Publication number: 20250121856Abstract: The present disclosure provides autonomous vehicle systems and methods that include or otherwise leverage a machine-learned yield model. In particular, the machine-learned yield model can be trained or otherwise configured to receive and process feature data descriptive of objects perceived by the autonomous vehicle and/or the surrounding environment and, in response to receipt of the feature data, provide yield decisions for the autonomous vehicle relative to the objects. For example, a yield decision for a first object can describe a yield behavior for the autonomous vehicle relative to the first object (e.g., yield to the first object or do not yield to the first object). Example objects include traffic signals, additional vehicles, or other objects. The motion of the autonomous vehicle can be controlled in accordance with the yield decisions provided by the machine-learned yield model.Type: ApplicationFiled: December 20, 2024Publication date: April 17, 2025Inventors: Colin Jeffrey Green, Wei Liu, David McAllister Bradley, Vijay Subramanian

Publication number: 20240268904Abstract: Surgical systems and methods involve manipulation of a bone. A robotic manipulator supports and moves a surgical tool that has a cutting bur rotatable about a cutting axis. Controller(s) control the manipulator to align the cutting axis to a target axis associated with the bone and advance the cutting bur along the target axis towards a cortical region of the bone. The controller(s) control the surgical tool to rotate the cutting bur about the cutting axis and contact the cortical region. The controller(s) detect, from sensor(s), forces applied to the cutting bur by the cortical region and compare the sensed forces to a threshold indicative of skiving of the cutting bur relative the cortical region. In response to the sensed forces exceeding the threshold, the controller(s) adjust control of the manipulator and/or surgical tool to reduce forces applied to the cutting bur by the cortical region.Type: ApplicationFiled: March 26, 2024Publication date: August 15, 2024Applicant: MAKO Surgical Corp.Inventors: Jamil Elbanna, Michael Prieto, Vijay Subramanian, Jienan Ding

Robotic surgical system and methods utilizing virtual boundaries with variable constraint parameters
Patent number: 11986260Abstract: Surgical systems and methods for utilizing virtual boundaries having different constraint parameters. A robotic manipulator supports and moves a surgical tool for treating a bone structure. A navigation system tracks the surgical tool and the bone structure. Controller(s) obtain a virtual model of the bone structure and define first and second virtual boundaries relative to the virtual model. The first virtual boundary has a first constraint parameter and the second virtual boundary has a second constraint parameter that is different than the first constraint parameter. The virtual model and virtual boundaries are registered to the bone structure. The manipulator moves the surgical tool relative to the bone structure and the first and second virtual boundaries. The surgical tool is constrained relative to the first virtual boundary in accordance with the first constraint parameter and constrained relative to the second virtual boundary in accordance with the second constraint parameter.Type: GrantFiled: April 20, 2022Date of Patent: May 21, 2024Assignee: MAKO Surgical Corp.Inventors: Jamil Elbanna, Michael Prieto, Vijay Subramanian -

Patent number: 11827240Abstract: Systems and methods for autonomous vehicle motion planning are provided. Sensor data describing an environment of an autonomous vehicle and an initial travel path for the autonomous vehicle through the environment can be obtained. A number of trajectories for the autonomous vehicle are generated based on the sensor data and the initial travel path. The trajectories can be evaluated by generating a number of costs for each trajectory. The costs can include a safety cost and a total cost. Each cost is generated by a cost function created in accordance with a number of relational propositions defining desired relationships between the number of costs. A subset of trajectories can be determined from the trajectories based on the safety cost and an optimal trajectory can be determined from the subset of trajectories based on the total cost. The autonomous vehicle can control its motion in accordance with the optimal trajectory.Type: GrantFiled: December 22, 2020Date of Patent: November 28, 2023Assignee: UATC, LLCInventors: Vijay Subramanian, Moslem Kazemi, David Mcallister Bradley, Michael Lee Phillips

Patent number: 11337766Abstract: Disclosed herein are techniques for preparation of a bone structure wherein a robotically controlled cutting bur is utilized for both milling the entry point at the outer cortical region and cannulation of the cancellous bone region for receipt of an implant. A robotic manipulator supports and moves the cutting bur and one or more controllers analyze measurements from sensors and, in response, control the robotic manipulator and/or the cutting bur for purposes such as landmark detection to determine entry point, avoiding tool skiving at entry point, and avoidance of cortical wall breach during cannulation. Also described are techniques for managing feed rate, rotational cutting speed, or mode of operation depending on operational conditions surrounding various stages of cannulation. A control interface is also provided to enable the user to manage or adjust cutting bur operation and feed rate.Type: GrantFiled: March 12, 2020Date of Patent: May 24, 2022Assignee: MAKO Surgical Corp.Inventors: Jamil Elbanna, Jienan Ding, Michael Prieto, Vijay Subramanian
