'''MARS POLAR ROVER'''
'''MARS POLAR ROVER'''
The Mars Polar subteam is constructing an GPS-based autonomously-navigated rover to replicate driving conditions at the Martian polar ice caps in order to guide future NASA exploration of Mars. The long term goal is to test the rover on an expedition across Antarctica to reach the Earth's South Pole. Specifically, the rover will follow the charted South Pole Overland Traverse from coastal McMurdo Research Station to the Amundsen-Scott South Pole Station. The subteam has already built two small prototype lithium polymer battery-powered rovers with custom-designed snow tires and GPS navigational functionality via ArduPilot software. In the next stage of rover prototyping, we aim to incorporate solar panels, a Starlink installation for internet access for live control and video streaming, and a LiDAR module for object avoidance and path planning.
