      abstract     = {The investigation of edge plasmas at the stellarator W7-X
                      requires a flexible tool for integration of a variety of
                      different diagnostics as e.g. electrical probes, probing
                      magnetic coils, material collection, or material exposition
                      probes, and gas injection. A multi-purpose manipulator (MPM)
                      system has been developed and attached to the W7-X vessel
                      before the operational phase 1.1. The system was designed as
                      user facility for many diagnostics, which can be mounted on
                      a unique interface without breaking the W7-X vacuum. The
                      manipulator system, located in the equatorial plane,
                      transports the inserted diagnostic probe to the edge of the
                      inner vacuum vessel. From there, the probe can be moved over
                      a maximum distance of 350 mm to different positions inside
                      the plasma with a maximum acceleration and deceleration of
                      30 m/s2. Acceleration, speed, and stroke depth are
                      individually adjustable and programmable by a PLC system
                      within predetermined limits. The MPM system can be equipped
                      with multifunctional probes and is prepared for
                      cooling/heating of the probe head, gas injection, and a
                      flexible setting of the electrical diagnostic. In the paper,
                      the MPM components, their functionalities, and the interface
                      to the probe head are described. The scope of physical
                      parameters is presented for the development of diagnostic
                      probes applicable in the MPM user facility. This also
                      includes the operational parameters for the movements and
                      the electrical environment for measurements. The operation
                      of the MPM during the OP1.1 is demonstrated on the
                      application of a multipurpose probe head, including
                      electric, magnetic, and thermal probes.},
