The lead screw and nut assembly is operably connected to the drive system such that rotation of the nut drives the lead screw upwardly and downwardly relative to the housing. The scoop assembly is operably connected to the lead screw. The scoop assembly has an open position and a closed position and movement of the lead screw downwardly responsively moves the scoop assembly from the open position to the closed position. ## Claims ### Claim 1 A tooling arm comprising: a housing; a drive system; a lead screw and nut assembly having a lead screw operably connected to the drive system such that rotation of a nut drives the lead screw upwardly and downwardly relative to the housing; and a scoop assembly connected to the lead screw, the scoop assembly having an open position and a closed position and movement of the lead screw downwardly responsively moves the scoop assembly from the open position to the closed position. ### Claim 2 (depends on 1) The tooling arm as claimed in claim 1 wherein the scoop assembly acts as a four bar link mechanism. ### Claim 3 (depends on 2) The tooling arm as claimed in claim 2 wherein the scoop assembly includes a pair of scoops, a pair of links and a shuttle, each scoop pivotally attached to the shuttle, each link is pivotally attached at one end thereof to a bracket and the other end thereof to one of the pair of scoops. ### Claim 4 (depends on 3) The tooling arm as claimed in claim 3 wherein the bracket is attached to a lower end of the lead screw. ### Claim 5 (depends on 4) The tooling arm as claimed in claim 4 wherein shuttle includes a stopper which engages a block connected to the housing. ### Claim 6 (depends on 5) The tooling arm as claimed in claim 5 wherein the drive system includes a motor and gear head assembly. ### Claim 7 (depends on 6) The tooling arm as claimed in claim 6 wherein the housing includes an upper mounting plate and the motor and gear head assembly is attached thereto. ### Claim 8 (depends on 1) The tooling arm as claimed in claim 1 wherein the lead screw and nut assembly includes a guide tube having a slot therein and wherein the lead screw includes a screw pin extending through the lead screw and its motioning is limited by the slot. ### Claim 9 (depends on 1) The tooling arm as claimed in claim 1 wherein the drive system includes a motor and gear head assembly. ### Claim 10 (depends on 9) The tooling arm as claimed in claim 9 wherein the housing includes an upper mounting plate and the motor and gear head assembly is attached thereto. ### Claim 11 (depends on 10) The tooling arm as claimed in claim 10 wherein the lead screw and nut assembly includes a guide tube having a slot therein and wherein the lead screw includes a screw pin extending through the lead screw and its motioning is limited by the slot. ### Claim 12 (depends on 1) The tooling arm as claimed in claim 1 where the lead screw is rotatably connected to the nut which is driven by a motor via a pair of meshing spur gears. ### Claim 13 (depends on 1) The tooling arm as claimed in claim 1 wherein the tooling arm is operably connected to a mobile robot.
