摘要：A critical challenge in telerobotic system is data communication over networks without performance guarantee. This paper proposes a novel way of using auditory feedback as the sensory feedback to ensure that the teleoperated robotic system still functions in a real-time fashion under the unfavorable communication conditions, such as image losses, visual failures, and low-bandwidth communication links. The newly proposed method is tested through psychoacoustic experiments with 10 subjects conducting real-time robotic navigation tasks. The performance is analyzed according to an objective point of view (time to finish task, distance away to the target measurements), as well as subjective workload assessments for different sensory feedbacks. Moreover, the bandwidth consumed when auditory information is applied is considerably lower, compared with the visual information. Preliminary results demonstrate the feasibility of auditory display as a complement or substitute to visual display for remote robotic navigation.
