Environment Perception Hardware

[kchevali]

This is a possible solution to handle different stimuli in the environment. The stimuli could be food, enemy, home, queen, water or more. Each stimuli would need all or a subset of the following hardware components:

Hardware

• CPU flag: turns on when the stimuli is within a certain distance.
• Read only register: reports the distance to the closest instance of the stimuli within their perception range.
• Instruction that takes 1 step along the shortest path to the closest food.
• Instruction that runs away from the stimuli, possibly a step towards the furthest position from the stimuli that the ant can perceive.
