Star Wars fans (like me) will get a vague sense of deja vu when they see this flying sphere in action. Weighing in at about 12 ounces (350 g), the 16-inch (42 mm) diameter flying ball can launch and return vertically, maintain a stationary hover and zip along at up to 37 mph (60 km/h). Coupled with the ball camera we reported on earlier this month, it could become a valuable reconnaissance platform. Who knows? In time, more advanced autonomous versions might actually be used to train would-be Jedi knights. Once again, life imitates art.Announced last summer by the Technical Research and Development Institute at Japan's Ministry of Defense (JMD) and recently unveiled at Digital Content Expo 2011, the world's first spherical air vehicle will likely be deployed in search and rescue operations deemed unsuitable for traditional aircraft. As for other possible uses, the sky just may be the limit.
"Because the exterior is round, this machine can land in all kinds of attitudes, and move along the ground. It can also keep in contact with a wall while flying. Because it's round, it can just roll along the ground, but to move it in the desired direction, we've brought the control surfaces, which are at the rear in an ordinary airplane, to the front," said a JMD spokesperson.
For something that looks so ungainly, the rig exhibits surprising stability. Thanks to three onboard gyro sensors, the device effectively maintains its orientation and altitude, even after collisions. Numerous control surfaces also assist with attitude control. The current prototype, which cost about US$1,400 in parts, can maintain a hover for a respectable eight minutes. Now, if only someone would perfect that light saber we've all been waiting for.
