  • Patent number: 11911903
    Abstract: Various embodiments of the present technology generally relate to robotic devices and artificial intelligence. More specifically, some embodiments relate to a robotic device for picking items from a bin and perturbing items in a bin. The robotic device may include one or more picking elements and one or more perturbation elements for disturbing a present arrangement of items in the bin. In an exemplary embodiment, a perturbation element comprises a compressed air valve. In some implementations, the robotic device may also include one or more computer-vision systems. Based on image data from the one or more computer-vision systems, a strategy for picking up items from the bin is determined. When no strategies with high probability of success exist, the robotic device may perturb the contents of the bin to create new available pick-up points.

Each end effector has a pair of oppositely-positioned locator pins, at least one of which is selectively moveable toward the other. A controller is used to control the positioning of the frame via the robots and end effector by executing method instructions to cause the robots to align the locator pins of the end effectors with the openings of the frame, and to insert the aligned locator pins into the openings toward the center axis from outside of the vehicle frame. The robots lift the frame from a first conveyor, with weight of the vehicle frame born by the locator pins during the lift. The robots also rotate the frame about the center axis and lower the vehicle frame onto a second conveyor.

  • Patent number: 8979152
    Abstract: 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.

Each gripping finger socket (9, 10) is provided with an electric or pneumatic coupling for various gripping fingers (17, 27, 37) that can be connected. A rotating drive (13) is present between the gripping finger sockets (9, 10) on which a tool can be placed for releasing or attaching a fastening apparatus, such as a bolt. With this relatively simple construction, weights of several hundred kilos can be lifted and positioned accurately, for example in a processing machine.

    Abstract: A displacement measuring cell may be used to measure linear and/or angular displacement. The displacement measuring cell may include movable and stationary electrodes in a conductive fluid. Electrical property measurements may be used to determine how far the movable electrode has moved relative to the stationary electrode. The displacement measuring cell may include pistons and/or flexible walls. The displacement measuring cell may be used in a touch-sensitive robotic gripper. The touch-sensitive robotic gripper may include a plurality of displacement measuring cells mechanically in series and/or parallel. The touch-sensitive robotic gripper may be include a processor and/or memory configured to identify objects based on displacement measurements and/or other measurements. The processor may determine how to manipulate the object based on its identity.

  • Publication number: 20150019003
    Abstract: A robot system according to an aspect of an embodiment includes a robot, a determination unit (work determination unit), a selection unit (chucking direction selection unit), and an instruction unit. The robot has a robot hand (hand) including three or more chuck jaws. The determination unit obtains information on a member formed including a substantially ring shape, and determines a state of the member. The selection unit selects whether to hold the member with the chuck jaws from an inner peripheral side or outer peripheral side based on the determination result of the determination unit. The instruction unit instructs the robot to perform operations of transporting the member while holding the member with the chuck jaws based on the selection result of the selection unit, and assembling a predetermined processed product using the member.

  • Patent number: 8920721
    Abstract: A machine for treatment and/or analysis of biological samples is provided. The machine includes a hinged arm to which a clamp for gripping a first biological sample holder is fixed. The clamp includes first and second arms able to move relative to each other along a gripping position between a first position of gripping the first biological sample holder, and a first position of releasing the biological sample holder. Each arm of the clamp includes a groove. When the first and second arms are in the first position of release, the first and second grooves are spaced away from each other along the gripping direction, and when the first and second arms are in the first gripping position, the first and second grooves are brought closer to each other along the gripping direction, so as to be able to receive lateral edges of and grip the first biological sample holder.

  • Patent number: 8919714
    Abstract: A compliant tool holder is provided for use with robots, unmanned ground vehicles, and the like. The compliant tool holder is characterized in that it involves the use of means for compliance, such as springs, rubber, plastics, metals, composites, shock mounts, vibration mounts, or similar means for permitting compliant movement in three rotational and three translational degrees of freedom during end effector changes. The compliant tool holder reduces costs associated with automated tool change in the field, and allows for more rapid switching of end effectors, enabling a greater range of uses for robots and unmanned ground vehicles.

  • Patent number: 8915527
    Abstract: Before chuck 20 is opened, coil spring 22 is compressed, and coil spring 22 applies downward force to holding nails 24. Accordingly, when the chuck 20 is opened, resultant force that opens the chuck 20 and the restoring force of the coil spring 22 causes the holding nails 24 to automatically move in oblique downward directions. As a result, the holding nails 24 move to positions that are laterally close to the holding target workpiece 26a. At this time, when other workpieces 26b and 26c neighbor the holding target workpiece 26a, the holding nails 24 can move the neighboring workpieces 26b and 26c from the workpiece 26a so as to flick away the neighboring workpieces 26b and 26c.

  • Patent number: 8909376
    Abstract: Disclosed herein is a method of controlling a robot hand similar to a hand of a human being such that the robot hand naturally and safely grasps an object. The robot hand, including fingers and a palm, is capable of naturally and safely grasping an object, by the tip of each finger performing impedance control while following the optimal path on a Cartesian coordinate system, although the robot hand cannot reach a position ideal to grasp the object due to sensor errors or shape information of the object to be grasped is not correctly recognized. Also, the robot hand is capable of stably grasping the object even when moving or manipulating the object.
