Abstract:

A major objective in developing tools and weapons for military use has always been ensuring the safety of Soldiers and actively making them aware of hazards in their environment. One such hazard is tripwires hidden in the field. Current research investigates a method of detecting trip wires using an air flow aimed at a wire to generate sound that can then be detected using a microphone. The work presented here examines the effect of varying tension, distance, nozzle type, and air flow rate on the generated sound. Should this technique prove viable, the equipments size would permit usage on small robots. This technique when coupled with other sensors in a multi-modality approach could increase the probability of detection of tripwires.
