METHOD OF MANUFACTURE WITHIN A CONFINED SPACE USING AN INNER END EFFECTOR AND AN OUTER END EFFECTOR

A method of manufacture within a confined space defined in part by a wall, comprises the following steps: moving an inner end effector (550) into the confined space, the inner end effector (550) having a clamping block (556) attached thereto; using first and second parallel telescoping lead screw assemblies (530, 540) to translate and rotate the inner end effector (550) until the inner end effector achieves a desired orientation with respect to a target within the confined space; positioning an outer end effector (640) over the target, the outer end effector (640) carrying an electromagnet; and energizing the electromagnet such that the outer end effector (640) magnetically attracts the clamping block (556) to clamp the wall between the inner and outer end effectors (550, 640).
