Clear, unjittered pictures and film shooting best succeed with the use of a tripod. Even if only taking photos whilst moving slowly, the picture may appear unclear. The distortion becomes more extreme if the camera is mounted in a vehicle or even an aeroplane. Photographic devices rely on additional stabilization especially in small aeroplanes as they provide little automatic damping due to their low permanent weight. Here, a gimbal-mounted, gyro-stabilized mounting platform is a perfect solution. However, weight is an issue, simply because the mini aeroplane or reconnaissance drone still has to be able to take off. Micromotors with adapted transmissions provide the solution for easy, reliable gyro-stabilization.
The use of unmanned aerial vehicles (UAVs), also known as drones, is often favoured in the military field to exercise the dangerous job of reconnaissance. One drone costs 2 to 5 million euros. However, smaller light and ultra-light drones can be acquired for much less – a few tens of thousands up to one hundred thousand euros. This is why other users such as cartographers, archaeologists and various industrial exploration concepts increasingly rely on these flexible reconnaissance planes. Unfortunately, the combination of small size and good value also translates into a low load capacity. Apart from the camera, the most important component for clear photos during a flight is the stabilized mounting platform. Normal stabilizers based on gyro-stabilization are too heavy for small aircraft. The Hood Technology Corporation, from Hood River in Oregon, USA, has developed a new lightweight design for this specific purpose. In cooperation with the drive specialist MicroMo, the North American FAULHABER Group company, it was possible to adapt gyro-stabilization for UAVs.
