Week 12: 11/8 - 11/14

This week's progress: -> Our team received the controller that we purchased from KBL and got it delivered to the controls team. -> We are done with the new shaft design (will be presented during presentation #3). As of now, we are working on the drawing of the motor case. We went over several potential designs with Dr. Furman and we came to an agreement on one of them. -> We are aiming to finish the CAD design for the motor case by this week. Once done, we will send the drawings to MEP for 3D printing. -> We talked to Dr. Furman about recommendations on machine shop, and he suggested the Central Shop at SJSU's College of Engineering. We contacted Central Shop to start a service request, but we are also looking for any other potential machine shops for back-ups. -> 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. We are also

Week 11: 10/31 - 11/7

This week: All decisions were made with Dr. Furman's approval: -> Purchased one KBL controller for controls team to run the necessary tests. The controller will arrive on Thursday 11/8 by 10:30 AM. (Paid a total of $100) -> Purchased 3 XOFO motors. Motors will take 3 weeks to be manufactured and shipping will take approximately a week. We expect to have motors before the end of the month, most likely after Thanksgiving. (Paid a total of around $700) -> We are scrapping previous CAD design of the shaft. Project scope has been changed by Dr. Furman. He preferred us not to take apart the motor to replace the shaft and casing. Dr. Furman was fine with leaving the double-sided shaft sticking out, which made our team's decision easier. -> We are not doing any changes to the motor that we purchased, as requested by Dr. Furman. Originally we are planning to design a housing for the motor to attach airless tire on it. Instead, we are designing a rounded steel case

Week 10: 10/24 - 10/31

This Week: -> The Motor Housing is being designed. A big concern is making sure the wheel will fit the track, but guideway states the 3.5 inch thickness is fine. -> Research is being done on options for tires, we want a tire that's at least 1 inch tall, to give us a full 10 inch wheel. -> We are working on sourcing a controller for the motors. An issue for us right now is finding a motor that has the right pin input for the 9-pin round output the motor comes with. -> Finalizing our order for the motors, go to Professor Furman to make sure we're making the right decision and that he knows what we're doing. Next Week: -> Do FEA on motor housing -> Do any final modifications/FEA on shaft -> Finalize CAD on both shaft and housing -> Find a controller, make sure controls team and Professor Furman OK it. -> Order controllers + motors
