1. A surgical system, comprising:
a surgical robot comprising an instrument holder, the instrument holder configured to couple with an instrument having a working end, wherein the instrument is translatable within the instrument holder when coupled to the instrument holder;
a position sensor for measuring a displacement of the instrument with respect to the instrument holder as the instrument is translated relative to the instrument holder; and
a computer comprising a processor configured to:
determine a location of the working end with respect to a pre-determined location on a bone based on a pre-determined distance of the instrument holder relative to the pre-determined location and the measured displacement of the instrument relative to the instrument holder.
