Week 05/01 - 05/08

Week 13 was when my team and I started assembling the parts together, including drill-pressing the metal sheet on the drive bogie. We met at the Central Shop along with the bogie interaction team to see the progress of the drive bogie's metal sheets. After reaching out a conclusion of using collar shafts and screws to hold the shaft from unthreading itself, we have to drill several holes on the drive bogie's metal sheets to be able to implement our ideas. Hence, we met at Central Shop to start working on drilling the metal sheets. We measured out the dimensions and we started drilling. The dimensions that we went was exactly an inch, hence, we had to file some of the holes to make sure that the shaft fits through it. After filing, we tested and our shaft went through. The next thing that we are going to test is the screws on the drive bogie, collar shafts on the drive bogie, and the motor running on track.

Week 04/24 - 05/01

Week 12 was when we received our parts from the Central Shop. As of now, we have 4 motor casings and 1 shaft that will hold both axles of the motor on the drive bogie. During the weak, I met with my teammates to see whether the casings and the shaft will fit the motor and to check whether there are any problems that we might encounter after assembling the motor case and shaft. Everything fits fine, however, we are worried that there might be torques applying to the motor case when it moves during the demonstration, resulting in the motor's axle to unthread itself from the shaft. If this actually happens during Makers Faire, there are possibilities that the motor will fly out from the shaft. Hence, we talked to Dr. Furman and came up with the conclusion of using a collar shaft on each of the shafts ends to lock the shaft from moving. Also, we will be adding two screws to the drive bogie so that the motor can absorb the torque exerted by the friction and keep the shaft from unthreading itself.
