The present application relates to lifting equipment for a waffle slab used in a construction. The lifting equipment comprises a main body bracket, a sliding member and a plurality of clamping mechanisms. The main body bracket has a through hole in a center thereof. The sliding member is slidably disposed in the through hole of the main body bracket and is slidable between a first position and a second position. Each of the plurality of clamping mechanisms comprises a clamping member and a connecting rod. The clamping member comprises a first end and a second end, wherein the first end is pivotally connected to an outer edge of the main body bracket, and the second end is configured to extend into a hole of the waffle slab for clamping the waffle slab. A proximate end of the connecting rod is pivotally connected to a lower end of the sliding member, and a distal end of the connecting rod is pivotally connected to the clamping member between the first end and the second end.

A drone payload device includes a remote drone arm and a control module. The remote drone are is coupleable to a drone. The remote drone arm includes a base, an arm, and a gripper. The base includes mounting hardware to couple to the drone. The arm extends from the base. The griper is coupled to the arm at an end of the arm distal from the base. The control module is coupleable to a drone controller. The control module is to provide a control signal to the remote drone arm to control a movement of at least one of the arm and the gripper.

A method for detaching or installing a rotor blade from or to a hub of a wind turbine includes positioning the rotor blade toward a ground location between a three o'clock position and a nine o'clock position. The method also includes mounting a mechanical arm to an uptower location of the wind turbine. Further, the mechanical arm includes a torqueing tool at a distal end thereof. Thus, the method also includes removing or installing, via the torqueing tool, each of the plurality of hub fasteners so as to detach or attach the rotor blade from or to the hub.

A multi-articulated manipulator composed of more than one hollow outer shell, joints to connect the outer shells to each other, a grasping member fastened for rotating movement with respect to the proximal outer shell, a claw transmission shaft to actuate the grasping member to rotate and an outer shell power transmission shaft to actuate the outer shells in to rotate independently from each other. The claw transmission shaft and the outer shell power transmission shaft respectively are composed of universal joints capable of rotating force and transmitting torque.

A gripping device configured as a robot tool or a robot hand includes two gripper fingers rotationally coupled to each other by a joint. The gripper fingers are pivotable about a rotational axis between a gripping position and a release position, the rotational axis being defined by the joint. An angle between the gripper fingers about the rotational axis is larger in the gripping position than in the release position. The gripper fingers are configured to reach through a through-hole in an object to be gripped from a first side of the object. The gripper fingers have an end piece at a distal end thereof, the end piece being configured to engage behind the object at a second side of the object opposite the first side along a length axis of the gripper fingers. The joint is fixed to a joint support extending from a main body.

A tray engine includes a vertical drive column, a rotation mechanism for rotating the vertical drive column, and an end effector attached to the vertical drive column. The end effector includes an end effector base attached to the vertical drive column. The end effector further includes a slide attached to the end effector base to support a tray, when present. The slide enables the tray to slide along a length of the end effector base. The tray engine includes a drive mechanism attached to the end effector base for moving along the length of the end effector base to enable the tray, when present, to slide linearly along the length and load or unload the tray to or from the slide.

A robotic arm mounted camera system allows an end-user to begin using the camera for object recognition without involving a robotics specialist. Automated object model calibration is performed under conditions of variable robotic arm pose dependent feature recognition of an object. The user can then teach the system to perform tasks on the object using the calibrated model. The camera's body can have parallel top and bottom sides and adapted to be fastened to a robotic arm end and to an end effector with its image sensor and optics extending sideways in the body, and it can include an illumination source for lighting a field of view.

A case packing system for loading articles into containers includes an article conveyor for conveying articles, a case conveyor for conveying containers, and first, second, and third bins. A first robotic mechanism moves articles on the article conveyor to the first, second, and third bins. A second robotic mechanism moves articles from the first, second, and third bins to containers on the case conveyor. A controller operatively coupled to the first robotic mechanism and the second robotic mechanism is configured to pick and place with the first robotic mechanism one or more conveyed articles into the first, second, and third bins, and grab and load with the second robotic mechanism one or more articles from the first, second, and third bins into containers on the case conveyor.

A gripper includes a base unit and finger units coupled to a protruding direction-side of the base unit. Each of the finger units includes a first link structure coupled to the base unit, a second link structure rotatably coupled to the first link structure, and a third link structure rotatably coupled to both the first link structure and the second link structure, and the second link structure includes a finger tip. When the finger unit is pressed in the protrusion direction, the finger tip is brought closer to the base unit in the protrusion direction by the first link structure. When the finger unit is further pressed in the protrusion direction, the finger tip is rotated to be oriented in a direction opposite to the protruding direction in a state in which the finger tip is oriented in a gripping direction that is a direction perpendicular to the protruding direction.
