Nowadays, new technology is rapidly shaping the way how construction projects are delivered. The application of unmanned aerial vehicles (UAVs) is one of these examples. Unlike conventional aerial measurement by aircraft, it doesn’t require expensive aeronautical facility and trivial procedure. Comparing to other surveying approaches like using the GPS navigation, the UAV systems can outperform in many large-scale projects by saving cost and time. There many explorations to potential applications of UAVs - budget and schedule control, construction innovation, and safety practices. However, in the United States, the Federal Aviation Administration (FAA) regulations and many state regulations often prevent or limit the wide use of UAVs. In …show more content…
To fulfill that goal, the booming technology like point cloud technology can be utilized with the UAVs. In construction aspect, the point cloud data is a set of coordinates produced by 3D scanning process which executed by the UAVs. By software like Geomagic Studio, the point cloud data for the job site can be converted into 3D topographic, or the sections inside the building can be transformed into 3D models. By the year 2018, the domestic UAV industry is expected to grow to be a $13.6 billion market (Hanna, 2014). Due to the small payload of the UAVs and the movement attributions in the flight, the most of unmanned aerial vehicles utilized in the construction site cannot be equipped with professional cameras. However, the data collected by UAVs still meets the accuracy requirements for the construction. Comparing to other surveying options like using measure station or GPS equipment, the data collected by UAV systems can still outperform the data measured by traditional equipment and techniques in cost and time. Therefore, with proper construction strategy, the UAV systems with point cloud can be a promising tool for construction. It is important for construction managers to consider value engineering which means balancing three elements: quality, cost, and schedule in the construction process. Basically, applying UAV system with point cloud technology can improve the overall construction efficiency through three aspects: improving the
Although the potential contribution of UAVs to sectors such as environmental protection, law enforcement and various commercial activities is apparent, they still seem not to be ready for civilian use. This is due to several reasons, including e.g. civilian UAVs (CUAVs) requiring different technological solutions such as optimized platforms, different endurance requirements, dedicated payloads and different ground control systems. An additional important problem to be solved is the integration of UAVs in the civilian airspace, which will require the adoption of civilian airworthiness standards and proven safety features. Last but not least trust has to be created, both at the public sectors and the commercial community, that CUAVs have economic advantages ( Vanclay 2003)
In the recent past, a lot of research has been going on to establish the role unmanned aerial vehicles can play in the economy. Just the other day, the Association for Unmanned Vehicle Systems International (AUVSI) released a report which explained in totality, how best this equipment could be used to propel economic growth.
It’s important to see these kind of operations taking place, not only for laws and regulations to take shape, but also for the drone industry to expand and show what drones are capable

To begin I will give some history of Drones (UAVs). The history of drones is actually a fairly long time line in our history beginning in about 1863 with the patent of an unmanned aerial bomber by a man from New York City named Charles Perley. This invention known as Perley 's Aerial Bomber was a design consisting a hot-air balloon that would carry a basket filled with explosives attached using a timing mechanism that would trip the balloon 's hinged basket and effectively dropping the explosives and igniting their fuse in the process. A very ingenious design in the era it was created in. There were drawbacks to this design though is that it was inaccurate and
The growth of UAVs has been almost as remarkable as the growth of aviation. During just the Iraq war, the amount of UAVs used in operation has been grown from a handful in 2003 to approximately in 5300 in the Department of Defense alone (Singer 35). This number does not include the use of drones by other governmental agencies such as the Central Intelligence Agency and the Department of Homeland Defense. Furthermore, much of the technology afforded to manned aircraft has been extended to UAVs such as stealth capabilities and the adaptation of air-to-ground weapons. Note that
This article from NASA explores the possibilities that drones have to offer in many different scenarios. However, it recognizes the need of some type of infrastructure or mapping for these UASs to operate successfully and efficiently. NASA suggest leveraging concepts used on roads to be implemented into a cloud based infrastructure that UASs could recognize and follow. Further the article explains technologies that NASA is exploring to create a UAS Management System, including testing that has already been conducted. Dr.Kopardekar offers good concepts on what drones could possibly accomplish one day. He reveals the underlying problem that there is an absence of a management system to allow drone to efficiently carry out autonomous tasks on
You have probably seen a small plane flying in the sky which is similar to the children's toy airplane. It was called Drone. It is a very popular technology today, especially for photographers. It is also very useful in daily life, but at the same time, there are many disadvantages. The drone is also known as UAV (Unmanned Aerial Vehicle), it is aircraft which does not need a human command to fly on it. But it is controlled by a remote computer system. There are two types of this system, remote control and fly manually by entered with a complex program. Most of the drones are designed in the form of four blades which is designed for fast blowing and slow blowing to fly higher and lower, as well as tilting and flying in different directions. Actually, Drone was
An increased traffic flow of both manned and unmanned aircraft will most definitely increase the probability of collision in the air as well as on the ground. This can lead to human casualties and injuries. In order to fortify safety of use new technologies must be designed, tested, and integrated into the current and future UAV
Commercial Drones Market by Type (Fixed Wing, Rotary Blade, Quad Rotor), Technology (Energy & Propulsion System, Automation, Collision Avoidance), Application (Government, Agriculture, Manufacturing, Retail) & Geography - Global Forecast to 2020
In recent years, unmanned aerial vehicles (UAV), or drones, have transitioned from primarily military applications to use in the private sector; being used to film movies, delivering packages for Amazon, and even personal entertainment. Because of the advancement in drone
The first fissure in the Indian approach to UAVs is that all possible concerns have not been identified with care and rationality. The DGCA guidelines have evidently taken a very airspace-centric view, with little acceptance of the reality that there is still a wide road for present consumer UAV technology to cross to compete with manned aircraft for high-altitude airspace. The guidelines also overtly put a ceiling on UAVs from operating in controlled airspaces but in all other respects regulate them with the primary intent of avoiding collisions. In doing so, the guidelines lose sight of the fact that in low-altitude spaces; the odds of divergence are actually a little on the higher side between landowners and UAV operators.
Embry Riddle University has also designed its own VTOL UAS that has achieved notoriety and funding from the Space Florida-Israel Innovation Partnership Program (Pinholster, 2017). The tail-sitter VTOL designed by university researchers’ named the Mark III is designed to be used in precision agriculture applications, security and surveillance missions, building and bridge inspections, and search and rescue missions (Pinholster, 2017). With its advanced flight control algorithms the platform can survey 250 acres of farm land in 20 minutes (Pinholster, 2017). The Mark III is representative of current and future uses of VTOL UAS see Figure 3 below.
Drone technology is advancing rapidly and it is changing the way in which things are being done. Drones are widely used by many people as a hobby or for career purposes, as well as for military purposes by the United States. Drones provide the U.S military with many benefits, which helps the military to operate efficiently and in a safe manner. Businesses are utilizing this technology as well in order to make their companies run more efficiently, as well as to improve their customer service. Drone technology will positively impact our society; drastically change our culture and political system and definitely advance our economy as well as help enhance our environment.
The popularity of drones being used in the military has increased over the last decade. The prospect of using drone has ignited widespread debate over its usage. However, this debate is currently focused on America and some of its allies in using for surveillance and some strike missions with enemies in Afghanistan and Pakistan and against alleged terrorist around the world under the banner of unnamed war against terrorism. Although this is the case, there is much other potential utilization of the drone technology. Most of the growth in the industry will be from the commercial or the civilian side, an example of which is Amazon’s drone delivery service. Another example is the use of drone off a handful
