1. A method of robotically controlling a reamer, the method comprising:
using processing circuitry, controlling movement of a robotic arm to position an end effector affixed to a distal end of the robotic arm at an acetabular surface of a patient, the end effector including a reamer extending distally therefrom;
receiving a first radiographic image of the reamer and the acetabular surface of the patient to determine a first maximum cutting depth in the acetabular surface; and
using the processing circuitry, electrically adjusting, based on the first radiographic image, a depth controller coupled to the reamer, to configure the depth controller to limit a maximum cutting depth of the reamer to the first maximum cutting depth.
