Communication Scheme of Cloud Platform for the Lower Limb Exoskeleton Rehabilitation Robot

In this paper, a communication scheme of cloud platform for the lower limb exoskeleton robot is proposed. Firstly the wireless communication protocol Zigbee is used to build a sensor network to collect and summarize sensors' data of users' physiological information and robot movement. Secondly, Message Queuing Telemetry Transport (MQTT) is used to transmit the data into the cloud platform for data preservation and processing. Finally, the cloud platform is accessed remotely to obtain the physiological information of the user and robot movement based on the HyperText Transfer Protocol (HTTP). Experiments indicate its effectiveness and practicability of the proposed communication scheme to present sensors data to users or doctors in Web pages.
