Robots

NV5 Geospatial’s Automated Roving Inspection System (ARIS) is the most advanced toolkit for remote substation and infrastructure inspection, combining fine-scale spatial mapping with high-sensitivity corrosion
and thermal detection. With a sensor stack including a lidar sensor, thermal camera, and spectral camera, the ARIS goes beyond visual inspection to assess the health of components on a quantitative basis. The sensor bundle is mounted on an autonomous roving vehicle capable of performing repeat observations in nearly any substation environment, navigating rough terrain in any weather conditions with repeat positioning to within 10 cm. The ARIS can safely navigate most potential hazards for routine or post-storm asset health assessments.

Why Autonomous Rovers?

Autonomous vehicles are ideal platforms for surveying areas dangerous for people such as electric substations, mines, and hazardous materials sites.  They excel in repeat surveys for monitoring an area to assess environmental changes over time.  

Autonomous Applications

Data generated from the suite of sensors in the ARIS is used to detect small-scale damage and signs of degradation (cracks, leaks, and oxidation) and to map physical change to fence line, transformers, switches, conductors and other components. The deployment of this technology will allow a utility to roll out the most advanced substation monitoring program achievable today.

Changing Responses to Changing Disasters

"The data collected is at a resolution and accuracy that is far superior to what we have had available to us. Some of these areas have not been surveyed since the Civil War era, and the technology being used provides us insights on water depth for our nautical charts, especially in shallow areas that are impossible to chart by more traditional means. These surveys will provide an important baseline and offer long-lasting value to other stakeholders, who will leverage it for a variety of applications."
