Unmanned Tunnel Exploitation

Tunnels are an increasing problem for securing the borders. Due to hazards inherent in assessing these tunnels, robotic reconnaissance would play an important role in gathering vital information regarding tunnel use and closure logistics. Since conventional robotics platforms do not meet the threat needs, the unmanned tunnel exploitation (UTE) research used numerical simulation and experimentation to determine the optimal platform to help overcome identified technology shortfalls by addressing mission specific tasking for autonomous navigation intelligence. To refine the tunnel mission specific behaviors for UGVs, in December, 2008, testing was performed through a border tunnel in Douglas, AZ with the INL RIK laser mapping capability and associated semi-autonomous behaviors on a Foster-Miller Talon robot. The laser mapped data combined with video provided a more complete situational awareness for robot operator. In March 2009, the untethered radio communications of the Talon were evaluated in a metal-reinforced tunnel complex.
