ORCA is an open-source framework for developing component-based robotic systems. The framework offers a way for defining and developing the building-blocks and for piecing together the building blocks to form arbitrarily complex robotic systems, from single vehicles to distributed sensor networks. The project offers a software component library (called hydro) of open source algorithms and drivers, in addition to the ORCA framework that uses Hydro components and ICE for component communication.
