Objectives:

  • Demonstrate "Gracious Professionalism" in working as part of a team
  • Analyze a robot as a system
  • Build the "Hungry Alligator" using WeDo components.
  • Program the "Hungry Alligator" using WeDo programming language
    • Incorporate a motion sensor as an input device
    • Modify the program to use the keyboard to control the alligator and/or change how the alligator chews his food
  • Understand how the Hungry Alligator's program is similar to and different from a real alligator brain.

In-class extension:

  • Design an appropriate habitat for your alligator. Take a picture or video for the class wiki photo gallery.

Use the instructions from the WeDo Activity Pack to build the Hungry Alligator.
Create a program that will tell the alligator to chew his food when it is in his mouth.





Other Extension Activities:

You might want to try one of these extension activities (optional):

1. Modify the program to make your alligator chew his food a random number of times when the sensor is triggered or modify the program to make your alligator chew his food on command.

2. Find out where real alligators live. What are their habitats like? Draw a picture or write a short story about it.

3. Find out about people who design robots. Read or watch one of their stores on the roboticists page. Do you think you might like to be a roboticist? Why or why not?





4. Learn about how robot designers try to make their robot's programs more "brain-like". Watch this example of soccer playing robots. Are the robots better players than most children? Why or why not?
