Some years ago, a sweet grandma in my (Christine's) neighborhood was convinced that one of her neighbors was involved in illegal activity. Although my husband and I tried to assuage her overactive mind, she insisted we purchase and deliver binoculars to enable her to perform her civic duty as a self-appointed sleuthhound. If it had been this year, she could have placed an order on-line and a drone could deliver the packaged binoculars to her front door . Perhaps next year, she can trade in the binoculars for a perching air drone that will not only fly, but also perform a controlled stall with actuators allowing the feet to grip the branch of the tree in her neighbor's yard. The bird-like drone, with motors that can shut down to avoid energy depletion, can sit for long periods of time, recording lots and lots of data .
