The main goal of the RETA Project is to study, develop and implement an Ambient Intelligence environment in the context of a specific room inside a house, in order to perform assistive tasks. The system will be composed of a set of distributed sensors (e.g. cameras, microphones), robots (e.g. humanoid robots, mobile manipulators) and other devices (e.g. touchscreens, domotic devices) of different types, all of them integrated in a networked intelligent environment in order to provide assistance in a individualized or synchronized manner. This distributed system, composed of robotic and domotic devices, will be internally connected through a custom network protocol known as SNRP (Siple Network Robot Protocol). This will allow that different robots can be easily connected to the system in a scalable and dynamic manner.
