Abstract

A tool path generator utilizes a solid body model of a volume to generate a tool path for a manipulator to remove material of the volume with an energy applicator in a semi-autonomous mode. A material logger monitors movement of the energy applicator according to a cutting path taken by a practitioner in the manual mode, identifies material of the volume to which the energy applicator has been applied in the manual mode, and updates the solid body model based on the identified material. The tool path generator modifies the tool path based on the updated solid body model such that, for the semi-autonomous mode, the modified tool path accounts for the identified material of the volume to which the energy applicator has been applied in the manual mode.
