The gripping mechanism is a gripping mechanism for gripping a cuvette T, the gripping mechanism comprising: a sandwiching section 50 for holding the cuvette T in a laterally sandwiching manner; a pressing section 60 for pressing downward an upper end surface of the cuvette T held in a sandwiching manner by the sandwiching section 50, wherein the pressing section 60 is arranged such that, with the cuvette T being held in a sandwiching manner by the sandwiching section 50, a central axis of the cuvette T along a vertical direction coincides mutually with a central axis of the pressing section 60 in the vertical direction.

A mechanical device that has the ability to manage and set explosives cones in the rocks that form the hanging, which can be operated remotely, avoiding the danger of the current state of the art where operators place explosive using bamboo sticks, before detonating them, causing an imbalance in the hanging. The mechanical device also known as cone-holder, is located at the end of an automated and semi autotransportable manipulator arm for releasing hangings.

Provided is a robot hand applicable to purpose for holding various types of objects different in size or shape. The robot hand includes a hand base, a first hand arm having a first butting part and a first adsorption part, a second hand arm having a second butting part and a second adsorption part, and a driving mechanism for moving the first and second butting parts in directions to approach each other or separate from each other by moving the first and second hand arms relatively to each other.

A hand control apparatus including an extracting unit extracting a grip pattern of an object having a shape closest to that of the object acquired by a shape acquiring unit from a storage unit storing and associating shapes of plural types of objects and grip patterns, a position and posture calculating unit calculating a gripping position and posture of the hand in accordance with the extracted grip pattern, a hand driving unit causing the hand to grip the object based on the calculated gripping position and posture, a determining unit determining if a gripped state of the object is appropriate based on information acquired by at least one of the shape acquiring unit, a force sensor and a tactile sensor, and a gripped state correcting unit correcting at least one of the gripping position and the posture when it is determined that the gripped state of the object is inappropriate.

A three-finger mechanical gripper system is provided, which includes a torque sensor, a three-finger mechanical gripper, an image capturing module and a controller. The three-finger mechanical gripper is connected to the torque sensor. The controller is connected to the torque sensor, the three-finger mechanical gripper and the image capturing module. The image capturing module captures the image of a training object. The controller controls the three-finger mechanical gripper to grip the training object by a plurality of gripper postures respectively and calculates the torque information of each gripper posture according to the measured values of the torque sensor. Then, the controller performs a training process according to the image of the training object and the torque information of the gripper postures in order to obtain a training result of the training object.

There is provided a robot hand that grips and positions a work with a certain gripping force, and that rapidly conveys the work to execute assembling after gripping the work.

A robot hand is provided and includes a robot hand control unit that has at least three gripping fingers on a base and controls the robot hand, a plurality of drive mechanisms that brings the three gripping fingers independently close to or separate from each other, a plurality of drive control units that individually controls each of a plurality of drive sources of the plurality of drive mechanisms, and a distribution control unit that is disposed on the base and distributes an instruction value from the robot hand control unit to the plurality of drive control units associated with the plurality of gripping fingers. At least one of the gripping fingers includes an integrally formed drive source and drive control unit.

A robotic end-effector to provide conformal object interaction. The end-effector has at least one finger with an inner portion or engaging side and one or more degrees of freedom. A jamming conformal pad is on the inner portion of the at least one finger. The jamming conformal pad has a compliant configuration in which the jamming conformal pad is compliant and configured to distribute across a surface of an object and, if contoured, infiltrate into any variations (e.g., indentations) in the surface, defining a conformal engaging surface configured to match and mate with the surface. The jamming conformal pad has a stiff configuration in which the jamming conformal pad is stiff or relatively stiff as compared to the jamming conformal pad in the compliant configuration, and which substantially maintains a shape of the conformal engaging surface.

An article gripping device causes a gripping member to grip an article, and subsequently discharge the article by releasing the gripping of the article by the gripping member. The article gripping device is provided with a gripping member driving mechanism to drive the gripping member, and a controller to control the gripping member driving mechanism. The controller has, as control modes for the gripping member driving mechanism, a first control mode and a second control mode that is separate from the first control mode. In the first control mode, the controller controls the gripping member driving mechanism to cause the gripping member to execute a first operation of gripping the article and subsequently releasing the gripping of the article. In the second control mode, the controller controls the gripping member driving mechanism to cause the gripping member to execute a second operation of removing matter adhering to the gripping member.
