Week 1-9_2/6-4/10/19
Week 1 | 2/6/19
This week was mostly spent moving everything from the old location to the new Superway location. When organizing our materials and tools, we found a printer, monitor, and a mini PC. I was able to get it up and running after trying out a few of the printers that were already in the new building. Next week I will take a few minutes to make sure the software (Solidworks, OS, Microsoft Office) is up to date.
Week 2 | 2/13/19
This week there was a guest speaker talking about work done on other transit systems like BART. After this presentation, we were able to start gathering our things to figure out what needed to be done next. I was tasked with shortening the steering chain. To prevent unnecessary damage to the chain, I ordered a chain breaker tool to shorten the chain properly.
Week 3 | 2/20/19
This week was mostly spent measuring the track to find the dimensions required for MakerFaire. The track will need to be shortened to about 18' long and 4' tall. This means the bogie will not be traversing the track as originally planned. It will need to go back and forth and stop at each of the three endpoints. Originally, it was only going to stop and change direction at the two endpoints. The new setup still allows us to demonstrate the same functionality and automation so it is not a problem.
Week 4 | 2/27/19
I was able to get the printer to work with the mini PC we found on week 1. We used this to print things for our team poster board. The chain breaker tool arrived, so we can get to work on shortening the chains. We used the last half of class to tidy up the place and organize things. We will begin preparing for the presentation next week.
Week 5 | 3/6/19
We had presentations this week, but ran out of time for our team. Our team narrowed down the tasks for each member. My task was to get the shafts machined for the steering arms and gearbox. MakerSpace seemed to be the best option, so I got in contact with them to get that done.
Week 6 | 3/13/19
Our group presented this week. We got the shafts back from MakerSpace, which was one of the main things hindering progress on the mechanical side of things. I also helped out with some of the Arduino coding for the velocity reading.
Week 7 | 3/20/19
I was able to use the chain breaker to shorten the chain to the required length. There was a kink in the chain that would sort of catch on the gears and the chain had a bit of slack. The slack did not seem like it would present too much of an issue. The kink needed to be fixed before testing could be done.
Week 8 | 3/27/19
The second chain came in, so I shortened it to the same length as the first. I was able to fix the kink in the chain and made sure the second chain would not have the same problem. The slack did not seem like it would be an issue, but we still needed to have a backup plan if it became a problem. I found some already made chain tension fixtures on McMaster, but we could also design our own if necessary. We do not have the shafts or gears for the second bogie yet, so this was just to save time later.
Week 9 | 4/10/19
There were presentations this week, but the last half of class was used for moving the rest of the tracks from campus to Superway. We had gotten limit switch holders 3-D printed, but there were some small pieces from the printing process that needed to be removed. I was able to get this done today along with working on completing the presentation for next week.
