In a robot (industrial robot) system, a robot holds a workpiece by pinching the workpiece between movable claws. A controller, which controls the robot, includes a host controller that controls the robot to perform a positioning operation for positioning the hand to a grip position and a gripping operation for displacing each of the movable claws toward each other at the grip position. In the controller, a machine learning device acquires stop reference data set for gripping of the workpiece, distance data indicating a distance between each of the movable claws of the hand positioned at the grip position and the workpiece, and comparison data indicating a deformation amount of the workpiece before and after the gripping operation. The machine learning device performs machine learning using such acquired data, resulting in constructing a model used for setting an operation mode of the gripping operation.

An apparatus for gripping an object includes a base element and at least three gripping arms which are mounted on the base element. The at least three gripping arms are each movable independently of one another relative to the base element and the object can be picked up by the at least three gripping arms. The at least three gripping arms each have a hook-shaped gripping tool.

It is an object of the present invention to provide a weighing device in which dropping of articles from gripping means and reductions in weighing precision are suppressed. In a weighing device (100), when at least one of an operation state of grippers (30) and weighing results from weighing units (40) fulfills any condition from among “a weight value of articles (A) weighed by the weighing units (40) not being a preset target weight value,” “an operating distance in an operation in which the articles (A) are held by gripping members (32) being greater than a prescribed range,” and “the operating distance in the operation in which the articles (A) are held by the gripping members (32) being less than the prescribed range,” the articles (A) gripped by the grippers (30) are returned to an article group accommodation container (52) by a control unit (70) without said articles (A) being discharged to a discharge chute. As a result, a situation where the grippers (30) operate while still holding “articles for which the weight value is not the target weight value” is avoided.

Disclosed is a rescue robot for searching trapped persons for firefighting, including a mobile base. Mobile rollers with self-locking mechanisms are mounted at a bottom of the mobile base, a machine mounting seat is fixed to the mobile base, a rotating column is arranged at the top of the machine mounting seat, a driving motor is mounted at a bottom of an inner cavity of the machine mounting seat, a right output end of the driving motor is sleeved with a driving bevel gear, a bottom of the rotating column penetrates through a top of the machine mounting seat and is sleeved with a driven bevel gear, the driving bevel gear and the driven bevel gear are mutually meshed, a portion of an outer wall of the rotating column is fixedly sleeved with a fixed seat, left and right sides of the fixed seat are symmetrical bridge cranes.

A bag-shaped actuator system includes: a bag-shaped actuator including an airtight bag member and flowable particulates filled in the bag member; a bag-member communication pipe configured to communicate with an inside of the bag member; a low-air-pressure-source communication pipe configured to communicate with a low air pressure source; a high-air-pressure-source communication pipe configured to communicate with a high air pressure source; a switching mechanism configured to perform switching between communication destinations of the bag member such that the inside of the bag member communicates with any of external air, the low-air-pressure-source communication pipe, and the high-air-pressure-source communication pipe via the bag-member communication pipe; and a switching controlling portion configured to control the switching between the communication destinations by the switching mechanism.

An air chuck includes a chuck unit including a pair of fingers that capable of being freely opened and closed, an operation unit that includes an operation mechanism, which opens and closes the pair of fingers, connection mechanisms for attaching the chuck unit to the operation unit such that the chuck unit is freely attachable and detachable to and from the operating unit, and a locking mechanism that locks the pair of fingers such that the pair of fingers are capable of being freely opened and closed when the chuck unit is attached to the operation unit and such that the pair of fingers are not able to be opened or closed when the chuck unit is detached from the operation unit.

An example apparatus of the present disclosure may include an end effector. The end effector may include a pair of actuator-driven fingers that each include a compliant tip. The compliant tips may be used to scoop underneath items as part of item manipulation.

Object manipulation in warehouses and logistics facilities is a challenging task because of the unstructured environment. The unstructured environment can have items/objects with different form factors, weight, shape, and size. Traditionally, multiple robots have been used to handle for specific task to be performed by an individual robot which requires high floor. This leads to higher cost and infrastructure. Embodiments of the present disclosure provide a gripper apparatus that addresses a single gripper design handling multiple parcels, wherein the apparatus consists of ‘m’ fingers parallel to each other and can be independently controlled through actuators, each finger has a force sensors feedback and also actuators which are controlled with force. Each finger comprises a linear slider for actuation for gripping objects and wherein bottom fingers are moved to provide enough gravity support. Further, apparatus comprises bellows attached to each finger end for grasping object using pneumatic grasping mechanism.

A pair of grippers movable with respect to each other and each of which comprising a body presenting an annular ring oriented perpendicular with respect to a longitudinal length of the end effector. The annular ring of each gripper of the pair of grippers is oriented facing each other so that a space between the annular ring of each gripper of the pair of grippers increases and decreases as the pair of mounting blocks move laterally towards and away from each other.

An automatic picking fixture device: a fixture locked with a mechanical arm and includes a coupling orifice, a motor, a rotor, and a gear. The fixture includes four elongated orifices and two movable holders. The two movable holders have four through orifices corresponding to the gear, four passing orifices, and two toothed sections received in the four through orifices and meshing with and driving the gear. The four passing orifices of the fixture is configured to lock with the four pneumatic cylinders or four servo motors, and the four pneumatic cylinders or the four servo motors are configured to push four jaws outward or inward, the four jaws include four symmetrical clamping grooves configured to clamp at least one material. The four racks are fixed on the top of the fixture, and a respective rack has two rollers rolling along a respective elongated orifice.
