In the Future, Flying Donuts May Guide Us

It's a common scene at a big office -- a gaggle of visitors lost in a maze of corridors and rooms, plaintively asking for directions to a meeting.
In the future they might be greeted at reception and simply told: "Follow the floating donut," The (Sydney) Daily Telegraph reported Wednesday.
Just such a machine -- known as a blimp -- has been built to show people around buildings at Australia's Commonwealth Scientific and Industrial Research Organization (CSIRO).
The indoor blimp is a modified party balloon, the work of avionics engineering student Bryan Huang.
The 3-foot-wide blimp cruises the corridors using three propellers for lift and forward thrust and a number of infrared sensors to detect obstacles and walls.
A pressure sensor, accelerometer and compass detect height, speed and direction. For navigation, the blimp also uses a wireless sensor network.
Sensor nodes are scattered throughout CSIRO's Queensland Center for Advanced Technologies complex in Brisbane, where the blimp is being tested, to help guide it around the building.
