An electronic device can include a motor that rotates a shaft that is coupled to a gear. A belt or a chain can be placed in contract with the gear and other rotational devices. For optimum performance, the chain or chain should be adjusted to an optimum tension. The tension can be adjusted by moving the motor and securing the motor in a position the provided the optimum tension. Alternatively, the motor can be in a fixed rigid position and an idler pulley in contact with the belt or chain can be positioned to provide the optimum tension.

A robot hand apparatus includes a base, three finger mechanisms, a thumb mechanism, and three motors for the three finger mechanisms. The base corresponds to a part of the hand of a human, i.e. a palm and dorsum of a human. Each of three finger mechanisms is elongated in almost the same direction from the end of the base and is adapted to be actuated by the motor. The thumb mechanism is elongated from the different portion from the base. The thumb mechanism and the finger mechanism close to the thumb mechanism are configured to define a U-shape space.

A machine tool is provided which can execute various works while suppressing increase in cost or size. The machine tool includes a tool spindle device which is a movable member which can move with respect to a mounting surface of the machine tool, and one or more serial-manipulator-type robots attached on the tool spindle device, which can move with the tool spindle device, and which have two or more degrees of freedom, and the robot includes two or more end effectors provided at positions different from each other with one or more joints therebetween.

Disclosed is a gripper for robot hand capable of adaptive grasp, including a finger unit having one or more finger which includes a first link of which one end is rotatably fixed to a casing; a second link of which one end is jointly coupled with the other end of the first link; a third link of which one end is rotatably fixed to the casing, which is operated by receiving a driving force from the outside; a fourth link of which one end is jointly coupled with the other end of the third link; and a gripping member jointly coupled with the other end of the second link and the other end of the fourth link.

Exemplary embodiments relate to improvements in robotic systems to reduce biological or chemical harborage points on the systems. For example, in exemplary embodiments, robotic actuators, hubs, or entire robotic systems may be configured to allow crevices along joints or near fasteners to be reduced or eliminated, hard corners to be replaced with rounded edges, certain components or harborage points to be eliminated, shapes to be reconfigured to be smoother or flat, and/or or surfaces to be reconfigurable for simpler cleaning.

A hand at a robot arm leading end is provided with a mounting portion for a finger. The mounting portion includes a guiding unit that guides a supported portion of the finger so as to enable the supported portion to pass through from one end part of the guiding unit 31 to another end part thereof. The mounting portion further includes a lock mechanism. The lock mechanism moves the supported portion from any of end parts of the guiding unit 31 toward a mount position between the end parts, to thereby bring the supported portion of the finger into a restricting state at the mount position. Moreover, the lock mechanism moves the supported portion toward any of the end parts from the restricting state, to thereby bring the supported portion from the restricting state into a releasing state.

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 gripping device for handling sample containers is presented. The gripping device comprises a number of rigid fingers having non-gripping surfaces adapted to reduce adhesion between the non-gripping surfaces and labels. The number of rigid fingers collectively grip a sample container. Each finger comprises a gripping surface to contact the sample container while the sample container is gripped by the gripping device. The non-gripping surface of each finger is different from the gripping surface. The non-gripping surface of at least one of the fingers is at least partially corrugated. A sample container processing system comprising such a gripping device is also presented.
