Unmanned aerial system technology is very versatile. One big money saving capability is for use of UAS technology in structural and zone inspection and analysis. For example in the University of Vermont area, there is only one boom lift. This can be problematic as there is a large area with only one lift. Inspection of structures is a time-consuming, expensive, and difficult task especially with only one lift. Examination of structures for damage caused by the ageing, natural disasters etc… is definitely worthwhile to preserve the value of the structure to ensure safety and functionality. Structures, for example bridges or towers, are often damaged in places where the naked eye could not detect. There used to be only one way of inspection, using conventional methods. Such as, boom lifts or scaffolding. Both options are very costly to operate or erect. Additionally, these operations can be obstructions to traffic and pedestrians. UAS is the most cost effective and cost saving professional grade solution for inspection and maintenance of structures. The operational cost in the long run of UAS compared to more traditional methods like using boom lifts or scaffolding is very minimal. Modern drones are now capable of mounting various types of sensors that can capture high quality images in multiple spectrums.

For example, one could mount something like the Sony rx100 VI which takes 20.1 megapixel images, or a more specialized sensor like the Parrot Sequoia which takes multispectral images. The Sony takes more traditional images which can be used to create an orthomosaic. The data can also be used to create 3D models which would be especially helpful in the context of structural inspection and analysis. These sensors can be installed on drones which allow technicians to inspect, roofs, facades, bridges, and other structures. Which allow them to be examined with ease while also taking less time for them to find damage caused by ageing, erosion damage, or corrosion. Breaks in the stone work, stores, attachments, spalling of concrete, harmed joints, split concrete, broke tiles or harm to seals are unmistakably noticeable from the air. Harm can be examined and archived with the high-determination aeronautical photos made by the automatons. Specialized structures, for example, spans, smokestacks, towers, rooftops or damming structures can be analyzed for conceivable harm amid the observation flights with rambles – amid activity and with no hazard to people who end up in the region of the inspection. The standard assessment of structures for harm caused by the maturing procedure is certainly advantageous to safeguard the estimation of land, verifiable structures, extensions, structures, and landmarks in the long haul. Exteriors, rooftops and specialized superstructures can experience a nitty gritty check for harm with the assistance of automatons and high-determination cameras. Poor workmanship or guarantee cases would thus be able to be recognized at a beginning period. Automatons are in this way, in a perfect world suited to completing support work, building investigations/examinations of structures. Harm to sunlight based boards, protection, or lines can regularly not be seen with the striped eye. Thermography utilizing rambles recognizes warm scaffolds, spills and auxiliary deformities in a solid way.

For instance, a building’s protection can be investigated with warm imaging cameras joined to the automatons. Indeed, even warm misfortunes on rooftops and different parts of structures can be envisioned with thermography. After the ethereal study with an automaton, specialists can assess the thermographic pictures. Harm documentation can be made with the assistance of thermographic reports. Future support assignments and any essential repairs can be gotten from these. Drones rely on a number of sophisticated technologies, but many of these are still under development. Until we see improvement in the following areas, many of the most innovative UAS applications will remain at the concept or pilot stage, including those related to drone delivery and transport. Autonomous flight. While a few drones can already fly without a user directing their path, this technology is still emerging. Over the next five years, system-failure responses, dynamic routing, and handoffs between human and machine controllers should improve. With greater autonomous control, companies can pursue uses that are now elusive, such as the repeated and unpiloted surveillance of pipelines, mines, and construction projects. Battery performance. Rapid improvements in battery technology will also unlock new value from drones.

The energy density of lithium-ion batteries is improving by 5 to 8 percent every year, and their lifespan is expected to double by 2025.6 These improvements will allow commercial drones to fly for more than an hour without recharging, enabling many new uses. Detect-and-avoid technologies. These systems, which help drones avoid collisions and obstacles, are still in development, with strong solutions expected to emerge by 2025. (Drones that hobbyists use have some detect-and-avoid systems, but they are relatively unsophisticated.) Integrated air-traffic-management (ATM) systems. Drones currently fly below the height of commercial aircraft because of the collision potential. UTM solutions that can track drones and communicate with air-traffic-control systems for typical aircraft are not expected to materialize for more than a decade, making high-altitude flights impossible until that time. Location technologies. Drones must be able to identify their location even in areas where GPS signals are limited or degraded, such as densely built cities and remote locations. Like air-traffic-management integration, the widespread rollout of a GPS alternative is more than ten years in the future.

Unmanned Aerial Systems have been perceived poorly in the media. As the technology becomes cheaper, more consumers can get their hand on it. Consequently, they are put under fire due to the average consumer having no knowledge of FAA regulations. Now whether as drones get smaller and cheaper, are safety regulations keeping up? Appealing to the growing market of amateur drone enthusiasts, Chinese drone maker DJI unveiled its newest model, the Mavic Pro, which can fit in the palm of your hand when collapsed. It also has a desirable a 12 megapixel camera capable of shooting in 4k. It is also capable of flying up to 40 miles per hour. The Mavic Pro’s specs are similar to DJI’s higher end Phantom 4, which is intended for more experienced drone operators. The Federal Aviation Association (FAA) released its unmanned aircraft systems guidelines in June of 2016. However, some are worried that even with the new guidelines, hobby drone use has outpaced safety. Fall of 2016, congress proposed a bill called the Consumer Drone Safety Act, which would have required manufacturers to sell safety information with drones and place technological safeguards into the drones themselves. Senator Charles Schumer of New York, along with Senator Dianne Feinstein of California, expressed frustration with unchecked drone use. However, looking beyond the media’s perception UAS technology, there are many capabilities. These capabilities can bring new opportunities for businesses.
