2 cards from this section. Quick, good the night before a test.
What is the primary function of IR sensors in line-following robots?
Think about how robots see the line.
Write a simple logic statement for stopping a robot when an obstacle is detected.
Consider comparing the distance sensor reading to a critical threshold.
What is the main purpose of basic logic in autonomous navigation?
Think about how robots react to their environment.
True or False: Line-following robots use ultrasonic sensors.
Consider what sensors are typically associated with line-following behaviour.
Design a line-following robot using two IR sensors that can handle curves as well as straight lines. Write the logic needed for this function.
Consider how curves would affect sensor detection.
Imagine a scenario where a robot’s IR sensors fail and cannot detect the line. Discuss how you would program the robot to still navigate safely.
Think about alternative strategies for the robot to minimize error.
