Abstract: A shock absorbing system for use when landing an unmanned aerial vehicle uses a rocker arm pivotally attached to each landing leg of the vehicle. A strut bracket is attached to each landing leg below the rocker arm. A damper leg is pivotally attached to the rocker arm on one side of the landing leg attachment and the upper end of a damper-loaded strut is pivotally attached to the rocker arm on an opposing side of the landing leg attachment. The base of the strut is fixedly attached to the strut bracket. As the vehicle, it places a downward force on each landing leg which cause the bracket to slide downward along the damper leg, causing the damper leg to pivot its end of the rocker arm upwardly and thus the strut end downwardly causing the strut to compress against the bias of the damper and thereby dampen the landing. Damper leg pairs can be joined by a skid.
