Abstract： In the distributed environment, robots should be able to provide user s with adaptive services automatically according to the situational information changing dynamically which is obtained from both users and their environments. T he workflow depends on situational information obtained from physical environmen ts and provides context-aware services automatically based on the information re trieved. And the workflow in the business processes and the distributed computin g environments have supported the automation of services by connecting tasks. T he workflow needs to specify ubiquitous situational information as state-transit ion constraints. However, the delivery and use of sensor data in the workflow is a difficult problem for the robot system. In order to bridge the gap between ap plications and low-level constructs and to acquire raw situational information f or the execution of the context-aware workflow in the robot systems, this paper presents an approach which can achieve the sensor data transmission between a se nsing server and a robot system easily.
