1 US5440916A Emergency response mobile robot for operations in combustible atmospheres A mobile, self-powered, self-contained, and remote-controlled robot capable of safely operating in a surrounding combustible atmosphere and providing information about the atmosphere to the operator. The robot includes non-sparking and non-arcing electro-mechanical and electronic components designed to preclude igniting the combustible atmosphere, and positively pressurized enclosures that house the electro-mechanical and electronic components of the robot and prevent intrusion of the combustible atmosphere into the enclosures. The enclosures are interconnected such that a pressurized gas injected into any one of the enclosures is routed to all the other enclosures through the interconnections. It is preferred that one or more sealed internal channels through structures intervening between the enclosures be employed. Pressure transducers for detecting if the pressure within the enclosures falls below a pre-determined level are included. The robot also has a sensing device for determining the types of combustible substances in the surrounding atmosphere, as well as the concentrations of each type of substance relative to a pre-determined lower explosive limit (LEL). In addition, the sensing device can determine the percent level of oxygen present in the surrounding atmosphere.

The body unit (102) comprises: a battery storage unit (16) to supply power to a lower portion of the upper body (10); a CPU storage unit (20) consecutively formed below the battery storage unit (16); a bracket (14) installed in an outside portion of both sides of the side body (12); and a lower body (30) disposed below the CPU storage unit (20) provided with a mounting part (32). The CPU storage unit (20) comprises a flying control unit (112).  
6 US6701772B2 Chemical or biological attack detection and mitigation system Systems and methods for monitoring buildings to detect harmful chemical or biological agents. Self-propelled harmful agent detectors are provided that can propel themselves using motors and self-contained power sources. On-board harmful agent sensors can detect the presence of harmful agents and transmit information for reception by a receiving unit. Some sensors can identify the type of agent and transmit the agent type. Some detectors can measure the intensity or concentration of the harmful agent presence and transmit that intensity. Some systems include locating devices for determining positions of the roaming detectors, as well as mapping software to map the location of the individual moving detectors. Systems may include software for plotting the relative concentrations of agents detected to locate the origination of the source within the building. The moving detectors can have motors coupled to wheels, tracks, capstans, pulleys and winches to move the devices along floors, air ducts, and suspended or hanging wires.
