Week 04: Design Technologies and Materials

Class Task and Information

  • Lesson 01:
      • Review of the first 3 Weeks.
      • What is our road map forward?
      • Working with Colour sensor

    • Task 01:
      • Course Check Point so far - Answer the following question (Click here for the Google Form)

        • From your knowledge at the start of week 1 lesson 1 to where you are today, week 4, How much do you you think you have learnt on the following topics
            • From ---- Very Little ------- to ----- Lots more than I expected
            • Building With Lego
            • Coding in general
            • Coding movement
            • Solving problems

        • What aspect or aspects of the course did you find very interesting?
        • Is there any part of the course you think should be removed so far? Why?
        • What is something you think we should have looked at? Why?
        • How did you find the delivery of the course so far?
        • Do you have and general comments or improvements?

    • Using the Colour Sensor
      The Colour Sensor can be used in 2 different modes to solve this challenge (i.e., Colour Mode or Reflected Light Intensity Mode).

      The Colour Sensor’s Reflected Light Intensity Mode will give maximum precision. Following a line is an alternating detection of 2 colours or 2 reflected light intensities.

    • Programming task #1 - EV3 Jukebox
      • Have your robot play different sound when you present it a different colour (Use 3 Colours)

    • Programming task #2 - Put the breaks on!!
      • Have your robot travel at 50% of its speed until it sees a colour and then reduce it's speed to 20% then stop.

    • Extension task:
      • Using the variable, reduce the speed by increments so the speed reduces by 5's or 2's etc

      • Remember: to record your success and place a copy of your code in SWT

  • Lesson 02:
      • Working with Colour sensor

    • Task 01:
      • Hardcoding the exact movements that a robot must make isn’t very efficient. Therefore, robots have different guiding systems to help them navigate their environment. One simple yet effective option is to use coloured lines on the floor, which a robot can follow using a sensor.

      • Answer the following questions in your design journals:
        • Do you know of any robots that can detect colours?
        • What are the advantages and limitations of using coloured lines as a means of navigation?
        • What’s reflected light intensity, and how does a Colour Sensor work?

    • Programming task - Following the line
      • Can you program your robot to navigate around the square using the light sensor.

      • Remember: to record your success and place a copy of your code in SWT
