1. An instrument drive system configured to manage a relative feed position of an instrument in an instrument channel of an endoscope assembly and manage a relative feed position of said instrument, wherein said instrument drive system comprises:
two drive wheels, a working channel, a device application, and a controller;
said controller comprises a device memory containing said device application;
said two drive wheels are arranged around said working channel within said instrument drive system;
said instrument drive system is configured to work in conjunction with said instrument comprising a plurality of machine-readable signatures;
said instrument drive system further comprises an optical data reader configured to read a portion of said plurality of machine-readable signatures as said instrument is feed into and removed from said instrument drive system;
said device application is configured to decode said plurality of machine-readable signatures and thereby determine a relative feed position of said instrument within said instrument drive system and said endoscope assembly;
said two drive wheels are in communication with said device application;
said device application is configured to feed said instrument into and out of said instrument drive system and said endoscope assembly according to inputs from said device application and a plurality of user inputs of said instrument drive system;
said instrument is configured to be inserted into said instrument drive system and through said working channel; and
said two drive wheels comprise an adjustable tensioner to allow for fine tuning of instrumentation feed speed, and a clutch-brake assembly which can allow for decoupling of a motor drive and a brake.
