1. A coordinate-based robotically assisted surgical method comprising:
fixing a first tracking mechanism relative to an anatomical location of a bone;
registering, using a surgical tracking system, a virtual coordinate system relative to the first tracking mechanism;
fixing a second tracking mechanism of a robotic surgical device relative to the anatomical location of the bone;
transferring the virtual coordinate system from the surgical tracking system to the robotic surgical device;
removing the first tracking mechanism from the bone; and
causing the robotic surgical device to execute a portion of a surgical procedure based on the virtual coordinate system.
