Mars Exploration Mission

Ideation
1. Criteria
  1. Prescribed
    1. Go around immovable objects
      1. Touch sensor has to be pushed in very deep before it activates
        Immovable object would activate
        If only ultrasonic is activated, it's movable
        Movable would not
        Move movable objects
    2. Move movable objects
      1. Ultrasonic sensors detect all (if large enough) objects
        Both immovable AND movable would activate
        If touch and ultrasonic both activated, it's immovable object
        If only ultrasonic is activated, it's movable
        Go around immovable objects
    3. Follow line
      1. Could use this existing algorithm:
  2. Self-determined
    1. Externally display if robot gone off course
      1. Use screen of EV3 brick to display faces
    2. Perform celebration dance once course if completed
      1. End of course is red
        Can use following algorithm to detect end of course
