Cable-driven robotic platform systems and methods of operation are disclosed. The system includes a robotic platform suspended by a system of overhead cables, motorized cable reels and pulleys. A master control computer coordinates operation of the motorized cable system as a function of sensor data captured by navigation sensors on-board the platform so as to move the robotic platform inside an industrial plant. The system is configured to maneuver around pipings and avoid obstacles in the plant in order to maximize the effective workspace that the robotic platform can reach to perform operations including inspection or repair. Additionally, a robotic “wire jacket” device can be attached to suspension cables and configured to crawl along a cable. The wire-jacket can be selectively positioned on a cable to provide an intermediate cable suspension point that improves platform mobility within congested spaces and avoids obstacles.

The control unit is configured to send one or more first commands to a plurality of brakes in the articulated arm to begin a release of the plurality of brakes in a predetermined staggered manner, detect a disturbance in a point of interest of the computer-assisted device caused by each brake of the plurality of brakes as the brake is released, and send one or more second commands to the plurality of joints to compensate for the disturbance. In some embodiments, the one or more first commands prevent simultaneous release of two or more brakes of the plurality of brakes. In some embodiments, the one or more first commands cause brakes of the plurality of brakes to release within a predetermined time of each other.
