There are many hazardous environments such as accidents involving fires and chemical, nuclear, or biological contamination which present a need for a robot to travel through them. If these environments are clouded with smoke or fire, then conventional infra-red or visual devices are limited in regards to autonomous navigation. Furthermore, these devices do not directly convey 3-D information about the environment being scanned. To overcome this problem, we present a novel acoustical array imaging system. In the system, acoustical transducers are mounted uniformly on a sphere. By controlling the phase delays of the transducer units, the device can image objects in all directions with no moving parts. The Acoustic Spherical Array Prototype (ASAP) is thus an omni-directional imaging system. To achieve the highest efficiency, its design is an integration of technology, geometric symmetry, and signal processing techniques.
