The table below key components used on Astraeus, along with the engineering specifications and reasoning behind each selection. it is important to note that every part was chosen based on performance requirements, such as torque, current rating, and durability, while also considering cost, availability, and ease of integration. This approach ensured that the system remained within a realistic scope for a senior design project. Each selection supports the overall goals of functionality, modularity, and long-term reliability in a Martian-like environment.
