A unique drone with a spherical cage won First Place in the UAE's Drones for Good competition.
(GimBall drone)
The entire UAV is effectively a two-prop, electronically stabilized gimball surrounded by a tough, lightweight carbon fiber cage. Instead of trying to avoid obstacles (which is a very difficult feat) the GimBall can just plow right into them, bounce off and then carry on to its destination. It can also roll along the ground or a ceiling.
The cage also protects potential rescue victims from the spinning propellors while making it relatively stress-free to operate indoors. The team sees it as a simple to operate, inexpensive and robust tool for rescuers or industrial inspectors, useful in, say, a nuclear accident or building collapse.
Fans of Stargate may recall this hovering spyball technology.

SF fans may also remember the copseyes from Larry Niven's 1972 story Cloak of Anarchy:
Someone at police headquarters had expected that. Twice the usual number of copseyes floated overhead, waiting. Gold dots against blue, basketball-sized, twelve feet up. Each a television eye and a sonic stunner...
Fans of Steven Spielberg's film Minority Report recall the spider robots, which spread out to search a facility in a mostly autonomous manner. Start the video below at about 1 minutes.
