Abstract:The EspeleoRobô is a teleoperated mobile robotic platform employed by the mining company Vale S.A. to explore confined environments. During inspection operations, it is common for the robot to encounter adversities, including loss of connection with the control base. This article focuses on the robotic device communication system, describing communication problems via radio signal and introducing signal strength decay models. Furthermore, we present command strategies for orienting directional antennas install… Show more
