Recommended for Middle School through High School.
In this activity, students recreate the functionality of Mode C–Line Following of the Default Program. Students learn how to read data from the Line-Follower Sensor and use that data to guide mBot’s motion. During this activity, students build and try two different types of line-following programs in addition to testing mBot on courses of varying design.
- Practice writing code and troubleshooting when problems arise.
- Learn how the Line-Follower Sensor works.
- Practice using variables, "if-then-else" blocks, and loops in code.
- Explore the difference between edge-following and traditional line-following programs for mBot.
Sensors and Equipment
This experiment features the following Vernier sensors and equipment.
You may also need an interface and software for data collection. What do I need for data collection?
Computer Science Teachers Association (CSTA) Standards
- Create clearly named variables that represent different data types and perform operations on their values.
- Design and iteratively develop programs that combine control structures, including nested loops and compound conditionals.
- Decompose problems and subproblems into parts to facilitate design, implementation, and review of programs.
- Systematically test and refine programs using a range of test cases.
- Document programs in order to make them easier to follow, test, and debug.
