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.

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.

Abrégé

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.
