Kinetic and dimensional optimization for a tendon-driven gripper
10987801 · 2021-04-27 · ·

A tendon-driven robotic gripper is disclosed for performing fingertip and enveloping grasps. One embodiment comprises two fingers, each with two links, and is actuated using a single active tendon. During unobstructed closing, the distal links remain parallel, creating exact fingertip grasps. Conversely, if the proximal links are stopped by contact with an object, the distal links start flexing, creating a stable enveloping grasp. The route of the active tendon and the parameters of the springs providing passive extension forces are optimized in order to achieve this behavior. An additional passive tendon is disclosed that may be used as a constraint preventing the gripper from entering undesirable parts of the joint workspace. A method for optimizing the dimensions of the links in order to achieve enveloping grasps of a large range of objects is disclosed and applied to a set of common household objects.

SURGICAL SYSTEM WITH VARIABLE ENTRY GUIDE CONFIGURATIONS

A surgical system uses a single entry port in a wide variety of surgeries. To insert multiple surgical instruments into a patient through a single entry port requires that the shaft of at least one of the surgical instruments be bent between the base of the surgical instrument and the point where the shaft contacts a channel in an entry guide. Each surgical instrument is positioned by an instrument manipulator positioning system so that when the shaft is inserted in a channel of the entry guide, any bending of the shaft does not damage the surgical instrument and does not inhibit proper operation of the surgical instrument.

Surgical system with variable entry guide configurations

A surgical system uses a single entry port in a wide variety of surgeries. To insert multiple surgical instruments into a patient through a single entry port requires that the shaft (262A1) of at least one (260A1) of the surgical instruments be bent between the base of the surgical instrument (260A1) and the point where the shaft contacts a channel in an entry guide (270A). Each surgical instrument (260A1, 260A2) is positioned by an instrument manipulator positioning system (231A) so that when the shaft is inserted in a channel of the entry guide (270A), any bending of the shaft does not damage the surgical instrument and does not inhibit proper operation of the surgical instrument.

DEEP MACHINE LEARNING METHODS AND APPARATUS FOR ROBOTIC GRASPING

Deep machine learning methods and apparatus related to manipulation of an object by an end effector of a robot. Some implementations relate to training a semantic grasping model to predict a measure that indicates whether motion data for an end effector of a robot will result in a successful grasp of an object; and to predict an additional measure that indicates whether the object has desired semantic feature(s). Some implementations are directed to utilization of the trained semantic grasping model to servo a grasping end effector of a robot to achieve a successful grasp of an object having desired semantic feature(s).
