Vacuum traction device

A system for performing work on an inclined surface of a structure, the system comprising:

• a support robot suitable for positioning at a high point on the structure on or near the inclined surface, the support robot including at least one traction device to permit the support robot to cling to and maneuver along the inclined surface;
• a payload robot including a tool for performing a desired function with respect to the inclined surface, the payload robot including at least one traction device to permit the payload robot to cling to and maneuver along the inclined surface;
• a tension element for connecting the payload robot to the support robot such that the support robot provides support to the payload robot;
• and
• a control mechanism for controlling movement of the payload robot and the support robot.

A method of performing maintenance on an inclined surface of a structure comprising:

• providing a support robot suitable for positioning at a high point on the structure on or near the inclined surface, the support robot including at least one traction device to permit the support robot to cling to and maneuver along the inclined surface;
• maneuvering the support robot to the high point on the structure;
• providing a payload robot including a tool for performing a desired function with respect to the inclined surface, the payload robot including at least one traction device to permit the payload robot to cling to and maneuver along the inclined surface;
• attaching the payload robot to the support robot with a tension element;
• and
• maneuvering the payload robot to a desired working position on the inclined surface.
