The term “autonomous underwater vehicle” also refers to an uncrewed underwater vehicle. These can be used for submerged survey tasks like recognizing and charting underwater wrecks, impediments, and rocks and that could pose a danger to commercial and fun vessels’ navigation.
It finishes its survey mission without an operator. When a mission is completed, the AUV will return to a position that was pre-programmed to download and process all the data.
Working of the UUVs
UUVs are surveillance robots pre-programmed with mission stipulations before deployment. These can drift, sail, or quicken themselves through water contingent on their design. Non-propelled AUVs moreover hover in the water column or glide by changing their resilience. When compared to propelled AUVs, these consume little power, are suggestively less nimble, and are frequently deployed on longer missions.
Positioning of UUV’s
UUVs, different from other robotic systems, can’t use global navigation satellite systems. They make use of GPS navigation and can only get a GPS signal when it is on the surface. When it is underwater, it makes use of its last recognized GPS position to calculate its movement, measured by an onboard inertial navigation system monitoring the UUV’s velocity, acceleration, and rotation. This is called “dead reckoning.” Doppler velocity logs might also be utilized to regulate the speed of the robot related to the ocean floor, but just when the machinery is merely not itinerant too much higher from the bottommost.
What are the Applications of UUVs
• UUVs are utilized by oil drilling and subsea drilling industries to inspect the right marine area for their requirements.
• UUVs are employed as maritime technology to see whether any booby-traps are hidden in the ocean bottom.
• When it comes to the deployment of UUVs for study, this comprises searching for any sort of damage to the underwater ecology on the sea floor.
