performance Level d) with a PFH below 1.5 × 10^-7 per hour, and exida in Germany served as the assessing body. The project required a deep, laborious certification process that Sonair says involved relentless testing and documentation, a reflection of the industry’s growing insistence on robust safety before deployment.

The new sensor arrives as safety infrastructure lags behind advances in AI and perception. Traditional 2D laser scanners can define safety perimeters but struggle to detect humans and objects beyond a single plane. ADAR One’s 3D approach aims to close those blind spots, enabling robots to reason about space in all directions and at varying heights. The 3D perception is positioned as a foundational safety layer that can work with any camera, AI stack, or motion system, providing a verifiable space that can prevent unsafe interactions before they occur.

In practical terms, the sensor’s small footprint and flush integration are not just cosmetic choices; they are critical to deployment in crowded or space-constrained robots, including humanoids. The design allows ADAR One to be embedded directly into existing robot platforms, reducing the need for bulky add-ons and simplifying retrofits. Since the beta version was introduced, more than 80 global robotics companies have rigorously evaluated the sensor through Sonair’s test program, a signal of broad industry interest and the potential for rapid adoption in diverse workflows. The case study reports that this level of validation and certification is intended to give system integrators a clearer, safer path to compliance while shrinking the risk that new autonomy features will be delayed by safety bottlenecks.

From a plant-operations perspective, the promise of ADAR One rests on more than safety ratings. The ability to verify space comprehensively, quickly, and independently of other systems could shorten the time to detect and respond to human presence, potentially improving cycle times in collaborative settings and increasing throughput where humans and robots share work zones. Yet the real value will hinge on how quickly teams can integrate the sensor with their existing safety architectures and how well it interoperates with current planning and control software. The case study assigns a central role to the sensor as a safety foundation rather than a single device in a larger stack, underscoring the need for alignment across peripherals, AI, and motion control.

Practitioner insights:

Deployment data shows broad interest and validation, with industry players evaluating ADAR One across a range of autonomous and manual-assistance scenarios. The case study reports that the sensor’s combination of 3D perception, compact integration, and formal safety certifications positions it as a meaningful new baseline for human-robot collaboration in factories and logistics centers.
