ABSTRACT:
Apparatus and method for releasably connecting first and second objects, wherein a magnetic end effector may include at least one elongated pin member (10) a proximal end of which is connected to the first object (1) and the distal end of which may be inserted into a receiving portion (4) in the second object (2). Latch members (16) are carried by the pin member (10) for radial movement between retracted and expanded positions for releasing and locking, respectively, first and second objects (1, 2). A plunger member (20) carried by the pin member (11) is axially moveable between first and second positions. In the first plunger position, the latch members (16) are located in the expanded (locked) position and in the second plunger position the latch members (16) are released for movement to retracted or unlocked position. Magnetic end effector (30) is provided for releasable attachment to the first object (1) and for moving the plunger member (20) to the second position, thereby releasing the first object (1).
