Lesson 4 Scribbler Writes
How do robots communicate? Can they learn to write?
The purpose of this lesson is to learn how to turn the robot at angles and move in arcs and circles, and spin around. You will also learn how Scribbler gets its name by inserting a pen and creating a drawing. By the end we will navigate a maze.
Time to Complete
- 1 hour for Hands-on Activities
- 2 hours for Optional Exercises
What We Will Learn
By the time you complete this activity you should be able to:
- Program the Scribbler Robot to spin around, turn in a circle, and rotate to angles
- Create drawings with Scribbler using a Pen in the pen port
- Use the Motor blocks to control Scribbler movement
- Navigate a maze by programming Scribbler actions
- Describe how the direction of wheels change to draw circles
- Describe how modifying the speed of each wheel effects how the robot moves
- Describe how to draw an S shape using the Scribbler
- Calculate the time needed for the Scribbler to draw different sizes of circles and arcs
- Develop a table that defines the time and speed needed to correspond to size of circles and arcs drawn
- Define and be able to measure the diameter, radius, and circumference of a circle
What You Need
- Scribbler Robot with battery charged
- USB cable to connect robot to computer
- Computer: PC or Mac to program the robot (with Internet connection)
- BlocklyPropClient software installed on Computer
- Paper to draw on and Pen which inserts into the Scribbler or white board and dry erase markers
What to Do
- Open the Worksheet document. The worksheet contains a checklist for you to check off items as you complete them, some questions to answer as you work through the activities, and optional Exercises.
- Watch the concept videos, and review the other items in the Start section. They provide background information which helps connect this lesson to other STEAM topics that you may be studying, and will help you answer the STEAM questions in the worksheet.
- Use the Activity videos, handouts, and resource links as you complete the hands-on activities. Follow along with the activity video and step by step instructions.
- Give the filled-out worksheet to your teacher at the completion of this lesson.
