Proposal Narrative
This year there are a few things that I want to get accomplished with the small scale track. Below are a each of the sub team division and the goals I have for those teams.
For the track group, I would like them to work with the small scale solar and power team to design a modular track system which can be laid out into a grid. Each component such as turns, stations, forks, and straight aways would be design with a standard unit length such that components can be easily swapped out without modifications. This would make the track virtually infinitely expandable as long as we have materials and space. This would also make modeling the track in our controls system more easily due to the grid modular design. It would essentially be similar to a “train simulator game” where tracks are laid down in units.
For the controls group, I would like them to start doing object oriented programming for the carts. This can be easily done by programming in Java or C++ and programming then using classes or objects. Currently we have a problem with positioning but if we use a grid modular design we can estimate a carts location within each cell rather than getting its exact location. Collision avoidance could also be done by foreseeing which there the cart will be next and letting the one who's going straight, or going faster go first. This can be done by reducing the speed of the cart going second. Furthermore, as another safety precaution, the proximity sensors will sense if the carts are in close proximately with one another and will reduce the speed accordingly. The controls team will also be responsible for designing the carts circuitry and programming which most likely will use the original Arduino board, however a wifi chip may be needed instead to use a WiFi router as the communication system since for its speed and ability to communicate to multiple devices, this can be done by creating a server and client system using web based applications. Lastly if we we could create a reliable local positioning system, we could use it to represent our real life GPS positioning system so our control system would be more applicable in the real world. Not only that, based on our research for a local positioning system, if we are successful with that, we would also be rich, since that's the next big thing.
Finally for the cart and pod team, I would like them to redesign bogey slightly so it uses the same arm mechanism that is on the intermediate cart rather than the shifting wheels. The other goal for the cart team is to also produce at least three carts for this project for demonstration purposes, and if we have the resources perhaps up to 10 if we have the resources and the controls system up and running.
There is a lot of work to do for this project and with a team of 9, we have a lot on our plates. This is mostly what we plan to do, and as you can see there aren’t as many task for the track/rail and cart/pods group, this is because I plan on completing those tasks early so we can seriously develop the controls system for this project. Once completed it can then be implemented on the intermediate scale project whenever it is ready for it in the future. I would also like to note that these are the goals, however I, and everyone in the group, would like to work on different parts of the projects. This will help with integration of the different parts of the project while still maintaining groups with a focus in their sub-division.
Deliverables
By the end of this project our we would like to deliver a working model of the small scale system with multiple carts and a functioning control system. If really successful we would also be able to deliver a reliable local positioning system and a plausible control system that could be applicable on an intermediate scale system.

Schedule
Currently we are in the design phase, we will mainly be redesigning the carts to have a bogey that more closely resembles the intermediate scales bogey. At the same time we would also be planning out the track design, since we already have a station designed and fabricated from the previous year we may base our unit length on that station and build upon it to avoid spending unnecessary time on the designing just the track. Since our main goal is the control system for this project we would start planning out our software are programming early. We would generally spend part of the first semester understanding the old code when we get the source code and start programming as soon as possible. The second semester will be used to fabricate the actual model and then implementing all the systems together and fine tuning until its silky smooth.
Budget
We do not yet know the budget for this raw material since there is material that has already been bought by last years year’s small scale team however we would need money to buy several Arduinos and their WiFi boards, motors, speed controllers, and a computer to be used as a server.
