Hephaestus is a rocketry payload made by Oregon State University for the RockSat-X program. The faculty advisor for this project is Nancy Squires. The involvement of twelve of the project contributors is part of the Senior Design classes. The Senior Design groups include two Mechanical Engineering groups, an Electrical Engineering group, and the Computer Science group. This repository is for project deliverables for the CS Senior Design class as well as any design documents, code, testing, data, and documentation generated by the Computer Science team throughout the 2016/2017 Senior Design year.
Participation and flight in the RockSat-X program is subject to revue and approval from the Colorado Space Grant Consortium. Pending this approval, the Hephaestus payload will fly in August of 2017.
The Oregon State University RockSat-X team will demonstrate that an autonomous robotic arm can locate predetermined targets around the payload under microgravity conditions by using precise movements. The technical actions performed by this demonstration will illustrate a proof of concept for creating assemblies, autonomous repairs, and performing experiments in space.
This section will describe the contents and structure of this repository.
The deliverables directory shall contain all deliverables for the CS Senior Design course. These deliverables are broken up into the term and assignment subdirectories. Assignments will be added through June 2017, at which point the course will conclude.
The Design Documents directory contains all design documents that we create. These shall be further organized by term and subject, pending need for organization. For the moment this shall be a place for any in progress, partial, or draft items.
The Photos directory shall include all photo documentation for the project, including any graphics for promotional use (such as logos or flyers).
The Presentations directory shall include all presentations given by the CS team. This will include all presentations for RockSat-X program design reviews, presentations for promotional purposes, or for fundraising purposes.

Before you can build the code for this project, make sure you have the avr-gcc compiler as well as an ATmega128 microchip and programmer. You can obtain a copy of the avr-gcc compiler from the WinAVR suite for Windows, or by installing the avr-libc, binutils-avr, gcc-avr, and avrdude packages from your Linux OS's package repository. In the case of OS X/macOS, ensure that you have version 5.11.1 of avrdude installed as the most recent version does not work with our implementation. The ATmega128 chip can be purchased from Microchip's website here. Also, be sure to have a programming board for your ATmega128 chip, which can be obtained from the OSU TekBot store.
