A rover is teleoperated via the Operator Control Unit (OCU). The physical distance from the operator and the robotic vehicle leads to poor situation awareness and may cause inadequate decision-making. The OCU must be designed wisely to ensure proper human-robot interaction. 17 17 18 - AVAWTthereforewantso measurethepowergenerationandwindvelocityat the testsitewithaSavonius VAWT stylewindturbineduringthemission.Theseturbinesarelightweight,havea simpleconstruction and canbeeasilydeployedandmountedonanearby small hill orevenatthe topof the habitablemodule.To increaseefficiency,anew structuralimprovementof theturbinesisalso beingtested:rectangularopeningsaremadein bothblades andcovered withflexible patches.These patches bend withthewindand allowtheairto flow through theopeningsontheside wherethewind blowsthe blade’s convexsurface.

It addresses two major issues: situation awareness and communication. Unexpected, autonomous action of the robot may cause operator insecurity and influences situation awareness in a negative way. The second challenge deals with communication and communication reliability between the operator and the robot. Issues concerning bandwidth or loss of communication impose constant risks, which need to be mitigated. 19 19 20 - **Independent Experiment:**26 +The expected outcome of the MEROP experiment is an improved teleoperation of robotic vehicles and the implementation of an effective visualization tool that support the flight planning team in the decision-making process. 21 21 22 -* No allocation of GOST/CRW resources or inclusion in mission plan 23 -* Under supervision of GOST CDR 24 -* Eligible for site access 28 +To achieve experiment objectives, the MEROP team will implement a teleoperation interface, where the analog astronaut can choose between two interaction levels: Semi-autonomous teleoperation and direct teleoperation. Semi-autonomous teleoperation features indirect control of the robot using a virtual avatar and interface augmentation techniques. Direct teleoperation allows for the direct control of the robot to enhance situation awareness. 25 25 26 26 27 27 28 - 29 - 30 30 === Experiment Data === 31 31 32 32 (% style="height:10px; width:1000px" %)
