Abstract: Various embodiments of a system and method for reducing vibrations in and inspecting a suspended cable are described. In one embodiment, a vibration control robot includes a frame roller cage configured to roll open and closed around a cable, a drive system comprising a motor system to maneuver the robot along the cable, and a vibration absorption system to admit and absorb mechanical vibrations from the cable. The vibration absorption system can include a messenger cable segment of a predetermined length, where the messenger cable segment is mechanically coupled with the frame to admit mechanical vibrations on the cable. The vibration absorption system can also include an absorbing counterweight tip mass, a sliding mass, and a permanent magnet of an electromagnetic transducer device, to convert the mechanical vibrations in the messenger cable into electrical energy.
