Abstract
In order to prevent disasters or crimes as few as possible, or minimize the damage even if they occur, quick information gathering system for search and surveillance is required. An indoor blimp robot has the excellent information gathering capability and can perform three-dimensional movement. The indoor three-dimensional robot which is very close to men should be safe, quiet, and non-annoying. The blimp satisfies these properties perfectly. In this paper, a flexible switching system between manual operation and automatic operation through computers is developed. The automatic control system is constructed by tracking markers on a blimp from a pan-tilt camera on ground and estimating the position.
