Presentation Transcript

  1. Session 3 Sensors

  2. Session 3 Aims: • To know what a sensor is (you might have introduced the Gyro Sensor in the last session) • Be able to use the EV3 Model to detect lines using a sensor • Be able to use a sensor to control action • Understand how speed can affect sensing on an EV3 Model

  3. What is a Sensor? • An input device that can detect or measure physical property • Can you think of any sensors that you have seen?

  4. We are going to talk a bit about theColour Sensor BUTYou can find more detail in the Help Section of the EV3 software When you are in the software – click on the Help Menu at the top of the screen and choose Show EV3 Help. In this case choose General - Colour

  5. The Colour (& Light) Sensor • Can detect up to 8 colours • Can also detect light intensities (light to dark) via the reflected red light emitted.

  6. How to program the EV3 to detect light The 2 panels you will need are: • Flow control (orange) – for sensors • Action (Green) – for movement

  7. The “Wait” Block Can select logic operators to compare measurements Can select the colour/intensity that you are looking for Can select which sensor you want to use

  8. Challenge - Following a line • Look carefully at the program here and explain what it will do. • What will be the impact on your EV3 Model? • Now, program your EV3 Model to follow the black line on the challenge mat.

  9. Real engineers Making film magic: If you’ve ever wondered how blockbusters get to look so good, it’s down to the work of people like Eugénie von Tunzelmann (picture to the right) who make ground-breaking visual effects. The film industry use a variety of sensors to create amazing effects in films like the Great Gatsby or Harry Potter. Serena is on a mission to prevent plastics from entering our rivers and oceans. Your robots will be doing water clean up challenges too! https://www.youtube.com/watch?v=1YDlvWnhh78

  10. Great work everyone! See you next time!
