END EFFECTOR TOOL CHANGER FOR PICK AND PLACE ROBOTIC SYSTEMS

End effector tool changers for a pick, sort, and place robotic system are disclosed. The end effector tool changer comprises an arm attachment portion, a plurality of engagement mechanisms, wherein each engagement mechanism comprises a first part and a second part, and wherein the first part and the second part of the engagement mechanism are selected from the group consisting of a pin and a pinhole; a robotic arm attachment portion, comprising a first plurality of magnets and a first plurality of first parts of the plurality of engagement mechanisms; and a tool attachment portion, comprising a second plurality of magnets and a second plurality of second parts of the plurality of engagement mechanisms. The end effector tool changer has greater mechanical stability, prevents accidental disconnection of the tool, and prevents unintentional rotation of the tool.
