According to one embodiment, a holding device includes: holding parts; a holding part opening/closing part that opens and closes the holding parts; a first sensor that detects a load received by the holding part; and a controller that controls an operation of the holding part. At least one of the plurality of holding parts includes a claw member displaceable along a length direction of the holding part, a second sensor that detects a displacement amount of the claw member, and a reaction force applying part that applies a reaction force corresponding to the displacement amount of the claw member to the claw member. The controller controls the operation of the holding part, based on a detection value of the second sensor when the displacement amount is equal to or less than a threshold value, and based on a detection value of the first sensor when the displacement amount exceeds the threshold value.

According to one embodiment, a gripping tool includes a gripper. The gripper is flexible. A granular material is provided in an interior of the gripper. The gripper is configured to grip a workpiece by being in close contact with the workpiece in a state in which an outer perimeter of the gripper is held, and by the interior of the gripper being depressurized.

Gripping tool and gripping system

According to one embodiment, a gripping tool includes a gripper. The gripper is flexible and includes a first portion contacting a workpiece, a second portion opposing the first portion, and a granular material provided between the first portion and the second portion. The first portion includes a concave portion and a convex portion. The concave portion is recessed in a first direction. The first direction is from the first portion toward the second portion. The convex portion is provided around the concave portion and protrudes in a second direction. The second direction is the reverse of the first direction. The concave portion has a groove having a ring configuration recessed outward from a center of the gripper.

According to one embodiment, a gripping tool includes a gripper, a sensor, a pump unit, and a controller. The gripper is flexible and has a granular material provided in an interior of the gripper. The sensor is connected to the interior. The sensor detects a pressure or a flow rate of a gas. The pump unit is connected to the interior. The controller performs at least a first operation of causing the gripper to contact a workpiece and causing the gripper to operate, and a second operation of separating the gripper from the workpiece and causing the gripper to operate. In at least a portion of the second operation, the controller sets a pressure of the interior to be different from a pressure external to the gripper.

In one embodiment, a fiber manufacturing apparatus has a discharge head which discharges a raw material liquid in which a polymer is dissolved in a solvent toward a collector, and a power source which generates a potential difference between the discharge head and the collector. The fiber manufacturing apparatus further has a recovery device, a cleaning device, and a moving device. The recovery device recovers the raw material liquid to be discharged by the discharge head. The cleaning device cleans the discharge head. The moving device moves the discharge head to any position out of a spinning position where the discharge head and the collector are opposite to each other, a recovery position where the discharge head and the recovery device are opposite to each other, and a cleaning position where the discharge head and the cleaning device are opposite to each other.

Fiber manufacturing apparatus and fiber manufacturing method

A robot hand device according to an embodiment includes extensible arms which can be extended and shortened, a drive motor, and at least one clutch. The extensible arms support an object to be carried and are capable of being extended and shortened. The drive motor extends and shortens the extensible arms. The at least one clutch are capable of transmitting power of the motor to at least one of the extensible arms selected among the extensible arms to extend and shorten the selected at least one of the extensible arms.
