Functions of the various keys on the Pro-Bot keypad:

The arrow keys above the numbers:
Fd – go forward (you can specify the distance in cm, it moves 25 cm if you don’t specify measurements)
Example :
·      Fd 10 (Pro-Bot moves 10 cm forward)
·      Fd (No distance specified, so Pro-Bot moves forward 25 cm)
·
Bk – go backward (you can specify the distance in cm, it moves 25 cm if you don’t specify measurements)
Example :
·      Bk 10 (Pro-Bot moves 10 cm backward)
·      Bk (No distance specified, so Pro-Bot moves backward 25 cm)

Rt – turn right (note that it does not move forward along with the turn)
You can specify the angle in degrees; turns 90 degrees if no angle is specified.
Example:
·      Rt 60 (Pro-Bot turns 60 degrees to the right)
·      Rt (Pro-Bot turns 90 degrees to the right)

Lt – turn left (note that it does not move forward along with the turn)
You can specify the angle in degrees; turns 90 degrees if no angle is specified.
Example:
·      Lt 60 (Pro-Bot turns 60 degrees to the left)
·      Lt (Pro-Bot turns 90 degrees to the left)

Go – starts the program
Note: If you want the stop the program while it is running, press the Go button again.

Ps – pauses the program for a short time; after the pause, the program continues on its own.

Clear – delete the last key pressed on each line.

Rpt[  Repeat a command a specified number of times. Needs to be accompanied by the closing bracket ] after the sequence of statements. Else the repeat will run 255 times.
Example:
·      Rpt[ 4 Fd 5 ]  (Pro-Bot will repeat the Fd 5 statement 4 times. So it will move a total of 20 cm before it stops.)

– closing bracket for a repeat command

Proc - short for “procedure”. A procedure is a small program used to perform a specific function. Pro-Bot can store up to 32 procedures in its memory.

Numbers keys 0-9 – used for specifying measurements

Menu – provides access to a number of other functions within Pro-Bot. These include a range of special commands for editing the program, configuration options, etc.

Up and Down Arrow keys near Menu button – used to scroll up or down the commands / menu options seen on the LCD screen.
