An UAV equipped with NTR’s navigation system can operate in a closed, dark environment, such as an oil tank. Unique algorithms use sensor information and SLAM processing technology to navigate the UAV in GPS-denied environments and control its movement. It performs a comprehensive survey, build a three-dimensional model and assess the tank’s condition. The UAV uses AI/autonomous navigation algorithms to make its way independently to the target. A UAV on our platform can perform technical inspections of dangerous, totally enclosed spaces, such as tankers and oil tanks; as well as do warehouse inventory, surveillance systems, delivery of goods, etc. Our platform can be tweaked to develop navigation systems for similar robots, such as crawlers.
