Patent ID: 8490505

Claim:
A robot mechanism for nondestructive aging evaluation of a cable, comprising: at least two inspection modules, each approaching a cable and automatically inspecting an aged state of the cable, wherein each of the inspection modules includes: a body assembled by a fastener; a transfer unit coupled to a lower portion of the body and moving along the cable; and a measurement unit disposed at a center of the lower portion of the body to perform measurement and inspection of a local aged state of the cable, wherein the measurement unit includes: a drive motor secured to the lower portion of the body; a rotational shaft connected to an upper portion of the drive motor and driven by transmitted power; a drive gear connected to the rotational shaft to be associated with rotation of the rotational shaft; a driven gear engaging with the drive gear; a cylinder converting the rotation of the rotational shaft into up-down movement; a force sensor provided to a lower portion of the cylinder to measure or control a force generated by the cylinder; and an indentation needle provided to a lower surface of the force sensor to contact the cable; and a coupler disposed between the at least two inspection modules and connected to each of the inspection modules to adjust a separation between the inspection modules.
