A holding device capable of reliably holding a workpiece with a simple operation. The holding device is for holding a workpiece and includes a base part; a guide member mounted on the base part and extending in a first direction; and a first holding mechanism movable in the first direction by an external force being applied thereto, the first holding mechanism being capable of holding the workpiece. Further, there is a second holding mechanism including a first member and a second member which face each other across the first holding mechanism in the first direction and each of which is movable relative to the base part by being driven by an actuator. The second holding mechanism is capable of sandwiching and holding the workpiece between the first member and the second member by changing a distance between the first member and the second member in the first direction.

Clamping or gripping device with a main body, with guide portions provided on the main body, with jaws which are movable along the guide portions in a direction of movement, which can be moved between an inner stroke position and an outer end-of-stroke position, the jaws each having a row-of-teeth portion with, in each case, a length extending in the direction of movement, and with multiple pinions, the axes of rotation of which lie in a plane lying parallel to the respective row-of-teeth portions, the pinions interacting with the respective row-of-teeth portion to drive the jaws.

A gripper for a transport system of a picking device having horizontal storage surfaces for storing and dispensing small piece goods of different shapes and/or surface properties is provided. The gripper comprises a drop table extending in first and a second horizontal directions and having a storage and dispensing end face. Two elongated gripping jaws are arranged above the drop table extending in the first horizontal direction, and are fastened to a gripping jaw guide arrangement. At least one of the gripping jaws is movable in the second horizontal direction and at least one of the gripping jaws has a gripper coupler in its end portion facing away from the gripping jaw guide arrangement, and at least one transport attachment with an attachment coupler. The gripper and attachment couplers interact so that a transport attachment is releasably fixed at an end portion of a gripping jaw.

A remote controlled luggage handler apparatus for loading and unloading luggage from tour buses includes a carrier body having a pair of drive tracks. A multi-axis arm has a base pivot unit coupled to a body top side, a proximal segment coupled to the base pivot unit, a distal segment, and a head pivot unit. A jaw comprises a jaw support coupled to the head pivot unit, a fixed mandible coupled to the jaw support, and a sliding mandible slidably coupled to the jaw support to secure a suitcase between the fixed mandible and the sliding mandible. A CPU, a first transceiver, and a battery are coupled within the carrier body. A remote control is in operational communication with the first transceiver to control the drive tracks and the arm. A charging port is configured to be installed within a storage bay of a tour bus to charge the battery.

A method for driving a hand includes: detecting a relative position of a first finger part and a second finger part as of when the first finger part and the second finger part pinch a target object therebetween, as a reference relative position, by a position detection unit; moving the relative position of the first finger part and the second finger part to a target relative position where the first finger part and the second finger part are spaced further apart from each other than at the reference relative position by an amplitude of vibration or more, by a drive unit, on accepting an instruction to release the target object pinched by the first finger part and the second finger part; and causing at least one of the first finger part and the second finger part to vibrate by the drive unit, when the target relative position is achieved.

A loading robot hand includes a first member, a second member, and a drive unit. The second member can hold an article between the first member and the second member. The drive unit moves the second member in a direction toward and away from the first member. The drive unit includes a moving base, a fluid cylinder, a pressure regulator, and a controller. The moving base is slidably movable by driving a drive source. The fluid cylinder is attached to the moving base. The pressure regulator can change operating pressure of the fluid cylinder. The controller controls the pressure regulator. A direction of expansion and contraction of the fluid cylinder is parallel to a direction of slide movement of the moving base. The second member is attached to a portion of the fluid cylinder that is movable relative to the moving base.

A grip apparatus is provided. The grip apparatus includes a first finger; a second finger configured to face the first finger, a first link configured to have a first end connected to the first finger, a second link configured to have a first end connected to the second finger, and a differential apparatus including a motor and configured to connect a second end of the first link and a second end of the second link. The differential apparatus rotates the first link and the second link in different directions when the motor is driven. The differential apparatus rotates the first link in a first direction when the second link rotates in the first direction by an external force.

Clamping or gripping device with a main body, with guide portions provided on the main body, with jaws which are movable along the guide portions in a direction of movement, which can be moved between an inner stroke position and an outer end-of-stroke position, the jaws each having a row-of-teeth portion with, in each case, a length extending in the direction of movement, and with multiple pinions, the axes of rotation of which lie in a plane lying parallel to the respective row-of-teeth portions, the pinions interacting with the respective row-of-teeth portion to drive the jaws.

A robotic surgical tool includes a drive housing having first and second ends, a carriage movably mounted to the drive housing, and a shaft extending from the carriage and penetrating the first end, the shaft having an end effector arranged at a distal end. An activating mechanism is secured to the carriage and includes a transmission link pivotably coupled to the carriage, a transmission drive gear rotatably mounted to a transmission link, a drive gear rotatably mounted to the carriage and operatively coupled to the transmission drive gear, and a transmission driven gear rotatably mounted to the transmission link and driven by rotation of the transmission drive gear. The transmission link is pivotable between a first and second positions to actuate the activating mechanism to perform first and second functions, respectively, of the end effector.

The purpose of the present invention is to provide a gripping mechanism capable of stably gripping transportation articles of various sizes.

A gripping mechanism 10 is attached to a mobile body to grip and convey a transportation article. The gripping mechanism 10 includes a pinion 20 provided so as to be rotatable about a rotation axis AX, and a first arm 12 and a second arm 14 disposed with the rotation axis being the center thereof so as to be separated from the rotation axis by the same distance in order to grip the transportation article. When the pinion 20 rotates in a predetermined direction, the first arm 12 and the second arm 14 move toward the rotation axis AX.
