Delft Dynamics B.V. specializes in building small unmanned helicopters for stable, easy to control, aerial sensor-platforms. This is accomplished by intelligently combining computer and sensor technology. Such helicopters can obtain an aerial overview using photos, video cameras and other sensors. Due to their quick deployment capability, robot helicopters can serve police, fire brigades and other emergency services very well. Compared to manned helicopters, robot helicopters have the advantage that they can be deployed from areas very close to the scene of interest. Furthermore, since they are unmanned, they can also be used in potentially dangerous situations.
