same reference numbers are used throughout to describe the same material apparatus or process pathway to avoid redundancy detailed descriptions of much of the apparatus once described in relation to a figure is not repeated in the descriptions of subsequent figures although such apparatus or process is labeled with the same reference numbers fig1 is a schematic view of a robotic platform showing the ability for the group of arms to pivot and vary the length of the platform as the robotic platform moves from vertical pipe 1 to 2 to 3 to 4 movement is enabled by a variety of roller grippers having appropriate drive units as well as a pneumatic arm for extending and retracting the slideable portions of the pneumatic arm in addition to pneumatic actuators further gripper means of carrying out the relative movement including screw actuators and an electrical linear slide may also be used as is better seen in reference to fig2 and 3 the roller grippers have a roller gripper motor a gripper base plate gripper fingers finger rollers and gripper sensors the roller gripper drive further includes a drive motor a drive wheel a drive pneumatic cylinder and a mounting plate a robotic platform 10 for navigating across a plurality of vertical pipes 15 is seen in reference to fig2 and 3.
