This Friday we have our final presentation, and some small adjustments to the motor. For cable management, we 3D printed a small fender for our motors' wires to fit through. Our presentation is linked below.
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)
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...
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
