Patent number: 11911899Abstract: 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.Type: GrantFiled: February 13, 2023Date of Patent: February 27, 2024Assignee: Willow Garage, LLCInventors: Matei Ciocarlie, Scott Stanford

Patent number: 9831819Abstract: A rotating, pivoting mount for mounting a panel is disclosed. The mount can include a mounting block, a driveshaft, and a base. A socket in the mounting block can be mounted on a ball of the base to pivotally couple the panel to a structure. The ball can also include a cam profile, while the mounting block can include a complementary cam follower. As the mounting block rotates, therefore, the cam follower can follow a path set forth by the cam profile to tilt the mounting block about one axis as the mounting block rotates about a second axis. In this manner, the panel can be rotated and tilted—or moved about two axes—using a single motor. The use of a single motor can, in turn, reduce the cost and complexity of the system, while maintaining high efficiency for the panel (e.g., a solar panel) mounted thereon.Type: GrantFiled: March 24, 2016Date of Patent: November 28, 2017Assignee: KIRK-RUDY, INC.Inventors: Harry V.

Patent number: 9781885Abstract: An object lifting, pulling and digging apparatus has a pair of jaws that can be opened to enable positioning the jaws around a post, tree, and/or bush then closed around the post, tree, and/or bush. The jaws can then be raised to pull the post, tree, and/or bush from the ground. The jaws of the apparatus can also be closed and angled downwardly to drive the distal ends of the jaws into the ground, where the jaws can then be moved upwardly to dig the post, tree, and/or bush from the ground. The apparatus can easily be attached to a vehicle equipped with a universal quick attach hitch and having auxiliary hydraulics, for example, a “skid steer” type farm or construction vehicle.Type: GrantFiled: January 12, 2016Date of Patent: October 10, 2017Assignee: Danuser LLCInventor: Gary J. Niekamp

Patent number: 9744674Abstract: A gripper is described as including two lateral flanks that are directly or indirectly connected to each other at one end, providing a space between them including an actuator, the lateral boundaries of which space have at least one opening accessible from the outside. At least one louver runs across the opening and divides the opening such that the partial surfaces resulting from the louver limit or prevent accessibility to the opening. A method for manufacturing the gripper is also described.Type: GrantFiled: August 30, 2016Date of Patent: August 29, 2017Assignee: Röhm GmbHInventors: Eduard Schweigert, Jens Gräβle

Patent number: 9592888Abstract: A lifting device to retrieve a marine vehicle comprises a lifting arms portion pivotally connected with a vehicle capture portion. The lifting arms portion and the vehicle capture portion rotate independently of each other. The vehicle capture portion comprises a capture connector having a probe for insertion into a latch opening in the vehicle to thereby attach the vehicle to the lifting device. The lifting arras portion further comprises two lifting arms and two vehicle pads for engaging the vehicle when it is captured. As the vehicle rolls during recovery operations, springs disposed between the vehicle capture portion and lifting arms portion dampen rotational motion. Lift line connections are provided on distal ends of the vehicle capture portion, and the lifting arms.Type: GrantFiled: April 4, 2014Date of Patent: March 14, 2017Assignee: The United States of America as represented by the Secretary of the NavyInventors: Pedro Bracho, Bryan John

Patent number: 9585771Abstract: Finger parts flex and extend about joint sections. A wire is arranged along each finger part through the joint sections. A motor winds the wires to pull the wires in the flexing direction and cause the finger parts to flex. A polymer actuator arranged to correspond to a part of each wire is formed in an elongated shape of a polymer material and elastically deforms in response to an application of voltage and performs extension and contraction in the axial direction by being restored to the original shape in response to stoppage of the voltage application. A lock mechanism restricts relative movement between the wire and the motor after the wire has been wound up by the motor. The polymer actuator performs extension and contraction while relative movement is restricted by the lock mechanism, thereby pulling the wire in the flexing direction.Type: GrantFiled: October 11, 2013Date of Patent: March 7, 2017Assignee: TOYODA GOSEI CO., LTD.Inventors: Kazumasa Baba, Hiromitsu Takeuchi

Patent number: 9492928Abstract: A robotic gripping device allows for pinch and power grasps using interconnected phalanges with configurable connections. A distal phalange is rotatably connected to a proximal phalange. A contact phalange is rotatably connected to the proximal phalange. The contact phalange is rotatably connected to the distal phalange via a contact-distal pivot or rotation connection. In response to sufficient contact between the contact phalange and an object, the contact phalange is configured to rotate in a first direction toward the proximal phalange. The rotation of the contact phalange causes rotation of the distal phalange in a second direction toward the object. The contact-distal connection may be a configurable gear connection for adjusting the movement ratio of the contact and distal phalanges.Type: GrantFiled: November 5, 2014Date of Patent: November 15, 2016Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventor: Douglas A.
