2. We programmed the squirrel to perform a number of different behaviors. Our main goal was to have the robot emulate the behavioral patterns exhibited by an actual squirrel. Its actions had to appear as if determined by self- preservation instincts. The robot had to not only search for sources of food but also had to maintain a constant vigilance for predators. The squirrel first and foremost looks for the predator. The squirrel utilizes an ultrasonic sensor to determine the location of the predator. If the predator is closer than ten inches from the squirrel, the squirrel would scream and immediately seek a tree. If the coast is clear, the squirrel would seek out food using a light sensor.

3. The squirrel is programmed to run over the white background until it finds a variance in color. It seeks to find more food-reacting with a happy sound and smiley face once it finds a certain number. If the squirrel finds a tree before this quota is filled, the number of food items returns to 0, as if the squirrel had stored the food in the tree. If this number is not met within a given time frame, the squirrel will appear sad, as is signified by a unhappy sound. This all occurs while the squirrel continues is watch for a predator. If a predator is sensed at any time by the ultrasonic device, the food-seeking behavior is abandoned in favor of a fleeing behavior. The Sensors Light: This sensor emits a light. The squirrel reacts depending on how the light is reflected back into the apparatus. A higher intensity signifies a lighter color and the inverse also holds true. The white background of our map read at an intensity of 55 or greater, the light gray food source was between 55 and 40, the gray trees were between 40 and 20 and the black border registered at approximately 20. Ultrasonic: This sensor sends out a sound wave. the distance an object is away is found depending on the time it takes for the wave to return to the sensor. The less time the return wave takes, the closer an object is to the sensor.
