Patent ID: 8503759

Claim:
A system for registering a three-dimensional volume of a portion of a patient to a robotic arm, the system comprising: a. at least one robotic arm configured for manipulating a surgical instrument; b. a registration tool; c. a plurality of first touch point features configured to interface with the registration tool, each of the first touch point features having a fixed spatial relationship with the robotic arm; d. a plurality of markers; e. a plurality of second touch point features configured to interface with the registration tool, each of the second touch point features having a fixed spatial relationship with at least one of the plurality of markers; f. a first structure configured for releasable association with the patient, the first structure configured for association with the markers and to provide one or more of the second touch point features; and g. a computer system configured for computing a transformation for determining a position of the robotic arm relative to the three-dimensional volume of the patient based on positions of the first and second touch point features and the fixed spatial relationships of the touch point features with the robotic arm and the markers.
