== Programming Assignment == For this assignment you will write a program that controls a set of rovers and sends them commands to navigate on the Martian surface where they take samples. Each rover performs several missions and each mission follows the same sequence: deploy, perform one or more moves and scans, then return to base and report the results. While on a mission each rover needs to remember the scan results, in the same order as they were taken,...
