Problem Statement
''In one or two sentences, describe the project that your group will be working on. Identify what CDIO phase (Conceive, Design, Implement, or Operate) your group will complete in this project cycle.''

Project Plan
Briefly describe your group's plan for the next 4 weeks, including major tasks that will be completed each week.

Week 1 Narrative
''During this week, i have been assigned once again to work on the automatic shaker table and get this project completed. Since the entire week was spring break our work isn't much but we did get what we could to try and get started on finishing the project. Since this week was spring break, many setbacks came up since we couldn't contact each other over break because nobody could get together and help work on the table. So i did what i could without my group and so i came up with a list of what we need to add to the table to get it finally finished. At the top of the list is the main goal of implementing the motor with it able to move in one direction to be able to spin which will move the table parallel back and forth. Next biggest issue is the gear that will be rotating causing the table to be moved. This gear needs to be a certain size diameter to move the table only so much (about 2in); plus making sure everything is fitted perfectly and fastened down. The last major big problem is finishing the frame to the automatic shaker table. It needs the second manual shaker table to be constrained to the wood itll be resting on and the box for the electrical components needs a top to cover all the gearing and wires. Than after that piece is made and secured, a hole needs to be drilled in the front of the box so that the armature can come through and be attached to the moving platform. These main problems that i came up with are standing in our way from finally being able to have a working automatic shaker table. Once all these problems are met accordingly and the appropriate way by our team this entire project will be able to move onto the next phase.

Week 2 Narrative
''For the past week working on the automatic shaker table it has progressed to almost being completely finished, all that remains is the electrical components. My task this week was to work on the hardware of the shaker table. We already made our frame for the second manual shaker table to be mounted on along with one side containing the electrical wiring; now the second manual shaker table is screwed in all four corners of the pvc pipe base to the long 1x3in boards stretching out of the electric box. Once mounted the manual shaker table will have no free movement at all from the wooden base. Next step was to cut a hole in the front of the box to be able to attach the 7in armature from the moving platform to the big gear inside the electrical box. The cut was needed in the middle of the front side of the box because we planned to attach the armature in the center of the platform to shake the board evenly across the dowel rods. Once the cut was done we can have the armature move with ease up and down to move the platform back and forth. All that is left to work on is the electrical components that will power a motor spinning a gear with the armature attached to it. Once we have the electrical wiring and a top for the box on the wooden frame the automatic shaker table will be completed.

Week 3 Narrative
''With the second to last week working on the automatic shaker table, all that is left is two major problems. The first problem, which is my task was my task, find a way to attach the armature to the moving platform allowing the armature to move in an up and downwards motion. The other conflict was all the electrical wiring configuration and finding the huge gear to move the platform. For my task i needed to come up with an assembly to attach the armature too. This kind of assembly needed to allow the armature to be able to move in an up and downwards motion while still being attached to the moving platform. With this assembly i needed two pieces of framing to be screwed down to the moving platform about a quarter of an inch apart. The reason for this is so armature isn't sliding every where when the machine is turned on. Once screwed down there will be a top hole in the faming so an axel can be threaded through those holes and the armature itself. After the axel is fitted rubber stoppers should be placed on both sides of the axel so it doesn't slide out of the framework. This idea allows the armature to move the board with ease back and forth on top of the dowel rods. One of the problems has been confronted all that is left should be the electrical wiring with the huge gear. But that problem is being taken on by my other group members. The automatic shaker table is on its final details and should be running very shortly.

Week 4 Narrative
The past week working on the automatic shaker table, my task was working on the automatic shaker table with kyle. So what we did for the last week was try to put the electrical wiring on to the automatic shaker table and see if the platform would move or not. The first step we took to start off was mounting the armature down to the moving platform. We found two wooden right triangles that are two inches in length and should serve as base to put a long 3 in screw through both of them so the armature can be fitted through in between both the triangles. Once the armature is fastened in between the two triangles, the triangles need to be securely fastened to the moving platform. AS i was holding the triangles down kyle screwed them in at the angle of the triangle and surely enough the armature is ready to be attached to the big gear on the motor. With the armature fastened to the moving board on one side, the other side needs to be attached to the big 4 in gear that will cause the board to fully move back and forth. I took the gear and drilled a 3/8 in hole in the outer edge of the gear so a bolt can be fed through the gear and armature, than capped with a wing nut at the end of the bolt so the armature doesn't fall off. Afterwards, we took what we made and attached the gear to the motor which was wired to the arduino. With this all hooked up we started testing to see if the motor could move the entire board by spinning the gear with the armature; but after our tests the motor didn't have enough power to be able to move the platform. With our first testing a failure we tried using a bigger stepper motor that was apart of a car's windshield wiper. The problem with this motor is it has six wires compared to the smaller ones four. So we were not able to hook up the motor in the correct fashion in order for it to work for us. With the end of our project we have all the work done except the motor needs to be changed in order for the machine to be an automatic shaker table versus a manual shaker table. For the next group taking on our project all the hardware and electrical configurations are finished and set, all it needs is some minor touches done to it for a completely finished product.
