A novel approach to vibration isolation in small, unmanned aerial vehicles

Abstract

Small accelerometers currently used in ground, robotic platforms measure inclination of vehicles and positions of actuators. However, the vibration of aerial vehicles due to rotors makes them it impracticable. The sensor cannot provide the precision necessary to control an aerial platform and distinguish between vibration and inclination. An isolator that is configurable, lightweight and axis-independent would be advantageous. Tempurpedic <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">reg</sup> foam provides these capabilities and initial tests have resulted in over a 50% reduction in measurement error. This can lead to improved aerial control and performance, making the impracticable, practicable again. Furthermore, improved autonomous flight that is less dependent on human interaction and skill becomes more plausible. Small unmanned aerial vehicles, especially helicopter-type, can provide some significant advantages and capabilities where an unmanned ground vehicle is unsuitable, impracticable or limited.
