When you picture a consumer drone, something bulky with four or six props à la DJI probably pops to mind. But the folks behind a new model on Kickstarter think that such UAVs have two big problems -- namely, they're hard to carry and break easily if you mess up. They built The Sprite to overcome those limitations with a cylindrical, waterproof body and retractable blades. The design makes it easy to throw it into a pack, and when landing, the rotors halt in a half a second and fold into a retracted position. From there, the craft can safely alight on rocks, a bush or even a swamp without issues.
