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.
The motor casings and the new shaft came in. We tested the controls with the casings on one motor with the shaft attached and it was able to move just fine. However, we're worried that the torque caused by the friction between the wheel and the ground will cause the shaft to loosen up and unscrew itself from the motor. We talked to Professor Furman, and we came to the conclusion that adding two screws to the bogie on either end of a lock washer that came with the motor will be enough to absorb the torque and keep the shaft from unthreading.
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)
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
