I have a Foster Miller military Talon 4 tactical robot, they come with new batteries, video remote unit and transport cases.  These are in perfect shape, work up to 2 miles away, can carry up to 100 pounds of cargo and haul 200 pounds.  Faster than a person can run, multiple cameras, weapons release systems etc... these are the real deal.  $5k each firm, batteries alone were $1500, comes with brand new military chargers. These robots were $120,000 NEW!  I am a DOD reseller, these are not allowed outside of the continental US.
