A hand mechanism grips an object more favorably, regardless of the attitude and surrounding conditions of the object. When an object is to be gripped by a hand mechanism having three or more finger portions, at least one finger portion among the three or more finger portions functions as a state-altering finger portion for altering the attitude or the position of the object while contacting the object, and at least two finger portions among the finger portions other than the finger portion functioning as the state-altering finger portion function as gripping finger portions for gripping the object in a state where the attitude or the position has been altered by the state-altering finger portion.

A refuse vehicle includes a chassis, multiple tractive elements, a reach assembly, and a lift assembly. The multiple tractive elements are coupled with the chassis and configured to support the refuse vehicle. The reach assembly is coupled with the refuse vehicle. The lift assembly is coupled with the reach assembly. The lift assembly includes a track and a fully-electric grabber assembly. The track includes a straight portion and a curved portion. The fully-electric grabber assembly can ascend or descend the track and includes a carriage, a first grabber arm, a second grabber arm, and an electric motor. The carriage is configured to movably couple with the track. The first grabber arm and the second grabber arm are pivotally coupled with the carriage at opposite ends of the carriage. The electric motor is configured to drive the first grabber arm and the second grabber arm to rotate relative to the carriage.

A gripping device comprises an electric linear motor having a motor stator and a motor slider which is movable in a longitudinal direction, a first gripper finger and a second gripper finger, a redirecting mechanism which is coupled to the motor slider as well as to at least one of the first and second gripper fingers, and a constant force generator having a stator and a slider which is movable relative to the stator in the longitudinal direction. The stator has a magnetically conductive or permanently magnetic stator region, and the slider has a permanently magnetic or magnetically conductive slider region. In a gripping position, the slider region and the stator region only partly overlap in the longitudinal direction, while in an open position, the slider region and the stator region do not overlap in the longitudinal direction.

A finger device including a finger segment, a finger base, a first steering control mechanism, a first actuator, a second steering control mechanism, a universal joint and a second actuator is provided. The finger base is connected to one end of the finger segment, and the first steering control mechanism is disposed on the finger base. The first actuator is configured to provide a first moment to the first steering control mechanism, so that the finger segment and the finger base have a degree of freedom in a first moving direction. The second steering control mechanism is disposed on the finger base. The second actuator is configured to provide a second moment to the universal joint. The universal joint is rotatably connected between the second actuator and the second steering control mechanism, so that the finger segment has a degree of freedom in a second moving direction.

There exists a limitation while designing tugger device with latching area for gaining a specific orientation of a powered vehicle and orientation of unpowered trailers. This disclosure relates generally to an automated carrier tugger mounted on an autonomous mobile robot (AMR) for tugging a carrier. The automated carrier tugger includes a rotary joint unit, a swivel adaptor unit, and a tugging unit for clamping a horizontal bar. The rotary joint unit includes a vertical fixed shaft and plurality of integral pipes are integrated with a pipe mounting plate at one end. The swivel adaptor unit include the pipe mounting plate mounted onto the plurality of integral pipes and a male spherical joint integrated with a swivel adaptor plate. The tugging unit includes a single rear clamp and a plurality of front clamps with a plurality of flanges mounted onto a plurality of horizontal axis slides to move at required direction.

A robotic surgical tool comprises a stage assembly and a core assembly removably mountable to the stage assembly. The stage assembly may comprise a lead screw and at least one spline extendable between first and second ends of the stage assembly, and a nut rotatably mounted to the lead screw to translate between the first and second ends upon rotation of the lead screw. The core assembly may comprise a drive housing that is movably mountable to the stage assembly to translate, with the nut, between the first and second ends of the stage assembly. The surgical tool may also comprise a shroud assembly having a primary shroud and a secondary shroud, the primary shroud at least partially enclosing the core assembly when installed on the stage assembly, and the secondary shroud being movable between a first position, where the secondary shroud occludes an opening in the primary shroud, and a second position, where the opening in the primary shroud is exposed. The secondary shroud may be pivotally attached to the primary shroud at a hinge. The secondary shroud may be slidingly attached to the primary shroud, such that the secondary shroud is circumferentially revolvable relative to the primary shroud between the first and second positions. The secondary shroud may be slidingly attached to the primary shroud, such that the secondary shroud is axially slidable relative to the primary shroud between the first and second positions.

A door opening device comprising a multi-directional head and a telescoping pole is provided. The multi-directional head allows the operator to choose the angle when opening the door and the telescoping pole allows the operator to remain at a distance away from the doorway while operating the doorknob. By allowing an operator to remain around a corner when opening a door, an armed and cornered individual is less able to harm the operator by shooting through the door.

A gripper apparatus including a gripper frame and a gripper beak; an actuation mechanism for actuating the gripper beak; a clamping force generator biased to exert a clamping force on the gripper beak; a transmission mechanism including an input member that is vertically displaceable with respect to the gripper frame, wherein the transmission mechanism engages the actuation mechanism such that a high position of the input member corresponds to a closed position of the gripper beak while a downward displacement of the input member corresponds to a transition of the gripper beak to an open position; a vertically displaceable carrier coupling device that in a lower rest position presses down on the input member; and a latch mechanism, preferably of alternate push-push type, for holding the gripper beak in its open position.

A controller for a commissioning device for storing piece goods such as medicinal packages is provided. The controller includes a delivery table that extends in a first direction, two elongated clamping jaws disposed above the delivery table, the jaws having clamping surfaces that face one another, and a clamping jaw guide apparatus with a frame structure, at least one first and one second guide which are separated from one another in the first direction and extend in a second direction, and at least four clamping jaw carriages which are coupled to the guides and driven in the second direction. Two clamping jaw carriages each are associated with a guide and at least two clamping jaw carriages separated from one another in the first direction are coupled to one clamping jaw, respectively.

A joint structure for a robot including a four-link mechanism, in which an elastic member expands and its restoring force increases as a finger is bent, and a distance between a second straight line passing through a center of a second rotation shaft and a fixed point at which the other end of the elastic member is fixed to the third link is equal to or longer than a distance between a fourth straight line passing through a center of a first rotation shaft and a fixed point at which one end of the elastic member is fixed to the second link, the second straight line being perpendicular to a first straight line passing through centers of second and fourth rotation shafts, and the fourth straight line being perpendicular to a third straight line passing through centers of first and third rotation shafts.
