Abstract:

Our team is designing and developing a Mars rover concept. The rover’s purpose is to navigate the rough terrain of Mars and conduct an off-world mining mission. By utilizing sensors, the rover will collect regolith samples and conduct in-situ analysis for life. The Mars rover will navigate on an ABS rocker bogie design with 6 wheels. Motors will be independently controlled using an Arduino motor controller (L298N) to allow for steering. Through a coded controller, the rover will navigate with a 5.8GHz wireless camera, using a scooper mechanism to collect soil by servo motors. Powered by 2P 5V solar panels and 3S3P 12.4V Li-ion battery pack, the rover’s BMS (battery management system) will regulate the Li-ion battery during load and charge times. Connected to the battery is a 12V->5V step down module to test samples in the payload. Sensors will examine for extant life, extinct life, and the presence of water. A methane sensor will test the regolith, as methane is a possible indicator for life. Sensors for soil moisture and temp/humidity will look for water and ice polar caps to collect additional samples in search of microbes.
