Part 1: Planning

Lay out the aluminum railing and mark three 36" spots. Once you have marked the aluminum you can begin cutting. Save the 12" aluminum remaining.

Part 2: Cutting

Using the band saw cut the Aluminum on those three tic marks made earlier.

Part 3: Clean up

Make sure to clean your work area.

Part 4: Assembly

Take your three pieces of aluminum (3' each) and 5 of your 3D printed triangles. First using your pliers take out your infill support, once that is completed take two of the aluminum pieces and lay it in a T-shape. Using the bolts and the 3D printed triangles secure the then T-shape. After that use the last 3' piece of aluminum and a 3D printed triangle to secure the aluminum vertically as seen in the picture.

• Part 1: Cut PVC

Measure and mark your 4' pvc pipe at 6", 9", 12". After that using a circular saw to cut the pvc pipe at those measurements.

• Part 2: Forearm assembly

Using the drill press, drill 1/4" holes 1.5" away from each end of the 6", and 9" pvc pipes. Now take two 2" u-shaped brackets and attach it to the end of the 6", and 9" pvc pipes using 12 washers and two 3.5" metal screws for each end of the pvc as seen in the picture above. With this attach the two ends of the pvc with the brackets to the servo motor. Attach the 6" pvc pipe to the side of the servo motor away from the wires with the nuts and bolts as seen in the images. Finally use the nut and bolt to secure the blue handle to the pvc pipe and place the gripper in the blue handle.

Part 1: Construct Shoulder

The shoulder will consist of the two 6" U brackets and the yellow jacket motors. You will place the yellow jacket motors through the circular brackets on top of the U brackets. You will then attach the U bracket to one of the yellow jacket motors axial.

Part 2: Attach Shoulder

You will then attach the the U shaped bracket to the stand using the same method with the 3D printed triangles.

After this you will attach the robotic forearm to the axial of the other yellow jacket motor.
