|Turn on Blue-Bot.
Log in to Terrapin Logo.
Select Tools/Connect to Bluetooth.
Getting started with Blue-Bot and Logo
Make sure you are connected via Bluetooth.
Try these first 3 simple commands. Commands can provide valuable information.
Ask Blue-Bot if it is connected to Bluetooth. If it is
connected, it will return TRUE. If not it will return FALSE.
TRUE and FALSE conditions are an important coding/programming concept.
Check the battery level. Bluebot will return how much
charge Blue-Bot has, with 1.0 being 100 percent charged.
This is a great opportunity to talk about decimals, place value, and percentage.
Clear the memory. Blue-Bot will clear any commands that are in its memory.
It’s time to get Blue-Bot on the move!
Move that Bot!
To move the Blue-Bot, always start with
bluebot.run. This command won’t do by anything itself. You have to tell Blue-Bot what to run.
bluebot.run with a space, and then an open bracket. Type a Logo command, then a close bracket.
Press Return/Enter. Try the example shown on the right
bluebot.run [fd 1] and press Return/Enter.
bluebot.run [fd 1]
Note: Many Logo commands can be entered by typing the full command or an abbreviation. This can be very helpful, especially for younger programmers.
Let’s add some commands!
Let’s add another 2 steps to your program. Add the following:
rt 90 fd 1.
Your program should look like the example below. Try it!
bluebot.run [fd 1 rt 90 fd 1]
|FORWARD||fd||Blue-Bot moves forward in fixed-size units. A unit of one is about 6 inches or 15 cm). Blue-Bot pauses slightly after each unit of movement. This is great way to see 1:1 correlation.|
|BACK||bk||Blue-Bot moves backward in the same way that it moves forward, moving in fixed units. For example, bluebot.run [bk 1] would move Blue-Bot 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; 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; lt 45 will turn left 45 degrees.|
|WAIT||no abbreviation||This command corresponds to Blue-Bot’s
|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
Terrapin Logo commands are not case-sensitive.
