Outline

1. [5 min] Angel for attendance. Questions?
2. [10 min] The Image object in Zellegraphics:
   • Constructing
   • Drawing and moving
   Module: m2_image_example.py
3. [20 min] Review: Robots using PyCreate:
   • Constructing a Create object (i.e., robot) connected to a port
   • Shutting down a robot
   • Moving a robot — straight, spinning or both at the same time — using the PyCreate go and stop methods, with a time.sleep function call in between
   Module: m1_robot_example.py
4. [10 min] Getting sensor input in PyCreate: the PyCreate getSensor method
   • Cliff sensor readings
   • Angle and Distance sensor readings
   • Other sensor readings
   Module: m1_robot_example.py
5. [5 min] Break
6. [10 min] Practice: integrating what we have learned so far
   • Loops, especially accumulator loops
   • Using objects: constructing and applying methods
   • Robotics: actuators and sensors
