Cup stacking Activity
Launch the activity by discussing robotics. To program a robotic arm we need to give a robot very specific instructions in a language the robot can understand.
Use Student Handout as students follow through the activity.
Close-Out (5 minutes)
What are procedures? Sequence of instructions that can be called on to do a certain task, eg Chorus, eg Dip and Roll, eg. MoveArm4
Why are they useful? Code is shorter. Code is more readable.
