Gardner Psychiatric Hospital was hardly in some remote wilderness, and both the Venom Car and the Spider-Shaped Predator units could serve as signal relays, so communications were not a concern.
As the twelve Spider-Shaped Predators entered the woods, video feeds soon began coming back from each of them.
Remote operation beyond his line of sight required switching back and forth between feeds, greatly reducing the flexibility of brainwave control and making fine maneuvers extremely difficult.
Fortunately, the Spider-Shaped Predators were robots, after all. Even without brainwave control, they had their own intelligent systems, so directing them to move and search through basic commands was still no problem.
Living creatures tended to be extremely sensitive to "facial features." As long as something had a roughly recognizable combination of eyes, ears, mouth, and nose, even if it was only a few indistinct holes, creatures could usually recognize it at a glance in all sorts of complex environments.
This was an instinctive response that had evolved through survival of the fittest. Facial features often meant life, and in the wilderness, they could also mean a hidden predator.
The Spider-Shaped Predators were not living creatures, of course, but their targeting systems contained similar image-processing modules. In the complex woodland environment, any image containing elements of facial features would trigger an alert and further identification before ultimately being sent to Xia Xu's Smart Glasses terminal.
Xia Xu quickly browsed through these images, manually eliminating most of the false positives and Mountain Search Personnel before finally stopping on an image sent back by Spider-Shaped Predator 08.
In fact, he had skipped straight past this image on his first look, because it did not show a complete set of facial features, only two dark holes in the treetop.
The holes were also rather large and widely spaced,
