The latest anti-poaching tool may not be as completely bizarre as the Robodeer, but the TrailGuard technology coming out of Steve Gulick's laboratory is entirely more sophisticated (and stealthy, too). The system consists of a network of metal detectors buried next to forest trails which will detect the presence of a contraband machete or rifle and swing into action. Upon recognizing a potential weapon, the sensor will "send a radio signal to a nearby internet gateway and then to the internet via satellite," which will subsequently alert a ranger to the unwanted guest practically in real-time. The developing team insinuates that this product could make the rounds that rangers make a lot more efficient, and considering that most national parks are somewhat understaffed, this could help them cover the ground that they need to. So if you just so happen to wander out in the woods and pitch a tent with metal stakes, only to be approached by an armed wildlife officer, don't be too alarmed.
