  1. Lesson 2 Inputs

  2. Lesson objectives • To understand how inputs can be used to control an output • To consider how to make mimics more realistic

  3. Inputs • Most forms of control technology respond to some kind of input. • Inputs may include • a button • a switch • a sensor

  4. Flowol Robot • Open Flowol and go to the Robot Mimic. This robot has 4 inputs across its chest. These are different shaped buttons It has 4 outputs. An antenna, mouth and 2 eyes.

  5. What does this shape do?

  6. What does this flow chart do? Try and create this for yourself. When the square is pressed the antenna should go up, wait a bit, then go down again.

  7. Task 1: • Create 4 flow charts to control the following • Save your flow charts as ROBOT1

  8. We want to mimic real life control events using flowol. Pretend that the robot is a real life toy • How can we make the robot buttons control the outputs in a more realistic way? • Example • Would you use separate buttons to control the eyes? • Would it be better to press a button to make the antenna go up, then press another button to make it go down? • What else could we change?

  9. Task 2: • Change your flow diagrams to make the buttons have more realistic responses. • It is up to you how to choose to change them, but you must be able to justify why you have made your decisions.

  10. Task 3: In Pairs • Explain your changes to the person next to you. Let them test your flow charts to check they work. You must explain • The change you have made • Why you think it improves the robot • Swap and test your partners flow charts.

  11. Share with the class • What changes have you made? • Why do you think this improves the robot toy?

  12. Extension • Open the School Bus mimic. This mimic has 6 inputs (the buttons on the dashboard) And 9 outputs

  13. Extension Task • Program the 6 buttons to do the following.
