It seems like the folks over at the Flying Machine Arena are finally starting to catch on -- those quadrocopters are going to kill us all. Thankfully, after teaching them to juggle and tap out some tunes , the researchers came to their senses and put the flying machines on a Kinect-controlled leash. Instead of flitting about autonomously , the four-rotored nightmares are directed by a puppeteer waving his hands. Movement is controlled by the right hand, while raising the left one tells the copter to do a little flip for its master's amusement, and a commanding clap makes it sit down like a good little pup. Best of all, if you don't give it any arm-waving instruction it just hovers and waits until you tell it otherwise. On further consideration, maybe we haven't been creating our own murderers, but a new man's best friend -- after all, they don't eat much and can't chew up your remotes. Check out the video after the break.
