2G Robotics has recently launched the ULS-200, a mid-range underwater laser scanner. The most versatile of 2G Robotics’ series of ULS systems, the ULS-200 provides many of the benefits of the small, short-range ULS-100, while allowing for the extensive variety of applications provided by the larger, long-range ULS-500.




Advantages of the ULS-200:

Increased scanning range – The ULS-200 ideal scan range is between 0.25m and 2.5m. This longer scanning range makes the ULS-200 relevant to a more extensive range of applications.


Compact design – The ULS-200 retains the compact, lightweight design of the ULS-100 (1.29kg in water). At just 29.2cm in height and 33.2cm long, the ULS-200 is capable of underwater measurements in confined spaces, and as with all ULS scanners, can be easily deployed by a diver.


Low power consumption and bandwidth needs – Requiring minimal power (12 VDC to 24 VDC @ 1A maximum) for operation, the ULS-200 also utilizes standard RS-485 and RS-232 connections, making the system easily compatible with almost any ROV/AUV.


Applications for ULS-200:

These features make the ULS-200 extremely versatile. The system is relevant to a wide range of measurement tasks (in water or air) that require precision and accuracy. Some examples of these underwater inspection applications include:


Offshore          Inland & Rivers           Nuclear           Research & Environmental

Offshore Jacket Inspection     Dam and Bridge Inspection    Small Crack/Chip Measurement  Underwater Archeology

Offshore Damage Assessment          Water Treatment Plant Inspection     Patch Fabrication      Marine Biology

AUV Navigation

Offshore Metrology     Tunnel Inspection


Pipeline Inspection     Well Inspection


Chain Measurement



Ship Hull Inspection



Ship Propeller Inspection





How the technology works:

As with 2G Robotics’ other models, the ULS-200 employs innovative laser technology and features silt and ambient light filtering functions to produce very highly detailed 3D scans at resolutions hundreds of times higher than that of sonar technology. Operable to depths of 350m, the ULS-200 emits a line of laser light, which reflects off the target and is captured by the device’s optical sensor. The sensor then triangulates hundreds of points along the laser line, collecting up to one million points per scan, creating a detailed digital 3D model. Because the system’s laser technology gathers such dense data measurements, the ULS-200 is able to produce extremely precise scans that accurately resolve fine details such as cracks, dents, or other anomalous features pertinent to a structure’s integrity. The ULS-200 therefore redresses significant limitations posed by sonar technology, which proves ineffective in small, echo-prone spaces and creates low resolution models that can lead analysts to make risky, assumption-based decisions.
