Autonomous Aircraft
An autonomous aircraft is an aircraft which flies under the control of automatic systems and needs no intervention from a human pilot. Most autonomous aircraft are unmanned aerial vehicle or drones. However, autonomous control systems are reaching a point where several air taxis and associated regulatory regimes are being developed. History Unmanned aerial vehicles The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, serving as a balloon carrier (the precursor to the aircraft carrier) Significant development of radio-controlled drones started in the early 1900s, and originally focused on providing practice targets for training military personnel. The earliest attempt at a powered UAV was A. M. Low's "Aerial Target" in 1916.Taylor, John W. R.. ''Jane's Pocket Book of Remotely Piloted Vehicles''. Autonomous features such as the autopilot and automated navigation were developed progressively through the twentieth century, although techni ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Engine
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which he ...

ArduCopter
ArduPilot:Copter previously named APM:Copter or ArduCopter is the multicopter unmanned aerial vehicle version of the open-source ArduPilot autopilot platform. The free software approach from ArduCopter is similar to that of the Paparazzi Project and PX4 autopilot where low cost and availability enables its hobbyist use in small remotely piloted aircraft such as micro air vehicles and miniature UAVs. Original Unboxing ArduCopter by Chris Anderson by Jani Hirvinen and his team at DIYDrones was released in August 2010. See also *Open-source robotics *Crowdsourcing *Micro air vehicle A micro air vehicle (MAV), or micro aerial vehicle, is a class of miniature UAVs that has a size restriction and may be autonomous. Modern craft can be as small as 5 centimeters. Development is driven by commercial, research, government, and mil ... References {{Reflist Unmanned helicopters Open-source hardware Arduino ...

Xenomai
Xenomai is a real-time development software framework cooperating with the Linux kernel to provide wikt:pervasive, pervasive, interface-agnostic, hard real-time computing support to user space application software seamlessly integrated into the Linux environment. The Xenomai project was launched in August 2001. In 2003, it merged with the Real-Time Application Interface (RTAI) project to produce RTAI/fusion, a real-time free software platform for Linux on Xenomai's abstract real-time operating system (RTOS) core. Eventually, the RTAI/fusion effort became independent from RTAI in 2005 as the Xenomai project. Xenomai is based on an abstract RTOS core, usable for building any kind of real-time interface, over a nucleus which exports a set of generic RTOS services. Any number of RTOS personalities called “skins” can then be built over the nucleus, providing their own specific interface to the applications, by using the services of a single generic core to implement it. Xenomai v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NuttX
NuttX is a free and open-source Real-Time Operating System (RTOS) with an emphasis on technical standards compliance and on having a small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the main governing standards in NuttX are from the Portable Operating System Interface (POSIX) and the American National Standards Institute (ANSI). Further standard application programming interfaces (APIs) from Unix and other common RTOSes (such as VxWorks) are adopted for functions unavailable under these standards, or inappropriate for deeply embedded environments, such as the fork() system call. NuttX was first released in 2007 under the permissive BSD license. Since December 2019, it has been undergoing incubation at the Apache Software Foundation. Usage NuttX RTOS is used in a variety of applications, including the Sony CXD5602/Spresense microcontroller as well as an audio recorder from Sony. The firmware for some of Motorola's MotoMod accessories for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BeagleBoard
The BeagleBoard is a low-power open-source single-board computer produced by Texas Instruments in association with Digi-Key and Newark element14. The BeagleBoard was also designed with open source software development in mind, and as a way of demonstrating the Texas Instrument's OMAP3530 system-on-a-chip. The board was developed by a small team of engineers as an educational board that could be used in colleges around the world to teach open source hardware and software capabilities. It is also sold to the public under the Creative Commons share-alike license. The board was designed using Cadence OrCAD for schematics and Cadence Allegro for PCB manufacturing; no simulation software was used. Features The BeagleBoard measures approximately 75 by 75 mm and has all the functionality of a basic computer. The OMAP3530 includes an ARM Cortex-A8 CPU (which can run Linux, Minix, FreeBSD, OpenBSD, RISC OS, or Symbian; a number of unofficial Android ports exist), a TMS320C64x+ DS ...

Raspberry Pi
Raspberry Pi () is a series of small single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. The Raspberry Pi project originally leaned towards the promotion of teaching basic computer science in schools and in developing countries. The original model became more popular than anticipated, selling outside its target market for uses such as robotics. It is widely used in many areas, such as for weather monitoring, because of its low cost, modularity, and open design. It is typically used by computer and electronic hobbyists, due to its adoption of the HDMI and USB standards. After the release of the second board type, the Raspberry Pi Foundation set up a new entity, named Raspberry Pi Trading, and installed Eben Upton as CEO, with the responsibility of developing technology. The Foundation was rededicated as an educational charity for promoting the teaching of basic computer science in schools and developing co ...
