Mars Exploration

1. Resources

   • EV3 robot
     • Motors/Actuators
       • Rotates/turn wheels
         • Allows robot to travel around the map and navigate around immovable objects
       • Robot arm
         • Used to move movable object
         • Can be raised or lowered
     • Sensors
       • Ultrasonic
         • Distance in cm
       • Touch
         • States
           • Pressed
             • 1
               • detects immovable object and navigates around it
           • Depressed
             • 0
               • Continues running the program
       • Light
         • can sense different colors
           • Allows robot to act according to colour
             • Red makes robot stop (SPC2)
             • Green tells the robot to turn (SPC1)
             • Black and white helps the robot stay on track
   • Online
     • One note
     • eLearn
     • Microsoft teams

2. Non-functional Requirments

   • Legal
   • Makes it back without failing, due to enviroment

3. Functional Requirements

   • Prescribed Criteria
     • Follow the path
       • This can be done by using the light sensor to sense black and white line
         • Then, a code could be created
           • • Mars Exploration
     • Detect and navigate around immovable objects
     • Detect and clear moveable objects from path
       • The object could detected using this code along with the touch sensor
         • • After detecting, this code will help move the object away
   • Self-determined Criteria
     • Must choose the fastest route
       • To avoid unexpected errors
         • e.g. runs out of battery, bad weather
     • Arrive at the detsination and stop
       • The robot could detect something using the 3 sensors
         • Touch sensor?
         • Light Sensor?
         • Ultra sonic sensor?

4. Constraints

   • Personal
     • Lacking of coding skills
   • Time-limit
     • 4-weeks
   • EV3
     • Sensors
       • Touch
         • Only in front of the robot
         • Has to be compeletly pushed in
       • Light
         • Could be unreliable due to lighting in room
       • Ultra sonic sensors
         • Can only detect thing in front of it
   • Map
     • Can be dirty
       • Disrupts light sensor
