Modern experiments for the search of extremely rare processes require high momentum resolutions (order of 50-100 keV/c) tracking systems for particle momenta in the range of 50-100 MeV/c, dominated by multiple scattering contributions. A typical tracking detector with high precision and ability to withstand high rates is a full stereo, high granularity Drift Chamber. Due their high wire density, the use of the classical feed-through technique as wire anchoring system can hardly be implemented and therefore it is necessary to develop new wiring strategies. To this purpose, a wiring robot has been designed and build: for monitoring the solder quality of the wire to the supporting Printed Circuit Boards; for applying mechanical a pre-defined tension to the wires and maintaining it constant and uniform through the whole chamber; for monitoring the wire positions and their alignments within a few tens of $\mu$m; for anchoring the wires to their support with a contactless soldering system. The wiring robot consists of: - List item **WIRING SYSTEM**: a semiautomatic wiring machine with a high precision on wire mechanical tensioning ($<$0.05 g) and on wire positioning ($<$20 $\mu$m) for a simultaneous wiring of multi-wire frames; - List item **SOLDERING SYSTEM**: a contact-less infrared laser soldering tool for anchoring the wires to the supporting PCB; - List item **EXTRACTION SYSTEM**: an automatic handling system for removing the multi-wire frames from the wiring system and for storing them and whit adjustable wire tension. All subsystems of the wiring robot are managed and synchronized with a real-time system, based on a National Instrument CompactRIO platform. The wiring robot has been used for the wiring phase of MEG II Drift Chamber.
