Paper Abstract

The focus of this study is the application of teleoperation to live-line maintenance work on power distribution lines. The research team's objectives are to measure and compare human performance, the levels of mental workload and the degree of satisfaction corresponding to three working techniques: the hot-stick technique (S), the direct-vision teleoperation technique with and without force feedback (T1 and T2, respectively) and the ground-level teleoperation technique (G). Three linemen with substantial experience with S, little experience with T1 and none with T2 or G took part in a study in which they had to perform a typical task with each of the three techniques. The results show that, compared to S, the productivity ratios for teleoperation are approximately 0.6 for T1, 0.5 for T2 and 0.3 for G. Extrapolation of the results shows that these productivity levels will increase with practice but not to the point where the teleoperation techniques would be as rapid as the hot- stick technique. Technical improvements in the near future are expected to help increase these ratios. The mental workload is higher with T2 and G than with S and T1. Lastly, T1 is the preferred technique and T2 the least appreciated.
