TORU (Tele-robotically Operated Rendezvous Unit,[1] Russian: Телеоператорный Режим Управления, lit.
The TORU system became known to the public in 1997 when it was used during the manual approach of Progress M-34 to Mir that ended with a dangerous collision that punctured the Spektr module causing a slow leak that left it permanently uninhabitable.
It was an approach of a previously used Progress spacecraft with the purpose of research work on further improvement of TORU.
TORU has a similar layout to the controls of a Soyuz spacecraft with two joysticks which can be used to manually fly the ship.
TORU also transfers sounds from the spacecraft that may provide indirect information about the docking process.
