This is an adaptation of the open-source robot stereotaxic instrument originally described by Coffey et al., 2013.
By using stepper motors and 3D printed couplers, we can upgrade an existing stereotaxic instrument to a highly precise robot instrument for approximately $350.
This repository contains the coupler and assembly instructions to convert a Kopf Ultra Precise 962.
The robot is controlled by g-code sent to a CNC controller through Mach3.
