Abstract

A unified system for development of robotics and other cyber-physical systems is discussed. The unified system includes a platform that integrates the processing of actuators and sensors and other modules. The platform is inter-operable into many existing systems. Various modules are developed to do discrete tasks that are commonly found in robotics such as moving motors or reading and controlling sensors. The modules communicate with each other and with other devices such as computers and user built modules through the use of a commonly supported abstract communication protocol.
