<p>PURPOSE:To enable the approach time of a robot to a distribution line, to be shortened, by driving one shaft among the three shafts of a wrist for fitting a working tool, with a driving means, and by rotating or fixing the two residual shafts freely by a flexible means. CONSTITUTION:At the tip of an automatic arm 36 mounted on a high-place service car, a wrist 39 with a fitted working tool 30 is set to form a hot-line work robot. The wrist 39 is set to be of a driving system with three shafts, and so far as one of the shafts is concerned, a driving means 40 for power driving is set in the wrist 39. The two residual shafts are contrived to be supported by a flexible means 50 which can freely rotate or fix the shafts. As a result, in any direction to a distribution line 1, the approach of the working tool 30 to the distribution line 1 can be easily executed, and the time of the approach can be shortened.</p> |
