FORWARD fd Blue-Bot moves forward in fixed-size units. A unit of one is about 6 inches or 15 cm). Blue-Bot quickly pauses after each unit of movement. This is great way to see 1-1 correlation.
BACK bk Blue-Bot moves backwards in the same way that it moves forward, moving in fixed units. For example bluebot.run [bk 1] would move Bluebot back 1 unit.
LEFT lt Blue-Bot turns left 45 or 90 degrees, depending what you tell it to do. For example rt 90 will turn right 90 degrees, or lt 45 will turn left 45 degrees.
RIGHT rt Blue-Bot turns right 45 or 90 degrees, depending what you tell it to do. For example rt 90 will turn right 90 degrees, or lt 45 will turn left 45 degrees.
WAIT no abbreviation This command corresponds to Blue-Bot's Pause button. Blue-Bot pauses in units of about two seconds. Therefore, the input to WAIT (which is a millisecond value) should be a multiple of 2000. Logo rounds wait times to the nearest multiple of two seconds.
REPEAT no abbreviation Blue-Bot has a simple built-in repeat feature that lets it execute a list of commands between 1 and 16 times. The REPEAT command cannot be nested.
