An arm wearable haptic interface for impact sensing on unmanned aerial vehicles

In this paper, an impact monitoring system using fiber Bragg grating (FBG) sensors and vibro-haptic actuators have been introduced. The system is suggested for structural health monitoring (SHM) for unmmaned aerial vehicles (UAVs), by making a decision with human-robot interaction. The system is composed with two major subsystems; an on-board system equipped on UAV and an arm-wearable interface for ground pilot. The on-board system acquires impact-induced wavelength changes and performs localization process, which was developed based on arrival time calculation. The arm-wearable interface helps ground pilots to make decision about impact location themselves by stimulating their tactile-sense with motor vibration.
