Abstract: Soft picking tools for a pick and place robotic system are disclosed. A soft picking tool includes a body made of an integrated piece. The body includes stiff fingers located on a distal end of the body. The body also includes a portion of a soft-walled cavity configured to be deformed by application of a positive or negative pressure in the soft-walled cavity, leading to a motion of the stiff fingers, from a rest position, towards or away from a medial axis of the soft picking tool. The soft picking tool also includes one or more fingertips, where at least one of the stiff fingers includes a fingertip embedded on its distal end. The single-piece design and fingertips enable increased robustness, a reduced footprint, large gripping and spreading forces, and more efficient cluttered and flush grasping.

Abstract: Magnetic coupling mechanisms for robotic arm end effectors are disclosed. In particular, a magnetic coupling mechanism couples a detachable tool, such as a suction gripper, to a tool changer base of a robotic arm tool of an end effector. Magnetic coupling between the robotic arm tool and the detachable tool allows for breakaway when a sufficient force is applied to the robotic arm tool and/or the detachable tool to separate the two. The decoupling may be achieved via a tool rack. An exemplary system for coupling a detachable tool to a motion device includes a first magnetic ring affixed to a distal end of the motion device, where an inside of the first magnetic ring forms a first hollow chamber; and a second magnetic ring affixed to a proximal end of the detachable tool, where an inside of the detachable tool forms a second hollow chamber.

Abstract: A structural load cell case for a pick and place robotic system that prevents torsion, bending, and overloading from damaging sensors is disclosed. The structural load cell case includes a base, an inner tube that houses the load cell, and a roller sleeve outside the inner tube. The base is adapted to connect to a load and includes a compression spring interfaced with a first part of the load cell. The roller sleeve includes a plurality of roller bearings in contact with the inner tube. The inner tube is free to slide along an axis of the roller sleeve up to pre-determined limits, but is constrained from rotating or translating in directions other than the axis of the roller sleeve.

Abstract: A compliance mechanism for a pick and place robotic system comprising: a motion device, an end effector coupled to the motion device, wherein the end effector comprises a sheath structure, a rod, wherein the compliance mechanism is configured to: when the distal end of the rod is in not contact with an object, causing the distal end of the rod to move responsive to movement of the motion device, and when the distal end of the rod is in contact with an object and the motion device moves toward the object, causing the distal end of the rod to remain stationary by causing the sheath structure to move along a longitudinal direction of the rod.

Abstract: The present disclosure generally relates to pick and place robotic systems. An exemplary system for orienting an object comprises: a scanner configured to detect a label on the object; an upper conveyor belt; a flipping conveyor belt located at an end of the upper conveyor belt, wherein the upper conveyor belt is configured to transport the object toward the flipping conveyor belt, wherein the flipping conveyor belt is configured to, in a first orientation or position, rotate and exert a frictional force on the object to reorient the object while the object is in contact with the upper conveyor belt, wherein the flipping conveyor belt is configured to, in a second orientation or position, allow the object to drop off the end of the upper conveyor belt.

Abstract: The present disclosure generally relates to pick and place robotic systems. An exemplary apparatus for vacuum-gripping a deformable bag comprises: a primary chamber, wherein a proximal end of the primary chamber is connected to an air flow source, and wherein the primary chamber is configured to, upon an activation of the air flow source, receive a portion of the deformable bag via a distal end of the primary chamber; a secondary chamber surrounding the primary chamber, wherein the secondary chamber is connected to the primary chamber via a plurality of connections to allow for air passage, and wherein the activation of the air flow source causes a lateral wall of the primary chamber to grip the portion of the deformable bag via pressure differential between an inside of the deformable bag and the secondary chamber.
