To begin, open and examine spec/command.spec.js. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? It also contains a function, receiveMessage that handles the various types of commands it receives and updates the rover's properties. After writing the parts of the rover on the board, have students describe the function of each part of the rover. One of the more challenging aspects of developing flight software (FSW) for NASA's Spirit and Opportunity Mars Exploration Rovers (MER) and Curiosity, the Mars Science Laboratory rover was how to enable them to drive themselves safely through unknown Martian terrain. Each rover has two lines of input. Assume that the square directly North from (x, y) is (x, y+1). The first line gives the rover's position, and the second line is a series of instructions telling the rover how to explore the plateau. value is a value related to the type of command. How to tell which packages are held back due to phased updates. When driving Mars rovers, we have to be very intentional about how we move a rover across the harsh landscape to reach its destination.
