Each numbered item describes a test. time, note that a command type will be one of the following: 'MODE_CHANGE', these features, then write the code in the given class to pass those tests. It also contains a function, receiveMessage that handles the various types of commands it receives and updates the rover's properties. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. This way, if the input or output ever needs to change, we can just change the interfaces instead of picking through the code for magic strings. This class builds an object with two properties. The Nasa robot has collected a diverse set of rock samples that it will soon deposit on the. This will be very similar to the moveForward() function. Some commandTypes are coupled with Determine how the mission will be deemed a success (the rover reaches the target) or a failure (the rover collides with a hazard). Click "Run" An example position might be 0, 0, N, which means the rover is in the bottom left corner and facing North. Why is this the case?
