Abstract: Method, system, medium, and implementation for robot-guided instrument insertion. A preplanned path between a three-dimensional (3D) entry pose on skin of a patient to a 3D pose of a target is generated for a surgery with a target inside the patient. The preplanned path is used by a robot as guidance to insert a surgical instrument from the 3D entry pose to reach the 3D pose of the target. During the surgery, a next pose is determined based on a current pose of the surgical instrument and the preplanned path as well as spatial relationship to surrounding anatomical structures and is used to move the surgical instrument thereto. An updated current pose of the instrument is then obtained via tracking when the robot is advancing the surgical instrument to the next pose. The process repeats until the instrument reaches the target pose.

Abstract: The present teaching relates to automated trocar/robot base location determination. An input related to a surgical operation includes a three-dimensional (3D) model for an organ with cut points on the organ forming a surgical trajectory. A surgical instrument is controlled by a robot to reach the cut points to carry out the operation. An insertion location for inserting the surgical instrument is identified.

Signals for configuring the surgical setting are then generated based on the insertion location for the surgical instrument and the base location for the robot.

Abstract: A restructurable hybrid-wing VTOL aircraft includes a fuselage, two wings, two canard wings and a cabin door. The two wings are provided to opposite sides of the fuselage. Each the wing is provided vertically and symmetrically by two rotary wing modules, and thus an H configuration to the fuselage can be formed. While the lower rotary wing module rotates to align the corresponding wing, a change of relative position with respect to the upper rotary wing module can be generated. Through the rotation of the lower rotary wing module, the vertical surface thereof would be transformed into a lift surface for enlarging the aspect ratio of the wing to improve the corresponding lift-drag ratio. Thereupon, a disadvantage of hyper flight-directional stability to the H-configured tail seat-type aircraft caused by the vertical area of the aircraft can be reduced, and so the tail-seat type aircraft can slide to emergency land.

Abstract: Method and system for estimating 3D camera pose based on 2D features. 3D virtual camera poses are generated, each of which is used to determine a perspective to project a 3D model of a target organ to create a 2D image of the target organ. 2D features are extracted from each 2D image and paired with the corresponding 3D virtual camera pose to represent a mapping. A 2D feature-camera pose mapping model is obtained based on the pairs. Input 2D features extracted from a real-time 2D image of the target organ are used to map, via the 2D feature-camera pose mapping model, to a 3D pose estimate of a laparoscopic camera, which is then refined to derive an estimated 3D camera pose of the laparoscopic camera via differential rendering of the 3D model with respect to the 3D pose estimate.
