A gripper mechanism includes a pair of gripper jaws, a linear actuator, and a rocker bogey. The linear actuator drives a first gripper jaw to move relative to a second gripper jaw. Here, the linear actuator includes a screw shaft and a drive nut where the drive nut includes a protrusion having protrusion axis expending along a length of the protrusion. The protrusion axis is perpendicular to an actuation axis of the linear actuator along a length of the screw shaft. The rocker bogey is coupled to the drive nut at the protrusion to form a pivot point for the rocker bogey and to enable the rocker bogey to pivot about the protrusion axis when the linear actuator drives the first gripper jaw to move relative to the second gripper jaw.

A system connects an assembly with at least one actuator and at least one sensor to a controller. The assembly is guided by a handling apparatus. The controller includes a radio master spatially separate from the handling apparatus and has a sending and receiving unit. The assembly is supplied with supply voltage by the handling apparatus. In or on the assembly, the supply voltage is transformed into a direct current target voltage with the aid of a DC/DC or AC/DC transformer. The direct current target voltage supplies the sending and receiving unit of the assembly.

A method and apparatus for dispensing and retrieving products is provided. A system may include: a grasping head; first and second grasping members, each grasping member comprising: a top member; a post member; and first and second grasping fingers, where the first and second grasping fingers extend from the post member and are spaced apart from the top member by a predetermined distance, where the first and second grasping members are connected to the grasping head, where at least one of the first and second grasping members is movably connected to the grasping head, where the at least one of the first and second grasping members is movable relative to the other of the first and second grasping members.

Various examples are provided related to end effectors for use in, e.g., automation of sewing robots. In one example, among others, a compliant perimeter end effector includes a mounting bracket having a contact mounting flange, a plurality of compliant material contact elements coupled about a perimeter of the contact mounting flange. The mounting bracket can couple to a manipulator including, e.g., an industrial robot or other manipulation assembly. The compliant material contact elements can include a contact interface that can engage with a piece of material. The compliant material contact elements can precisely transfer material on a workspace with surface irregularities while equally distributing force to the material.

Two-phase gripper. The gripper reorients and grasps an object while being picked up. The gripper includes a parallel jaw gripper including a pair of opposed, two-phase fingers, each finger including a cavity covered by an elastic strip wherein the elastic strip includes a point contact. Closure of the jaws of the gripper on an object at a first relatively lower force results in contact with lower friction between the point contact on the elastic strip on the fingers and the object allowing the object to rotate under gravity as the gripper is raised. Thereafter, closure of the jaws of the gripper on the object at a second relatively higher force causes the elastic strip to receded into the cavity resulting in multi-point contact with higher friction between the fingers and the object to securely grasp the object. In a preferred embodiment, the cavity is a Y-shaped groove and the object is cylindrical or prismatic.

A wafer handing assembly comprising a center hub supporting a vertical non-contact lifting head and at least one radially extending and radially retracting wafer engaging mechanism having a surface to engage a wafer at a peripheral edge of the wafer, where the peripheral edge is a corner edge or a side edge. In some implementations, the wafer engaging mechanism has a foot on which the wafer edge is supported.

A gripper mechanism includes a pair of gripper jaws, a linear actuator, and a rocker bogey. The linear actuator drives a first gripper jaw to move relative to a second gripper jaw. Here, the linear actuator includes a screw shaft and a drive nut where the drive nut includes a protrusion having protrusion axis expending along a length of the protrusion. The protrusion axis is perpendicular to an actuation axis of the linear actuator along a length of the screw shaft. The rocker bogey is coupled to the drive nut at the protrusion to form a pivot point for the rocker bogey and to enable the rocker bogey to pivot about the protrusion axis when the linear actuator drives the first gripper jaw to move relative to the second gripper jaw.

A vegetable transplanting device includes a robotic arm, a positioning ring fixedly disposed on an outside of the robotic arm, and a transplant assembly connected to the robotic arm. The transplant assembly includes: a motor fixedly disposed at an end of the robotic arm; a fixing frame fixedly mounted on a side surface of the positioning ring away from the robotic arm; a worm screw fixedly disposed at an output end of the motor; first fixing rods fixedly disposed and passing through the fixing frame; worm gears, each rotatably installed on an outside of one of the first fixing rods, the worm gears being engaged with the worm screw by teeth; connecting rod assemblies, each rotatably installed on the outside of at least one of the first fixing rods; and clamping members, each rotatably connected to one end of the corresponding connecting rod assembly away from the fixing frame.

A robot includes a hand that grips an object and a control unit that operates the hand, the hand includes fingers that are able to grip the object at four or more contact points, and an object of which a metallic tone index is equal to or higher than 5 is gripped with the hand.

An example injection needle positioner includes: first and second mounting brackets; a first grip, comprising: a first aperture configured to interface with the first mounting bracket; and a first grip face on a lateral side of the first grip, the first grip face comprising: a first section toward a first end of the first grip and having a first profile; and a second section toward a second end of the first grip, relative to the first section, and having a second profile different than the first profile; and a second grip, comprising: a second aperture configured to interface with the second mounting bracket; and a second grip face on a lateral side of the second grip.
