madison_wcb.wcb module

madison_wcb.wcb.brush_down()

Puts the brush in its “down” position, so that it touches the paper.

madison_wcb.wcb.brush_up()

Puts the brush in its “up” position, so that it doesn’t touch the paper.

madison_wcb.wcb.cleanup()

IMPORTANT: Call this function at the end of your program.

madison_wcb.wcb.get_color(index)

Dips the brush in paint.

Arguments:

index - an integer between 0 and 7, inclusive. Tells the bot which color you want.

madison_wcb.wcb.get_distance_traveled()

Returns a number like 123, representing the distance that the brush has traveled since the last time that it was dipped in paint or water.

NOTE: Only tracks movement triggered by calls to the move_forward() function. Movement caused by move_to() is _not_ recorded.

This number represents the number of “steps” that the brush has traveled, not the number of inches or centimeters; you’ll have to do some experimentation on your own to figure out e.g. how many centimeters 100 steps is equal to.

madison_wcb.wcb.get_position()

Returns the brush’s current position.

Return value:

A list like [-102, 50] representing the brush’s current [x, y] position.

madison_wcb.wcb.get_x()

Returns the brush’s current x-coordinate.

Return value:

A number between -250 and 250, represnting the brush’s current horizontal position.

madison_wcb.wcb.get_y()

Returns the brush’s current y-coordinate.

Return value:

A number between -180 and 180, representing the brush’s current vertical position.

madison_wcb.wcb.initialize()

IMPORTANT: Call this function at the beginning of your program.

madison_wcb.wcb.move_forward(num_steps)

Moves the brush forward a few steps in the direction that its “turtle” is facing.

Arguments:

num_steps - a number like 20. A bigger number makes the brush move farther.

madison_wcb.wcb.move_to(x, y)

Moves the brush to a particular position.

Arguments:

x - a number between -250 and 250. y - a number between -180 and 180.

madison_wcb.wcb.park()

Park the watercolorbot’s brush in the top-left corner.

madison_wcb.wcb.point_in_direction(angle)

Points the brush’s “turtle” in the direction of the angle specified.

Arguments:

angle - a number between 0 and 360.

madison_wcb.wcb.set_reinking_distance(distance_in_cm)

Sets the number of centimeters the bot will draw before re-inking the brush with the last used paint.

Arguments:

distance_in_cm - an integer representing a number of centimeters.

madison_wcb.wcb.turn_left(relative_angle)

Turns the brush’s “turtle” to the left.

Arguments:

relative_angle - a number like 10.

A bigger number makes the turtle turn farther to the left.

madison_wcb.wcb.turn_right(relative_angle)

Turns the brush’s “turtle” to the right.

Arguments:

relative_angle - a number like 10.

A bigger number makes the turtle turn farther to the right.

madison_wcb.wcb.wash_brush()

Wash the brush in water.
