The quadcopter represents one of the emerging research areas in unmanned aerial vehicle (UAV) technology. One of its advantages lies in its simple mechanism and smaller propeller size compared to helicopters, while maintaining the same lifting capacity. The quadcopter employs inner and outer control schemes, where the inner control manages attitude roll, pitch, yaw, and altitude, thereby affecting the motion of the quadcopter. Meanwhile, the outer control governs the direction of the quadcopter's movement. This condition underscores the significance of inner control, ensuring the quadcopter's maneuverability. Consequently, there is a need to design an attitude, pitch, and roll control using the PID method. This experiment focuses on roll and pitch control under hover conditions. The PID control experiment yielded optimal results with parameters KP = 60, KI = 22, and KD = 14, exhibiting rapid response, absence of oscillation, deviations smaller than 20o in both roll and pitch controls, and the ability to return the attitude to the initial setpoint position when disturbances occur. Keywords: Attitude, hovering, PID controller, quadcopter. ABSTRAKQuadcopter merupakan salah satu bidang riset yang baru dalam teknologi unmanned aerial vehicle (UAV). Salah satu keunggulan pada Quadcopter adalah mekanisme yang sederhana dan ukuran pada baling-baling yang lebih kecil dibandingkan dengan helicopter dengan daya angkat yang sama. Quadcopter memiliki skema kendali inner dan kendali outer, dimana kendali inner mengendalikan attitude roll, pitch, yaw, dan altitude yang berimplikasi pada gerak quadcopter. Sedangkan kendali outer mengendalikan arah gerak quadcopter. Kondisi ini menjadikan kendali inner sangat penting sehingga mampu menjaga quadcopter dapat bergerak. Untuk itu perlu dirancang suatu kendali attitude pitch dan roll dengan metode PID. Eksperimen ini focus pada kendali roll dan pitch di kondisi hover. Hasil eksperimen kendali PID pada roll dan pitch didapatkan hasil terbaik pada parameter KP=60, KI=22, dan KD=14 yang memiliki respon cepat, tidak terjadi osilasi, lonjakan lebih kecil dari 20o baik pada kendali roll maupun pitch, dan mampu mengembalikan attitude pada posisi setpoint awal apabila diberi gangguan.<div id="gtx-trans" style="position: absolute; left: -26px; top: 21px;"> </div>

“…Most wildlife-related wetland UAV studies in our pool have focused on birds (seven out of ten papers) with two others considered mammals [100,102] and crustaceans (crab) in relation to illegal trapping [97]. One study assessed a broader suite of coastal habitats with salt marshes and mudflats among those [104].…”

“…Inventories of bird colonies are especially well facilitated by UAVs when targeting larger waterbird species or their nests located on top of plant canopies [36,101,103], both through human [101] and automated machine-learning image recognition [36,63]. Wildlife detection potential can be substantially amplified by the use of thermal cameras that enhance identification of animals based on the contrast between their body temperatures and environment [102]. In avian studies, unique thermal properties of nesting material can also help identify nest features from thermal data even when the birds are not present [101].…”

“…It is also critical to anticipate and minimize the effects of potential field survey shortcomings on data post-processing and information extraction. For example, sharpness and exposure in visible and thermal camera settings may strongly affect the quality of images and ease of visual interpretation of wetland targets [34,101,102], which means that failure to select the appropriate settings can render the ultimate datasets much less usable. Relatedly, allocation of ground surveying units (e.g., vegetation plots) should anticipate potential challenges in their co-location or identification from UAV data and, when possible, record assisting information, such as cost-effective ground photographs [139,146].…”

Recent developments in technology and data processing for Unoccupied Aerial Vehicles (UAVs) have revolutionized the scope of ecosystem monitoring, providing novel pathways to fill the critical gap between limited-scope field surveys and limited-customization satellite and piloted aerial platforms. These advances are especially ground-breaking for supporting management, restoration, and conservation of landscapes with limited field access and vulnerable ecological systems, particularly wetlands. This study presents a scoping review of the current status and emerging opportunities in wetland UAV applications, with particular emphasis on ecosystem management goals and remaining research, technology, and data needs to even better support these goals in the future. Using 122 case studies from 29 countries, we discuss which wetland monitoring and management objectives are most served by this rapidly developing technology, and what workflows were employed to analyze these data. This review showcases many ways in which UAVs may help reduce or replace logistically demanding field surveys and can help improve the efficiency of UAV-based workflows to support longer-term monitoring in the face of wetland environmental challenges and management constraints. We also highlight several emerging trends in applications, technology, and data and offer insights into future needs.

“…UAV classes, the specification of mounted sensors, flight height and speed may vary according to the aim and specific scope of the research (Watts et al, 2012;Wings et al, 2014;Gülci and Akay, 2016). The UAV-based studies that include before and after the flight stages, should be well designed for the quality of produced photogrammetric data and security (Akgül et al, 2016).…”

ABSTRACT:Unmanned air vehicle systems (UAVSs), which are presently defined as effective measuring instruments, can be used for measurements and evaluation studies in fields. Furthermore, UAVs are effective tools that can produce high-precision and resolution data for use in geographic information system-based work. This study examined a multicopter (hexacopter) as an air platform to seek opportunity in generating DSM with high resolution. Flights were performed in Kahramanmaras Sutcu Imam University Campus area in Turkey. Pre-assessment of field works, mission, tests and installation were prepared by using a Laptop with an adaptive ground control station. Hand remote controller unit was also linked and activated during flight to interfere with emergency situations. Canon model IXSUS 160 was preferred as sensor. As a result of this study, as mentioned previous studies, .The orthophotos can be produced by RGB (Red-green-blue) images obtained with UAV, herewith information on terrain topography, land cover and soil erosion can be evaluated.
