i think it can be used for police operations instead of dogs in SWAT situations like this for example http://www.dailymail.co.uk/news/article-3323495/Hero-police-...
Amusing note: at least for ATF, all arson/explosives detection dogs are dropouts from the seeing eye dog training programs (too energetic). Source: relative was involved with the program.
i specifically mentioned SWAT missions. This is where a robot can replace the dog or man "on the point". It just have to enter the room/etc. and burn several flash grenades, even without throwing them :) After that real people&dogs may enter much more safely.
