WEEK 9/21 - 9/28 Progress

First wave of Presentation 1 This week we focus on preparing our presentation.

Preparing for the Design Review

The team's main focus, like many of the other teams, this week is to prepare for the Design Review/Presentation. Most of the time this week was spent preparing the presentation as well as prepping the project for presentation.

Possible Designs for Improvement

Figure1: Current Bogie Design

The principal issue of the current design of the bogie is the switching mechanism. The current bogie utilizes piano wire to connect the servo to the switch side mechanisms. Though piano wire can be effective at times, it's lifespan is very short. A more robust version of the switching mechanism is needed in order to make the current design effective. The new design should be have a sturdy connection between the servo and the switch mechanism. It should also easily accessible for maintenance.

The improved connection that is being proposed is to design and 3D print a custom servo horn that would ball joint ends. The connection would then be a link that contains a ball socket on one end. The socket will have to be designed in a way that allows the connection to move in all the positions it needs to be able to.

Another proposed solution would be to keep the basic servo horn and design and 3D print the connector alone. This will be replacing the piano wire. The connection link will be designed in a way that it can be easily attached and taken off of servo and switch

Progress for Week 9/7 - 9-14

For this week we continued our research on the bogie structure from the past year reports. We started to think about the different kinds of materials we will use for the different prototypes. We also made a  team roster and shared the information with all the teams for the 1/12 scale to communicate with each other to start working together. The next step is figuring out when we could have a general meeting. It was also discussed with the other team members that is essential that each sub team have a group leader to make the communication easier with the teams. We also extended our Gantt chart to date of the Paseo Public Prototyping Festival.

Proposal Narrative

This team's goal is to make as much improvement on last year's design while also saving more money than last years design. 

Requirements 

The 1/12th scale model will have a more futuristic design that will not exceed the cost of $300, from the previous design. 

Deliverables
