Rancang Bangun Sistem Foto Udara Menggunakan Layang-Layang (Kite Aerial Photography)
Kite aerial photography (KAP) provides an alternative solution on conventional aerial photography by using kite equipped with digital camera that can be controlled from the ground and that can stream video to the ground. Data communication system that is applied on KAP utilizes microcontroller AT89S52 as the interface. Commands from a non-vibrated play station stick are modullated using frequency shift keying (FSK) and transmitted from the ground to the KAP. The commands are then demodullted for controlling the shutter and zoom of digital camera and positioning the digital camera by rotating servo motor (panning and tilting). Video is transmitted using frequency 1.2 GHz and received by a TV tuner to view the location/obejct to be captured. Functional testing has been conducted and resutls suggest that the system works as expected
CQAR: Closed quarter aerial robot design for reconnaissance, surveillance and target acquisition tasks in urban areas
International Journal of Computational Intelligence, Volume 1, Number 4, 2004. Retrieved April 2006 from http://prism2.mem.drexel.edu/~paul/papers/ohIjci2004.pdfThis paper describes a prototype aircraft that can fly
slowly, safely and transmit wireless video for tasks like reconnaissance,
surveillance and target acquisition. The aircraft is designed to
fly in closed quarters like forests, buildings, caves and tunnels which
are often spacious but GPS reception is poor. Envisioned is that a
small, safe and slow flying vehicle can assist in performing dull,
dangerous and dirty tasks like disaster mitigation, search-and-rescue
and structural damage assessment

Review article: The use of remotely piloted aircraft systems (RPASs) for natural hazards monitoring and management
The number of scientific studies that consider possible applications of remotely piloted aircraft systems (RPASs) for the management of natural hazards effects and the identification of occurred damages strongly increased in the last decade. Nowadays, in the scientific community, the use of these systems is not a novelty, but a deeper analysis of the literature shows a lack of codified complex methodologies that can be used not only for scientific experiments but also for normal codified emergency operations. RPASs can acquire on-demand ultra-high-resolution images that can be used for the identification of active processes such as landslides or volcanic activities but can also define the effects of earthquakes, wildfires and floods. In this paper, we present a review of published literature that describes experimental methodologies developed for the study and monitoring of natural hazard
The Role of Vision Algorithms for Micro Aerial Vehicles
This work investigates the research topics related to visual aerial navigation in loosely structured and cluttered environments. During the inspection of the desired infrastructure the robot is required to fly in an environment which is uncertain and only partially structured because, usually, no reliable layouts and drawings of the surroundings are available.
To support these features, advanced cognitive capabilities are required, and
in particular the role played by vision is of paramount importance. The use
of vision and other onboard sensors such as IMU and GPS play a fundamental to
provide high level degree of autonomy to flying vehicles. In detail, the outline of
this thesis is organized as follows
• Chapter 1 is a general introduction of the aerial robotic field, the quadrotor
platform, the use of onboard sensors like cameras and IMU for autonomous
navigation. A discussion about camera modeling, current state of art on vision
based control, navigation, environment reconstruction and sensor fusion
is presented.
• Chapter 2 presents vision based control algorithms useful for reactive control
like collision avoidance, perching and grasping tasks. Two main contributions
are presented based on relative depth map and image based visual
servoing respectively.
• Chapter 3 discusses the use of vision algorithms for localization and mapping.
Compared to the previous chapter, the vision algorithm is more complex
involving vehicle’s poses estimation and environment reconstruction. An algorithm
based on RGB-D sensors for localization, extendable to localization
of multiple vehicles, is presented. Moreover, an environment representation
for planning purposes, applied to industrial environments, is introduced.
• Chapter 4 introduces the possibility to combine vision measurements and
IMU to estimate the motion of the vehicle. A new contribution based on Pareto Optimization, which overcome classical Kalman filtering techniques,
is presented.
• Chapter 5 contains conclusion, remarks and proposals for possible developments
