ArduPilot is a software project focused towards providing Trusted, Versatile and Open systems for autonomous, unmanned vehicles. Trusted. ArduPilot aims to be the most open, most tested, most robust system available for unmanned autonomous vehicles. ArduPilot will achieve this by: Employing test and validation regimes for all released software, with test processes and results publicly available; Working with manufacturing Partners to assure appropriate quality of hardware; Engaging with relevant external agencies, in order to understand and shape requirements and expectations for autonomous systems. Versatile. ArduPilot aims to enable autonomous behaviour in any unmanned vehicle, in any environment. ArduPilot will achieve this by: Documenting the current compatible controller hardware, vehicle types, and environmental domains that ArduPilot supports and endorses; Assisting new hardware, novel or different vehicle types, and environmental domains to be added to the ArduPilot codebase; Actively pursuing the limits of technology. Open. ArduPilot supports the development and evolution of open source autonomous technologies, and technologies that support autonomy. ArduPilot achieves this by: Providing publicly available source code; Providing detailed documentation for developers; Working with academia, industry and hobbyists to grow good ideas; Actively assisting new contributors; Providing supported, integrated interfaces into associated hardware and software systems. ArduPilot is a member project of Software in the Public Interest (www.spi-inc.org).
