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

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

11/5 - 11/11
Progress:
This week, my group mates and I get together to decide on purchasing the motor and controller:
- KBL controllers found and purchased [Approved by Dr. Furman]
- 3 Motors purchased [Approved by Dr. Furman]
Right now, we are waiting for the motor to be shipped from China.
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.
Shaft progress:
We are going to change our shaft design. We are designing a threaded axle that will connect one motor on each side of that shaft instead of designing a single shaft for each motor.

10/29 - 11/4
Last week's assignment:
- Work on presentation
- Presentation on 10/24
10/31:
My groupmates and I met on Spartan Superway Garage for our weekly meeting. We worked on the team blog together and assigned individual tasks to be completed by the end of the semester, such as deciding on controllers and getting an invoice for it. Continue working on the shaft drawing, as well as the housing of the motor, do more FEA analysis on both CAD drawings, and start ordering the motor from XOFO.
This week's assignment:
- Look into KBL controllers or any controllers by other companies that satisfy our requirements.
- Look into available airless tire options and how to attach it to our designed motor housing.
- Find a machining shop that can help manufacture our CAD drawings of the shaft and motor housing.
- Work on presentation
- Presentation on 10/24
