Here is a robotic Ghost Dog designed to limit human exposure to potential dangers. This semi-autonomous 4-legged robot can take on inspection, perimeter security, and patrolling. These robotic dogs can be enhanced with communication, robotic arm, and other attachments.
These dogs can patrol 7.5 miles of space on a single charge. They return to a wireless charging doghouse when they need more juice. The above video shows how these robot dogs can be used by the Air Force.
