Home monitoring system based on indoor service robot and wireless sensor network

•Robot is combination of mobile sensing, wireless communication and execution module.•The wireless sensor node contains the mote module and the sensor board.•Construct the wireless sensor network based on self-organizing feature map model.•Location algorithm of indoor service robot is based on wireless sensor network.•Robot can improve network flexibility and system capability to handle emergency.

In this paper, the design and implementation of a home monitoring system which is based on indoor service robot and wireless sensor network are presented. The wireless sensor node which consists of mote module and sensor board is designed and fabricated. The construction algorithm of the wireless sensor network is based on self-organizing feature map model. The indoor service robot which has the capabilities to follow human commands and handle emergency is designed and implemented. A location algorithm of the robot based on the wireless sensor network is proposed. Stability of the proposed home monitoring system in longtime monitoring tasks is tested. Experimental results also demonstrate the indoor service robot can improve the capabilities of the wireless sensor network and the home monitoring system.
