 * You MUST use the pheromones to navigate your robot to the food source and back to the colony. Use of map probing or other god-like techniques will result in grade deduction. Remember, you are programming like you are the ant. Be like ant, my friend.

 Once a robot encounters a virtual wall, it will begin its journey home leaving a pheromone trail in the virtual environment.  Leaving a virtual pheromone in the environment is accomplished by sending a location to the Environment Java Class.
-Other robots will determine if there is a pheromone trail by querying the map with its current location. The pheromones will return values based on the last time you have visited the current location. For example, a pheromone on space X will return 999 if you have left a pheromone there 10 minutes ago while a pheromone will return 10 if you had just recently visited that location.

 The map is also able to print the current state of the world in an XPM format.  The pheromone trail is color coded where red spaces is where the robot has traveled most recently and blue is least recently.  The following method will allow you to draw the map:

 When the robot has navigated back to the colony, it must again follow a pheromone back to the food (can you figure out which ones?) and return back to the colony.

-The robot begin by executing a search for food.  This is done by random movements until 1) food is found, or 2) a virtual pheromone is encountered.  At each discrete location, the robot will leave a virtual pheromone in the virtual map.  If food is found, return home while leaving a trail every 15cm.  If a pheromone is found, then follow the pheromone trail until it can't find any more pheromones, or until it finds food.

+The robot will begin by searching for food. This will be done via some sort of searching algorithm. As the robot moves, it will leave pheromones at each spot it has visited. To model decay, these pheromones keep track of the elapsed time since since you left the pheromone.
 ==Food==
 Virtual walls are what our ants will use as food.  When our Create encounters a virtual wall, it will "pick up food", then return home by following it's original pheromone trail while leaving pheromones for the other robots to find.  They will be positioned from above with the IR beam pointing downward to simulate the effect of a food source.  There will be two virtual walls, symbolizing two food sources.
