Emergency and disaster situations are unavoidable. Earthquakes, severe weather, bomb threats, and war are an unfortunate reality. Fireﬁghters, bomb technicians, and urban search and rescue specialists are the ﬁrst to respond in emergency situations. These ﬁrst responders risk their lives where remotely operated robots would be more suited for the dangers. Emergency response robots are designed for remote operation implying a wireless connection between the controller and robot. The performance of the wireless communication connection between controller and robot is typically non-ideal. Reﬂective and absorptive properties of the operational environment and interference degrade the communication system limiting range, reliability, and timeliness. An affordable and effective method for evaluating the performance of emergency response robots under speciﬁc attenuated radio conditions is proposed in this paper. The method may be useful for standardization activities currently being pursued by the ASTM International Standards Committee on Homeland Security Applications.
