Robotic ants foraging for food

Overview

The goal of this assignment is to get our iRobot Creates to use teamwork to find and bring food back to our home colony. In this case, our robots will simulate ants in following a virtual pheromone trail set by ants that have already found food. The food in this instance would be the IR beam emitted from a Roomba virtual wall and detected by the IR sensor on top of the iRobot Create.

Goal

Using only the simple behaviors, drive, read pheromone, pick up food, leave pheromone, we want to find enough food to get us through the winter.

Details

• Each student is responsible for developing the specific simple behaviors which (we hope) will produce the desired emergent behavior.
• We will provide Java skeleton code as a framework for build the specific behaviors.

Behaviors

The following behaviors are required:

• "Find Food" - implement a basic behavior to find food and update it's position on the virtual map, and maintain its position and/or the path it is taking in memory (so it can find its way home).
• "Return Home" - will set virtual "pheromones" on it's return to home base
• lay down virtual pheromone - this will send a message to the virtual map
• avoid obstacles (the other robots)

Map

Since the Create is limited in its computing abilities, each robot will be controlled via a laptop computer communicating over Bluetooth. The laptops will then send their positional updates to a central "virtual" map on a central computer. We will use this virtual map as our environment from which the robots will send/receive virtual pheromones.
