Militaries, law enforcement, and more around the world are increasingly turning to robot dogs " which, if we're being honest, look like something straight out of a science-fiction nightmare " for a variety of missions ranging from security patrol to combat. Robot dogs first really came on the scene in the early 2000s with Boston Dynamics' "BigDog" design. They have been used in both military and security activities. In November, for instance, it was reported that robot dogs had been added to President-elect Donald Trump's security detail and were on patrol at his home in Mar-a-Lago. Some of the remote-controlled canines are equipped with sensor systems, while others have been equipped with rifles and other weapons. One Ohio company made one with a flamethrower. Some of these designs not only look eerily similar to real dogs but also act like them, which can be unsettling. In the Ukraine war, robot dogs have seen use on the battlefield, the first known combat deployment of these machines. Built by British company Robot Alliance, the systems aren't autonomous, instead being operated by remote control. They are capable of doing many of the things other drones in Ukraine have done, including reconnaissance and attacking unsuspecting troops. The dogs have also been useful for scouting out the insides of buildings and trenches, particularly smaller areas where operators have trouble flying an aerial drone.
