Claim 0:
1. A surgical system, comprising:
a robot arm configured to position a tool for receiving one or more drilling instruments relative to patient anatomy; and
a controller coupled to the robot arm and configured to:
receive a target trajectory for drilling a hard tissue, the target trajectory having a target entry point, a target diameter, a target axis, and a target depth;
analyze a three-dimensional model of the hard tissue, including a surface curvature of the hard tissue at the target entry point;
determine that a skiving threshold is surpassed, wherein surpassing the skiving threshold indicates skiving is at least likely while drilling along a target orientation; and
determine an anti-skiving trajectory for drilling the hard tissue before drilling the target trajectory, wherein the anti-skiving trajectory differs from the target trajectory by at least one of entry point, diameter, axis, or depth.
