Spider Challenge - The Finished Product

Activity Details:
Task: Choose an animal and study its movements. Create and program a robot to demonstrate the behaviour of an animal e.g. a tail wagging puppy or a jaw snapping crocodile
Start date of task: May 20th 
End date of task: July 24th

    • Sensors used: ultrasonic and light
    • Animal: Spider
    • He is called Kevin "Kev the Chev" Chevy
      • "Net-casting spiders have enormous, compound lenses that give a wide field of view and gather available light very efficiently. The lenses can concentrate available light more efficiently than a cat or an owl. Each night a large area of light sensitive membrane is manufactured within these eyes (and rapidly destroyed again at dawn)." - The LIGHT SENSOR on this robot is able to detect the amount of light in it's surroundings similarly to the way a spider is able too.
      • "However, most spiders that lurk on flowers, webs, and other fixed locations waiting for prey tend to have very poor eyesight; instead they possess an extreme sensitivity to vibrations, which aids in prey capture. Vibration sensitive spiders can sense vibrations from such various mediums as the water surface, the soil or their silk threads. Changes in the air pressure can also be detected in search of prey." - The ULTRASONIC SENSOR on the robot is able to pick up objects that are close by
