1. In a robotic tool changing system which facilitates the automatic exchange of tools on an end of a robot arm, the combination comprising:

  • a robot adapter assembly for attachment to the end of the robot arm;

    a tooling adapter assembly for attachment to a fastener attaching tool;

    means for coupling said tooling adapter assembly to said robot adapter assembly;

    a first passage defining member associated with said robot adapter assembly, said first passage defining member having an entry port at a first end thereof and an exit port at a second end thereof;

    a second passage defining member associated with said tooling adapter assembly, said second passage defining member having an entry port at a first end thereof and an exit port at a second end thereof;

    a first feed tube for transporting fasteners from a source of fasteners to said entry port of the first passage defining member;

    a second feed tube for transporting fasteners from the exit port of said second passage defining member to the fastener attaching tool; and

    wherein the coupling of the tooling adapter assembly to the robot adapter assembly causes said first and second passage defining members to engage and define a passageway extending from said entry port of said first passage defining member to said exit port of said second passage defining member to allow a fastener to be transported from said source of fasteners through said first feed tube, said passageway and said second feed tube to the fastener attaching tool.
