Week 02/20 - 02/27

Week 3 of the meeting was mainly to discuss the poster and presentation. Since most CAD designs are pretty much done now, we are waiting for the machined parts to be done. Machine parts will most likely be done by end of March, but there will be 3D printed ones for us to keep. Throughout the week, I researched on how to test a motor, including finding motor torque, torque constants, voltage, currents, etc.

Week 02/13 - 02/20

The second week of the meeting was going like usual. There was a meeting with the overall groups about Makers Faire, and there was a small talk provided by a guest speaker. Within the Motor's team, we got to a conclusion for our CAD designs and we sent the drawings to the machinist that we have reached out and contacted. The update given by the machinist is that we will be getting the case early March. The plan after receiving the case is that we will be testing the motor to find the torque, maximum speed, current it needs, and voltage it needs.

2nd semester Week 02/06 - 02/13

During the first week of the meeting, there was nothing much going on because everyone was busy moving in from the old Spartan Superway building. However, after finalizing the moving in, the team and I decided to pick a table in the room that will be used for our regular meeting table. I also helped the team in designing the poster that was required by Prof. Furman. Other than the poster, the team and I discussed future plans about we have o do, and the main focus of the semester. We came up with ideas such as measuring the actual dimensions of the motor and finalize our CAD designs, test motor once the Controls team are done with it, and follow up with the machinist

12/02 - 12/09

As for the last week of the semester, the motor team is pretty much on track with the time schedule. Our main dependency is the motor itself, as we are waiting for it to arrive any time within the next week. Since this week is the last meeting, we decided to split up tasks that we can do throughout the break. Referring to the team's Gantt Chart, I will be looking for machine shops around the South Bay and compare service quotes from them. Then, if the machinists do not approve the materials that we are planning to use, I will be researching other materials that might not cost too expensive.

11/26 - 12/02

Progress:

This week's progress began with the completion of CAD drawings for both the motor case and shaft. We have two design of the motor case, a case that goes over the original motor case, and an alternate design of a case that goes over the motor itself. Then, the CAD drawings were sent to the MEP for 3D printing. The small scale version of the prototypes were then used for presentation during the third presentation. We also presented our last presentation last Wednesday, 11/28.

Several future tasks that we have to complete are seeking professional help from machine shops for manufacturing our full scale version of the prototypes. Our aim is to manufacture the prototype before the spring semester starts. Also, we looked into materials that might be suitable for manufacturing. We searched into MetalsDepot and found that the aluminum stocks for both the motor case and shaft will roughly cost around $400. The types of aluminum stock that are going to be use are the Aluminum 2024-T351 and Aluminum 6061-T6511.

11/19 - 11/25

Progress:
- KBL controllers received and already given to the controls team.
- Motors are expected to arrive early December.
- Shaft design completed.
- Motor case design completed.

Machining progress:
- We talked to Dr. Furman about recommendations on machine shop:
- He suggested the Central Shop at SJSU's College of Engineering.
- We are in contact with Central Shop to start a service request, but we are also looking for any other potential machine shops for back-ups.

Material progress:
- We looked into what material our shaft and case would be. We discussed with Dr. Furman about this, and we came to an agreement of using aluminum as the material for shaft and case. I did some research on the price range of the material cost, it was around $500. With this budget, we will be getting Aluminum 2024-T351 and Aluminum 6061-T6511. Both types are good for machining and can withstand high load.

Next week's assignment:
- Start working on Presentation #3
- Start 3D printing prototype.

11/12 - 11/18

Progress:
- KBL controllers received and already given to the controls team.
- As of now, we are still waiting for the motor to be shipped. We received a confirmation from the company that expected delivery date should be early December.
- Shaft design is almost completed but still need some finalization.

Tire progress:
- I looked into airless tire options as our wheel, but our team decided to not use airless tire, instead, we are designing a rounded steel case that will house the motor and become our wheel.
- The CAD design for the case of the motor is also in progress.

Machining progress:
- We asked recommendations from Dr. Furman, and we were recommended Central Shop by him.
- We are still finding some other places for back up.

Next week's assignment:
- Continue CAD for new shaft
- Continue CAD for case housing
- Find materials for case and shaft
- Finalize on machining company
