The power budget outlined below in the following table details the estimated electrical requirements for all major components of the Astraeus rover, including both control and electro-mechanical subsystems. It accounts for voltage, current, and total power consumption of each module based on expected operating conditions. This breakdown was essential for selecting an appropriate battery system and designing a reliable power distribution network capable of supporting sustained autonomous operation. The power budget ensures that all onboard systems function efficiently without overloading the rover’s power infrastructure.
