This paper is concerned with the design and implementation of a ZigBee based wireless sensor and actuator networks, which has been applied in our service robot intelligent space successfully. Firstly, an overview of ZigBee protocol is given, and then the design and implementation of hardware module and software stack of ZigBee based wireless sensor and actuator networks are addressed in detail. Some representative devices are described, including environmental sensors for environmental perception, home devices controllers for device control, IMU module for abnormal behaviors detection, locating system for node localization and laser robot control for service robot navigation. Application example is described to demonstrate how the devices in ZigBee based wireless sensor and actuator networks to provide service cooperatively. Finally, we conclude this paper and discuss the future directions.

A quad, small form-factor pluggable 28 Gbps optical transceiver design scheme is proposed. It is capable of transmitting 50 Gbps of data up to a distance of 40 km using modulation signals with a level-four pulse-amplitude. The proposed scheme is designed using a combination of electro-absorption-modulated lasers, transmitter optical sub-assembly, low-cost positive-intrinsic-native photodiodes, and receiver optical sub-assembly to achieve standard performance and low cost. Moreover, the hardware and firmware design schemes to implement the optical transceiver are presented. The results confirm the effectiveness of the proposed scheme and the performance of the manufactured optical transceiver, thereby confirming its applicability to real industrial sites.
