1. A surgical system for positioning a prosthetic component on an anatomy of a patient, comprising:

  • a surgical tool configured to engage the prosthetic component;

    a force system configured to provide at least some force to the surgical tool; and

    a controller programmed to;

    compare a target pose of the prosthetic component and an actual pose of the prosthetic component engaged by the surgical tool; and

    generate control signals that cause the force system to allow movement of the surgical tool within a range of movement and provide haptic feedback to constrain a user'"'"'s ability to manually move the surgical tool beyond the range of movement, wherein the haptic feedback resists movement of the surgical tool by the user that would cause substantial deviation between at least one aspect of the actual pose of the prosthetic component and a corresponding aspect of the target pose of the prosthetic component;

    wherein the controller is programmed to generate control signals that cause the force system to maintain the haptic feedback as the user implants the prosthetic component on the anatomy.
