This week, our team gave our final presentation which can be found below. We are happy with how the bogie currently functions and will be producing more bogies to allow the controls team demonstrate their project.

Our team collaborated with the controls team to test the function of our final bogie prototype. With the arm in the correct switching position as shown in the image below, the bogie was able to perfectly execute a track switch. The bogie traveled faster than expected with the new battery ordered by the controls team. Our team will now create two more replica bogies as we prepare for our final presentation.
This week, our team finished assembling our final bogie prototype. We were able to mount the bogie on a switching section. The bogie was able to fully support itself with the arm on the master system when placed over the gap within the switching section as shown in the image below. The bogie should operate smoothly when we test the bogie's overall functionality next week.
Our team focused on 3D printing the bumpers for the bogie as shown in the image below. The original bearing distance was too narrow which was causing the bogie to wander around on the track in excess. The newly 3D printed bumpers will keep the bogie centered which will help save energy and create a smoother operation of the bogie system.
This week, our team gave our second presentation for the semester. We are on track for creating three functioning bogies. We hope to test our newly built bogie on the track turning section within the next coming weeks. Our presentation can be found below.
Although our new master system is functioning flawlessly, the bogie is still binding during the turning section. To remedy this, our group created a set of chamfers that ran along the length of the bogie. This will elevate the bogie which will keep it from rubbing on the track during a turning section. An image of the chamfer design can be seen below.
This week, our group focused on creating a working model of our new master system prototype this week. An image of our newly 3D printed and assembled master system can be found below. This system spun both wheels in an efficient manner without causing any binding. The previous design could not be spun by hand due to binding which proves that this new straight-cut gear design is superior.
