Patent number: 11103315Abstract: Systems and methods are described in which a tracker is attached to an object and a localizer cooperates with the tracker to generate localizer data associated with the object. A vision device generates image data associated with the object and an environment surrounding the object within a field-of-view of the vision device. A navigation computer associates a virtual object with the object; determines a position and orientation of the virtual object in a coordinate system of the localizer based on the localizer data; combines the localizer data and the image data into a common coordinate system; merges the localizer data and the image data to identify data points in the image data having coordinates located outside of the virtual object; and associates a second virtual object with the identified data points, wherein the second virtual object defines a region that is to be avoided.Type: GrantFiled: May 21, 2020Date of Patent: August 31, 2021Assignee: Stryker CorporationInventor: Donald W.

Publication number: 20210260769Abstract: A robotic device includes one or more actuators to position an end effector in a plurality of degrees of freedom. A navigation system tracks an actual position of the end effector. A controller identifies a condition wherein the actual position of the end effector contacts a virtual constraint. The controller determines that an anticipated movement of the end effector from an actual position to the home position would cause a collision between the end effector and a virtual constraint and computes a target position of the end effector that avoids the collision. The target position is spaced from the actual position and computed with respect to the virtual constraint. The one or more actuators are controlled to move the end effector from the actual position to target position along the virtual constraint.Type: ApplicationFiled: May 11, 2021Publication date: August 26, 2021Applicant: Stryker CorporationInventors: David Gene Bowling, Timothy J.
