Since the ancient days of agriculture, man has struggled to protect his crops from hungry avian intruders. Today, farmers can turn to high-tech devices equipped with motion sensors and water cannons to keep pesky birds from pillaging their land. And while a pumpkin-headed scarecrow may be an agricultural anachronism, it’s also a tried-and-true security system. In the spirit of Halloween, PM examined some impressive takes on the old classic.
In 2006 a team of undergrads at the University of South Florida developed a robotic scarecrow intended to protect Florida’s fish farms from wading birds. The “Intelligent Scarecrow” used a micro-PC and surveillance camera to detect incoming poachers, and was programmed to discriminate between intruders and farmers. Assuming that farmers were wearing an orange vest, the team developed the system to recognize the color. If something not colored orange enters into a 40-foot range, water cannons are triggered, as is a series of prerecorded hawk screams and gun blasts. The PC then sends an SMS text message and email to the farmers, alerting them of possible security breaches. To complete this truly DIY project, the students outfitted their creation in a USF football jersey and helmet before taking second place in Microsoft’s 2006 Windows Embedded Student Challenge.
