EV3 Problem

EV3 Problem

1. Sensors

   • colour sensor
     • The colour sensor can be used to direst colours and help the robot line follow
       • Has different modes
         • Colour sensing mode
         • Reflect mode
         • Ambient mode
   • Ultrasonic
     • The ultrasonic sensor can tell the robot the distance between it and the nearest object in front of it
       • can tell the robot if there is an obstical or wall in front of it
       • Can measure in metres or inches
   • Touch
     • The touch sensor can help the robot identify whether an object is moveable or immovable
       • The distance the sensor is from the body can vary the decision made by the robot

2. Prescribed Criteria

   • PCT - Follow The Line
     • Requirments
       • Can navigate intersections
       • Robot can turn right
       • Robot can turn left
   • Detect and navigate around immovable objects
     • Requirements
       • Can use sensors to detect whether an object is moveable or immovable
       • Robot can navigate around immovable objects
       • Robot can return to and continue path
   • Detect and clear the moveable objects from the path
     • Requirements
       • Robot can define whether of not an object in movable
       • Robot can successfully move a moveable object from the path
       • Robot can return to and continue path

3. Self Determined Criteria

   • Victory Dance after completing tasks
     • Requirements
       • Robot can successfully display light
       • Robot can successfully display sound
       • Robot understands when tasks have been completed

4. Constraints

   • The Map
     • The Map cannot be changed/ edited
       • the line path the robot must follow cannot be changed/ edited
     • Objects on the map cannot be changed or removed
       • objects are part of the prescribed criteria
       • Placement of objects also cannot be edited
   • The EV3 Robot
     • Robot sensors cannot be changed
       • All sensors must be used during program
       • extra sensors cannot be added
         • limited use of sensors. e.g. two light sensors instead of one would allow for better line following
     • The Robot design cannot be edited
       • parts cannot be moved or added
       • parts on the robot cannot be removed
