Abstract: The system (50) includes at least one tread (52) secured to a tread drive means (54) for moving the tread (52) in a direction of a tread work-axis of motion (58) adjacent an object (78) to be moved. A head (57) is secured to the tread (52), and the head (57) includes a device (66) for grabbing the object (78). The head (57) selectively moves in at least a direction opposed to the tread work-axis of motion (58) and at a rate of speed at least the same as the rate of speed the drive means (54) moves the tread (52) in the tread work-axis of motion (58) direction to thereby achieve a net-zero motion relative to the object (58) to facilitate picking and placing the object (58). A plurality of treads (52) with such heads (57) may be secured in an endless loop (56).

Abstract: A desiccant container (10) includes a cylindrical body (12) having a first end (14) and an opposed second end (16). The cylindrical body (12) defines a desiccant chamber (18) within the cylindrical body (12) for holding the desiccant material within the chamber (18) between the first and second ends (14, 16). The cylindrical body (12) is made of a flexible, gas permeable, liquid impermeable material. A first disk (20) is secured adjacent the first end (14), and a second disk (22) secured adjacent the second end (16) to facilitate closing of the ends (14, 16) and to support maintenance of a cylindrical shape of the container (10) during usage of the desiccant container (10) in high-speed automated packaging machinery.

Abstract: A multi-head robotic system capable of delivering numerous robotic devices to a task site is disclosed. A number of robotic devices perform tasks simultaneously, thus tasks can be completed quickly. Each individual robot does not need to move at an extremely fast speed. The sequence in which the robotic devices arrive at or leave a task site is unlimited. The robotic delivery system is capable of “leapfrogging” robotic devices, or placing them randomly, at locations where they are most needed.

Abstract: The present invention comprises a material handling device and method for transferring material from one location to another. More specifically, the present invention relates to a device for placing material onto a pallet and/or removing material from a pallet. The device has a pedestal with a working arm pivotally connected to the pedestal. The working arm is driven by a horizontal motion actuator. Connected to the working arm and horizontal motion actuator is a cam follower that is received in a cam track on a cam track plate. The cam track plate can be easily removed and replaced with another plate with the cam tracks in a different arrangement. The horizontal motion actuator moves the cam follower along the cam track, resulting in movement of the working arm along a pre-selected path. At the end of the working arm is a material holder used for grasping and releasing the material to be transferred.

Abstract: A universal robotic end effector for use with a robot system is disclosed. The end effector is suited for transport by a high speed apparatus and, upon delivery to its destination, the end effector is capable of disengaging from the transport device. Once disengaged, the end effector is capable of independent operation. The end effector may rely on self-contained power and control signals, or may receive them from any workstation to which it is docked and locked, or from a remote source. Finally, the end effector is capable of reacquiring the moving transport device when it is ready to be moved to a new workstation.

Abstract: A mechanical closed loop robotic arm end effector positioning system which produces a precision reference frame with an associated workpiece fixture or other robotic manipulator system is disclosed. The positioning system results in decoupling of end effector operation from gross movement inaccuracies or vibrations of the robotic arm, thus allowing less precise robots to perform high precision tasks. The system includes a wrist assembly which is mountable to the robotic arm near the arm's distal functional end. The wrist assembly has a compliant member and a first positioning member connected thereto. The first positioning member includes a first docking arrangement. A second positioning member associated with the workpiece fixture includes a second docking arrangement. The first and second docking arrangements are sized and positioned to engageably mate within the robotic arm's resolution when the robotic arm attains a target position relative to the workpiece fixture.
