Week 15: 11/28 - 12/5

This week's progress: -> Finalized the design for the motor's case -> Made sure our design didn't interfere with other teams' -> Found a place to buy aluminum stock for a good price if we need to have to buy the materials for the case ourselves Future progress: -> Run FEA analysis on the new shaft design and motor case. -> Find a manufacturer for the cases -> Finish the Final Report for the semester

Week 14: 11/21 - 11/28

This week's progress: Prototype progress: There were some complications getting our prototype 3D printed with MEP, but we were able to figure it out and present 2 different concepts during our presentation. Machine shop progress: SJSU's central shop has not replied to our inquiry, so we have looked into other machine shops that would manufacture our motor casing. We have a couple of shops on our list with the invoice and time needed to complete the job, but we would like to look into more shops before finalizing. Material progress: From previous week, Dr. Furman agreed on Aluminum as our material, we did some research online to get a rough estimation of the price of aluminum stocks. For a budget price below $500, we will be getting Aluminum 2024-T351 and Aluminum 6061-T6511. Both types are good for machining and can withstand high load.   However, after speaking with several shops, we will not need to order our own material. Certain machine shops will order t...

Week 13: 11/14 - 11/21

This week's progress: CAD Drawings: We are done with the new shaft design and the potential designs for the motor case. Originally, we have one case design that we agreed on, which is a metal case that goes over the whole motor case that we are going to receive from XOFO. However, we also made an alternative design that only goes over the motor itself. Both of these designs are going to be presented on Presentation #3. Prototype progress: Since all the CAD models have been completed, we are going to start sending the STL files to MEP for 3D printing. We are planning to have these 3D prints ready before the last presentation so that we can present them to the rest. Machine shop progress: We talked to SJSU's Central Shop as recommended by Dr. Furman. We have sent a service inquiry to them, but have not received any replies from them. We are planning to visit them as soon as possible to start an early prototyping. Material progress: -> Since Dr. Furman agreed on Alu...
