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 that will house the motor and become our wheel.

-> For our new shaft design, we are designing a threaded axle that will connect one motor on each side of that shaft. This is done to help distribute the weight throughout the axle, rather than having all the weight sit on two sheets of metal from bogie interaction design. We will be meeting with them on Wednesday to discuss further.

Upcoming Week:

-> Deliver KBL controller to controls team.

-> Continue CAD designs

-> Look into rapid prototyping

-> Run FEA analysis

-> Look into what material our shaft and case would be.

-> Find a machine shop that will cut our design in the future and get expert recommendations.

    Full Scale Motor Team,

    I am looking forward to seeing some of your designs, and finally some testing results on your motors and controllers.
    PLEASE be sure to read the motor / controller instructions carefully. Last year, we had a team buy a motor and controller, and hardly follow the directions which resulted in failure.

    Lots of work to be done, keep it up

Week 9: 10/17 - 10/24

This week: -> Got together as a team to work on presentation -> Also meet up with other teams to make sure that all information is up-to-date and the same. -> We are currently in contact with XOFO motors about a recommended motor, since MAC Motor has been unresponsive. -> Ran kinematic simulations on the motor XOFO recommended. -> Calculated outputs of our motor to make sure we have enough output to move bogie Since we have decided to go with another motor: -> Drew preliminary CAD drawings our shaft -> Ran FEA on our designed shaft -> Got an invoice for 6 motors without controller -> Updated Gnatt chart: motors are currently delayed but on schedule for everything else. -> Spoke with Dr. Furman about reducing the number of motors needed in order to save money Next Week: -> Continue CAD design of shaft and motor casing -> Keep in contact with XOFO, MAC Motor, QS, and TDCM about motor -> Purchase Motors (4)

2nd Semester Week 13: 5/1-5/8

The main focus this week for the motor team was to work with bogie interaction team to integrate the motors, motor's wheels, and axle onto the drive bogie. During this integration process, both teams ran into quite a bit of an issue with manufacturing the hole on the drive bogie for the axle to be fitted into. It was originally planned so that hole sizes of approximately 1.010 inches were to be water jet cut into the four supporting plates of the drive bogie; however, bogie interaction team wasn't able to have those holes made during the water jet process. This means that we had to use a drill press to create the 1-inch holes. The problem with drilling the one-inch holes manually is that it would be quite difficult to have all four holes on the four plates to align properly for the axle to slide through. To resolve the issue, we filed and milled out the holes to a greater size for the axle to be fitted into. To further secure the axle, we incorporated face mounted lock colla...

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
