Turkish Guard Bot
I just have to admire DIY ingenuity when applied to everyday problems. Take the Turkish farmer in this article over on the Gizmodo site. This poor guy's everyday problem was bears tearing up his crops. What to do? Why, build a scary, noisy, and armed sentry robot of course! This thing is not really all that high tech - it just stumbles around mostly, but apparently bears don't like it. It also does not appear to discriminate what it is scaring (or stunning with electricity), so you may want to keep your distance. At least one problem is solved. Enjoy the video!
