Caves- no I don’t think so, rather sophisticated urban warfare and in any case it is deadly sophisticated designed smaller craft.
These smaller craft, as I also did found out in my PhD study on DEW some time ago, are developed with the urban warfighter in mind. DEW in this case literally means speed- of light.
1. Laser-range finders
2. Miniature laser-guided missiles
3. Sophisticated IR video surveillance
4. Sophisticated software already developed to do area-control and to fly autonomously in a pre-programmed sequence – which you may find strange but these craft can do it.
5. Loitering over a designated target is also included, as these can be used to target specific persons-of interest.
Thank you for pointing that one out - I was originally going to use that from TED - but decided on the other two to emphasize the "aggressive maneuvers"[sound more military]. Last year while lecturing I came across the latter - as I do lecture robotics, and it was very good and only now that i decided to upload again something - it was the latter two.
Depends on what you want to do with it. You can develop a monitoring loop in your software to check - and also how you are going to use it. Remember the devices are designed to be use din a covert surveillance/ covert strike usage and that implies that it will sit still as well only to observe via on-board cameras.
