    Every year Asian countries experience significant number of heavy rains, associated flood and landslide disasters. These may cause serious damage of infrastructure and typically result in human casualties. In order to deal with the problems that are caused by such natural disasters we suggest to develop a novel international framework, which targets to provide effective disaster response employing heterogeneous robotic teams and information collection system for a disaster site management. The information collection system targets to become a worldwide standard in the future. In order to test and verify novel concepts and algorithms a proper simulation of a disaster site and robots that are operating within this site are required. In this paper we present preliminary results of simulating a disaster site and a number of robot models in ROS Gazebo environment that are used to test the simulation quality and feasibility from the point of resources and time complexity. The presented models were constructed by the members of our research team and correspond to real robots that are used at LIRS for the project. The models were tested in the simulated environments under a number of pilot protocols for heterogeneous robotic teams' interactions.106-10

    Experimental Validation of an Interface for a Human-Robot Interaction within a Collaborative Task

    This paper presents a prototype of a non-contact UR robot based Vir- tual Control (UR-VC) system for collaborative robots of the UR family, which is based on computer vision techniques and a virtual interaction interface. A control method involved specific hand movements within a field of view of a web cam- era, which was connected to a laptop with the running UR-VC system. We pre- sent the UR-VC system and the results of an experimental validation. To inquire if the UR-VC system is comfortable and user-friendly for an interaction with col- laborative robots and to study opportunities for a further development and expan- sion directions of the system, we designed a test case that simulates a joint prod- uct assembly in a collaborative workspace. The constructed collaborative work- space included the UR3e robot, the laptop with the running UR-VC system and assembly parts for a collaborative task. 24 participants were involved in the ex- periments. First, the participants learned how to control the robot using the UR- VC system. After the training, all participants successfully controlled the robot using the proposed interface for performing the collaborative task. Participants' experience of operating the robot was analyzed via surveys, their unconstrained comments and video recordings of the experiments.23-3
