A robot that is equipped with an audio device can prove to be especially useful in the gathering of information in potentially hazardous areas. For example, a police robot with microphones and a two-way audio system can enable authorities to communicate with suspects or hostages. These robots can be very useful in negotiation situations because they would not present a threat to suspects.

They can also continue to gather information while the police are using the audio system to communicate with those in dangerous situations. Furthermore, these robots can also be used to deliver items like food to victims without risking the life of a police officer during hostage takings.
