Abstract: A valve robot hand includes a driving device, a transmitting sleeve, a first return spring, a first centering sleeve configured to sleeve on a screw cap of a valve handle, and a driving fork configured to couple with the valve handle. A lower end of the transmitting sleeve is connected with the driving fork. The driving fork is provided with a first through-hole configured to sleeve on the screw cap of the valve handle. The first through-hole is coaxial with the transmitting sleeve. The driving fork is sleeved on the first centering sleeve through the first through-hole such that the first centering sleeve is capable of moving in the transmitting sleeve along its axial direction. The first return spring is configured to exert a downward elastic force on the first centering sleeve.
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.
Abstract: A device for excavating a precise plug of sand from a sand surface and umbrella assemblies are shown and described.

Abstract: A device for detecting a position of a hoisting frame includes one or more image sensors connected movably to the hoisting frame and protruding outside a periphery thereof in a position of use. The image sensors can be movable between the position of use and a protected position lying within the periphery of the hoisting frame. The device can be provided with means for biasing the image sensor(s) from the protected position to the position of use. A method for controlling a hoisting frame suspended from a crane includes moving the hoisting frame to a first position under the control of an automatic control system, holding the hoisting frame stationary in the first position, making one or more image recordings of the area around the hoisting frame in the first position and moving the hoisting frame to a second position on the basis of the image recording(s), wherein the image recording(s) is/are made by one or more image sensors connected to the hoisting frame.
Abstract: A manhole adjustment ring removal assembly includes a frame. A pair of legs is pivotally coupled to the frame. Each of the legs has an upper end and a lower end and each end has one of a pair of the plates attached thereto. The plates each have an outer edge extending outwardly away from a corresponding one of the legs. The outer edges taper to point and are extendable between an adjustment ring and a cone base. A drive assembly is mounted on the frame and is mechanically coupled to the legs. The drive assembly is actuated in a first direction moving the lower ends away from each other and in a second direction moving the lower ends toward each other. A lift ring is attached to the frame to be engaged with a cable to lift the frame when the plates are positioned under the adjustment ring.
Abstract: A device for removing polycrystalline silicon rod pairs from a Siemens reactor has a body dimensioned to fit over a single rod pair. Once the rod pair is within the body, the body and enclosed rod pair is removed.

Abstract: A retriever for retrieving objects, including an elongated arm; a container on one end of the arm having an opening providing access to an interior of the container; and an actuator on the other end of the arm. Operation of the actuator causes movement of a scraper plate between an open position and a closed position. When in the open position, the scraper plate is spaced from the opening. When in the closed position, the scraper plate contacts the container at the opening. If an object is located in the space between the scraper plate and the opening, then movement of the scraper plate between the open and closed positions pushes the object into the interior of the container. The object can then slide through a channel along the arm, and be retrieved by a user from an opening in the channel near the trigger.
Abstract: A food serving apparatus with a bottom having two lateral sides, a front side, and a back side, and a center axis, and two flexible side walls, each of which are capable of automatically bending toward a center axis of the food serving apparatus in response to insertion of the apparatus into an open end of a flexible bag.
Abstract: An automatic locking mechanism can include one or more annular elements having teeth facing each other or facing away from each other. The automatic locking mechanism can include a rod disposed between the annular elements. The rod can have one or more pins configured to interface with the teeth of the annular elements. The pins and the teeth are also configured to rotate the rod when the annular elements move relative to the rod. The rotation of the rod can toggle a hook end of the rod in a hook receptacle, which can change states of the locking mechanism.
