Pixhawk
Pixhawk is a project responsible for creating open-source standards for the flight controller hardware that can be installed on various unmanned aerial vehicles. Additionally, any flight controller built to the open standards often includes "Pixhawk" in its name and may be referred to as such. Overview An unmanned vehicle's flight controller, also referred to as an FC, FCB (flight control board), FMU (flight management unit), or autopilot, is a combination of hardware and software that is responsible for interfacing with a variety of onboard sensors and control systems in order to facilitate remote control or provide fully autonomous control. Pixhawk-standardized flight controllers are being used for academic, professional, and amateur applications, and are supported by two mainstream autopilot firmware options: PX4 and ArduPilot. Both firmware options allow for a variety of vehicle types through the Pixhawk flight controller system, including configuration options for unmanne ...

ArduPilot
ArduPilot is an autopilot software program that can control multirotor drones, fixed-wing and VTOL aircraft, RC helicopters, ROVs, ground rovers, boats, submarines, uncrewed surface vessels (USVs), antenna trackers and blimps. ArduPilot was originally developed by hobbyists to control model aircraft and rovers and has evolved into a full-featured and reliable autopilot used by industry, research organisations, amateurs, and militaries—in June 2025 ArduPilot was used successfully by the Ukrainian armed forces during the Russo-Ukrainian War to make aerial drone attacks on Russian air bases. It is published as open source software under the GNU GPL version 3. Characteristics The ArduPilot software suite consists of navigation software (typically referred to as firmware when it is compiled to binary form for microcontroller hardware targets) running on the vehicle (either Copter, Plane, Rover, AntennaTracker, or Sub), along with ground station controlling software including Mi ...

JST Connector
JST connectors are electrical connectors manufactured to the design standards originally developed by J.S.T. Mfg. Co. (Japan Solderless Terminal). JST manufactures numerous series (families) and pitches (pin-to-pin distance) of connectors. JST connectors are used in many types of products, and commonly used by electronics hobbyists and consumer products for rechargeable battery packs, battery balancers, battery eliminator circuits, 3D printers, and radio controlled servos. The term "JST" is sometimes incorrectly used as a vernacular term meaning any small white electrical connector mounted on PCBs. Connector series JST manufactures a large number of series (families) of connectors. The PCB (wire-to-board) connectors are available in top (vertical) or side (horizontal) entry, and through-hole or surface-mount. Soldering A majority of JST through-hole headers can't withstand the temperatures required for reflow soldering, because the plastic has a lower melting point sinc ...

3D Robotics
3DR, also known as 3D Robotics, is an American company located in Berkeley, California that produces enterprise drone software for construction, engineering and mining firms, as well as government agencies. Prior to 2016, the company designed and marketed commercial and recreational unmanned aerial vehicles including consumer drones, ready-to-fly quadcopters for aerial photography and mapping, and fixed-wing UAVs based on the Ardupilot platform. However, as of September 2016, 3DR and the major open source Ardupilot development community separated due to disagreements over the license of the open source code on which 3DR products are based. The company was co-founded as 3D Robotics in 2009 by Chris Anderson and Jordi Muñoz. The pair met online through the ''DIY Drones'' community, which Anderson originally started for aerial vehicle enthusiasts. Products of 3DR Below is a list of products released by 3DR. The Solo Drone was released in May 2015 and marketed to the consumer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MAVLink
MAVLink or Micro Air Vehicle Link is a protocol for communicating with small unmanned vehicle. It is designed as a header-only message marshalling library. MAVLink was first released early 2009 by Lorenz Meier under the LGPL license. Applications It is used mostly for communication between a Ground Control Station (GCS) and Unmanned vehicles, and in the inter-communication of the subsystem of the vehicle. It can be used to transmit the orientation of the vehicle, its GPS location and speed. Packet Structure In version 1.0 the packet structure is the following: After Version 2, the packet structure was expanded into the following: CRC field To ensure message integrity a cyclic redundancy check (CRC) is calculated to every message into the last two bytes. Another function of the CRC field is to ensure the sender and receiver both agree in the message that is being transferred. It is computed using an ITU X.25/SAE AS-4 hash of the bytes in the packet, excluding the Start-of-F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Vision
Computer vision tasks include methods for image sensor, acquiring, Image processing, processing, Image analysis, analyzing, and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e.g. in the form of decisions. "Understanding" in this context signifies the transformation of visual images (the input to the retina) into descriptions of the world that make sense to thought processes and can elicit appropriate action. This image understanding can be seen as the disentangling of symbolic information from image data using models constructed with the aid of geometry, physics, statistics, and learning theory. The scientific discipline of computer vision is concerned with the theory behind artificial systems that extract information from images. Image data can take many forms, such as video sequences, views from multiple cameras, multi-dimensional data from a 3D scanning, 3D scanner, 3D point clouds ...

LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, and is therefore also referred to as 3.95G as a step above 3G. LTE is based on the 2G GSM/ EDGE and 3G UMTS/ HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. LTE has been succeeded by LTE Advanced, which is officially defined as a "true" 4G technology and also named "LTE+". Terminology The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as 4G LTE and Advanced 4G; but the original version did not meet the technical criteria of a 4G wire ...

Ethernet
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses a thick coaxial cable as a shared medium. This was largely superseded by 10BASE2, which used a thinner and more flexible cable that was both less expensive and easier to use. More modern Ethernet variants use Ethernet over twisted pair, twisted pair and fiber optic links in conjunction with Network switch, switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the lates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery Management System
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), calculating secondary data, reporting that data, controlling its environment, authenticating or balancing it. Protection circuit module (PCM) is a simpler alternative to BMS. A battery pack built together with a BMS with an external communication data bus is a smart battery pack. A smart battery pack must be charged by a smart battery charger. Functions Monitor A BMS may monitor the state of the battery as represented by various items, such as: * Voltage: total voltage, voltages of individual cells, or voltage of * Temperature: average temperature, coolant intake temperature, coolant output temperature, or temperatures of individual cells * Coolant flow: for liquid cooled b ...
