ZigBee based wireless sensor networks for service robot intelligent space

This paper is concerned with the implementation of ZigBee based wireless sensor networks, which has been applied in our service robot intelligent space successfully. A simplified ZigBee stack is proposed and the primitives of simplified ZigBee based wireless sensor networks are illustrated, which reduces the stack, thus the storage, size and cost of the nodes was brought down. To show the functionality of the ZigBee based wireless sensor networks in service robot intelligent space, we describe some of the components in detail, such as environmental sensors for environmental perception, home devices controllers for device control, localization system for positioning and ceiling projector for mobile robot navigation. Finally, we conclude this paper and the direction of future research are given.
