Human-robot interaction using colored LEDs and custom made hand-held device: a service robot design example

Robots are becoming ubiquitous, going out from production halls with well defined and structured spaces into unstructured spaces where they have to co-exist with humans. This brings into focus human-robot interaction (HRI), especially in the case of mobile service robots. Any misunderstanding of robot’s intents can potentially lead to injury since robots in many cases are large and heavy. Thus, in the paper a simple HRI visualization interface for use with in-house built semiautonomous floor scrubber service robot is proposed. To that end, colored and animated LED strips are used. The LED strips can also help to visualize, in real-time, the performance of algorithm for obstacle avoidance. Additionally, the design and the development of the custom made hand held wireless control unit is presented. The unit uses graphical user interface (GUI) for communication with the operator of the service robot. The software is based on Robot Operating System (ROS). The paper presents details of the design process and initial user and developer experiences. Initial observations are discussed with emphasis on possible improvements in the design.
