Throughout this week, we continue to work and build our final project. Most of the parts have been welded in place to ensure that we began to test and fix any problems. We were able to take the current bogie that we have and place it on the tracks to see any problems that may have arise. Some parts were not welded on until we tested the bogie on the rails to accurately place them in the correct spot. One thing of noticed is the since of the wheels, We might need to gather bigger guiding wheels to ensure that the bogie is sits straight and not at an angle. Also, the last parts have arrived thus we will be implementing the steering system soon enough. Overall, we are in the testing and finalizing the building stage. The other teams are dependent of us thus we want to finish as soon as possible for them to work around our bogie. We took our current bogie to the shop in order for the rest of the groups to see where they will fit and how their projects will assemble with our own. Overall, we are making good progress.

Throughout this time, the construction of the bogie has been the priority. We have been working at TechShop to finish our project as soon as possible as other teams depend on our work to get their own work done in time. We also want to have a reasonable period of time in order for us to test and resolve any flaws that we may not have yet located. Also, the final parts have been order and should be here some time soon. The gears, pulleys and timing belts are the only parts that we will not be making ourselves. Overall we should be done with proper time to test the bogie and also give the other teams time to test their own parts on our system.

Winter Break - 2/8

Lots of parts have been machined already including all sheet metal parts, most of the gearbox housing, rod ends, and square tubing, and we are getting ready to put welding the main structure together. The parts that still need to be ordered include the gears, fasteners, pulleys, and pulley belts. We will be ordering them within the next few weeks. We will continue manufacturing parts, and will beginning welding everything up soon.

Presentation 3


For the last two weeks, we've been working on getting together the BOM for all parts that will need to be purchased for the Spring semester, working on the 3rd presentation, and working on the rough draft of the final report that is due at the end of this week. There are still some details that need to be worked out. Engineering drawings for all of the parts that are going into the bogie need to be made for the final report and for manufacturing that will occur next semester. Michael has started working on these, however, it will take some time because there are so many different parts going into the bogie design. The goal for this week is to finish the rough draft of the final report in order to get feedback for the final draft which is due coming up.

During this week, we continue our progress in our Bogie, Failsafe and Steering. All subsystems are coming together little by little. In the current CAD design, the propulsion, breaking and suspension sub-systems have been implemented. The design has not been finalize but it will be a preview to visualize the final design. There has been minor changes in our design as we have noticed some issues. For example, the angles of our steering changed slightly thus one of the pulleys changed from 24 teeth to 28 teeth. The linkage controlling the upper steering instilled us to make the change. Also, some gaps in the bogie were changed in order to mount the gear housing system. Also, we began to write the rough draft for our final report. Adding all details of our design and explaining why the changes took place will be of upmost importance to ensure that future teams are able to improve and progress.  Also, we will be finalizing the B.O.M. for our parts. We have yet to turn in the B.O.M as we want to completely finalize our design and obtain a accurate total cost to ensure fundings are delivered as necessary.

During this week, our group the main focus to finalize is the housing of the gears, the prototype testing and the implementation of the subsystems. The function housing of the gears is to keep in place the gear system without impeding any functionality of the rest of the subsystems. Essentially, the limited space in-between is the main concern for this design. The rapid prototype is made of wood which will enable us to observe the functionality of our current design. The main functionality of our prototype is to identify exactly the tolerances necessary for the Bogie to stay in place as it goes up and down the slope. The tolerances of the two bottom wheels are of upmost importance as it will prevent the bogie from hitting the top. Testing our current design is necessary to change any details as soon as possible to avoid late major changes in the future. By allowing ourselves a respectable amount of time to finish our design, all unexpected errors can be resolved in a timely manner. Also, in accordance to the groups, the date(November 16) we planned to order parts is approaching thus all the parts necessary for our system will be listed to meet the deadline. The implementation of all subsystems is of upmost importance as all systems will come together in the end. We have been keeping close communication with the other teams as well as sharing all our design CAD files to ensure that their design will fit accordingly.
