drive over markers

Block

Description

This function was designed for the Zumitown Mat. Zumi will drive over the specified number of alternating black and white horizontal lines at least 2 centimeters wide. Zumi will stop when the number of markers have been crossed or if the timeout ends, whichever is first. (Avoid making the speed very high, zumi will most likely overshoot since it has a lot of speed)

Parameters

markers: An integer number of road markers to drive over
speed: Positive integer value between 0 and 80
IR_threshold: An integer IR threshold value 0-255 for the bottom left IR sensors to detect black or white.
time_out: A float value for the timeout in seconds

Returns

None

Example

Drive over 5 markers with a timeout of 3 seconds.
