Move Drive Toward Object

Format:

move drive toward object <object name> {stop <distance> <units>}

Parameters:

object name specifies the filename of the object to move toward

{} The curly braces indicate the use of the word 'stop'

The stop distance is optional. There is a built-in default of 2 feet.

Examples:

move drive toward object Coke stop 6 in

move drive toward object 'back door'

Move Drive Toward Color

Format:

move drive toward color <r> <g> <b> {stop <percentage> {%}}

This is similar to the rotate toward color command, but you can optionally specify a

percentage value to make the robot stop when that percentage of the screen is filled by the

chosen color.

Examples:

move drive toward color 0 255 0 stop 10 %

move drive toward color 0 255 0 stop 10

move drive toward color 128 128 128
