Determining vehicle integrity based on observed behavior during predetermined manipulations

A vehicle or another object is grasped by a robotic arm of a handling system and caused to undergo one or more movements or manipulations resulting in a change of position, orientation, velocity or acceleration of the vehicle. Sensors provided in the robotic arm capture data representative of forces or torques imparted upon the robotic arm by the vehicle during or after the movement, or power or energy levels of vibration resulting from the movement. A signature representative of an inertial or vibratory response of the vehicle to the movement is derived based on the data. The signature may be compared to a baseline signature similarly derived for a vehicle that is known to be structurally and aerodynamically sound. If the signature is sufficiently similar to the baseline signature, the vehicle may also be determined to be structurally and aerodynamically sound.
