1. A robotic arm comprising:
- a first end connected to a first end effector;
a second end connected to a second end effector; and
at least one joint moveably connecting the first end and the second end for movement in a plurality of axes on a surface;
wherein the first end effector comprises a foot;
wherein the second end effector further comprises a functional component;
wherein the foot comprises a conformal suction element that includes a semi-rigid seal plate; and
wherein the semi-rigid seal plate is conformal to a hat shaped stringer of an aircraft.

Abstract
A method and apparatus for a walking robot. A first end effector connected to a first end of a robotic arm is moved relative to a surface of a structure and away from a second end effector connected to a second end of the robotic arm. The first end effector is secured relative to the surface of the structure after moving the first end effector relative to the surface. The second end effector connected to the second end of the robotic arm is moved relative to the surface of the structure and toward the first end effector.

5. An apparatus comprising:
-
a walking robot having a first end and a second end, wherein the first end and the second end are movably connected by at least one joint for movement in a number of axes; a first end effector connected to the first end of the walking robot in which the first end effector comprises a first foot; and a second end effector connected to the second end of the walking robot comprising a second foot; wherein the second end effector includes a functional component that operates to perform an operation on a surface after the second foot is released from the second end and while the second foot remains attached to the surface; and wherein the walking robot is configured to communicate and coordinate with at least one other walking robot for performing a task on the surface. - View Dependent Claims (6, 7)

8. A method comprising:
-
moving a first end effector connected to a first end of a robotic arm relative to a surface of a structure and away from a second end effector connected to a second end of the robotic arm; and moving the second end effector connected to the second end of the robotic arm relative to the surface of the structure and toward the first end effector, wherein the first end effector comprises a first foot and the second end effector comprises a second foot; securing the first foot to a hat shaped stringer by a conformal suction element and the second foot to the surface of the structure, wherein the conformal suction element comprises a semi-rigid seal plate conformal to the hat shaped stringer; removing the second end from the second foot while the second foot remains attached to the surface; connecting a third end effector to the second end of the robotic arm, wherein the third end effector is a functional component; performing a manufacturing function on the surface with the third end effector; removing the third end effector from the second end of the robotic arm after performing the manufacturing function on the surface; and connecting the second end of the robotic arm to the second foot while the second foot is still attached to the surface and after removing the third end effector from the second end of the robotic arm. - View Dependent Claims (9)

10. A method comprising:
-
walking a robot across a surface of a structure using a first foot connected to a first end of the robot and a second foot connected to a second end of the robot; responsive to attaching the second foot to the surface of the structure, performing a function on the surface by a functional component that operates through a bottom of the second foot to perform an operation on the surface; and wherein the function is at least one of a manufacturing function, a maintenance function, or an inspection function, and wherein the function is performed on the surface using the functional component. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
