R.)

Release (servoPort) Release a servo from holding its position Example: Release(D14)

ReleaseAll ( [boardIndex] ) Release all servos from holding their position BoardIndex is optional, and specified the EZ-B board to use Example: ReleaseAll()

REPEAT Repeats the code between REPEAT and ENDREPEAT as many times as specified. Assigns the number of times to the specified variable. Example: REPEAT($x, 0, 5, 1) Print(x= + $x) ENDREPEAT

REPEATUNTIL Repeats the code between REPEATUNTIL and ENDREPEATUNTIL until the specified condition is TRUE. Example: REPEATUNTIL($second = 30) Print(Second= + $second) Sleep(500) ENDREPEAT

REPEATWHILE Repeats the code between REPEATWHILE and ENDREPEATWHILE until the specified condition is FALSE. Example: REPEATUNTIL($second > 50) Print(Second= + $second) Sleep(500) ENDREPEAT

Return() Return from a Goto() If you jump to a position of code with a Goto(), the Return statement will allow you to return back to that piece of code following the last Goto() statement. If you attempt to Return() with an empty stack, nothing will happen. The script will ignore the Return() statement. Example: Return()

Reverse( [speed], [milliSeconds] ) Using a Movement Panel Control, this will start your robot in the Reverse direction. Optionally, you can provide the speed and/or number of milliseconds to move. You will require at least one Movement Panel to be configured within the project. This function will control that movement panel. Speed is a number between 0 and 255 Example: Reverse() Example: Reverse(200) Example: Reverse(255, 5000)

Right( [speed], [milliSeconds] ) Using a Movement Panel Control, this will turn your robot right. You will require at least one Movement Panel to be configured within the project. This function will control that movement panel. Optionally, you can specify the speed and/or number of milliseconds to turn. Speed is a number between 0 and 255 Example #1: Right() Example #2: Right(200) Example #2: Right(200, 5000)

RoboQuad( RoboQuadCommand ) Send a command to a RoboQuad connected on port D1 on EZ-B 0. Find the available RoboQuad commands further down in this document. Example: RoboQuad( Walk_Forward ) Example: RoboQuad( Left_Turn_Roll )

RoboSapien( RoboSapienCommand ) Send a command to a RoboSapien connected on port D1 on EZ-B 0. Find the available RoboSapien commands further down in this document. Example: RoboSapien( WalkForward ) Example: RoboSapien( LeftArmUp )

RollLeft( [milliSeconds] ) Using the servo port settings from a Movement Panel Control, this will roll your drone robot left Optionally, you can specify the number of milliseconds to turn. Example #1: RollLeft() Example #2: RollLeft(1000)

RollRight( [milliSeconds] ) Using the servo port settings from a Movement Panel Control, this will roll your drone robot right Optionally, you can specify the number of milliseconds to turn. Example #1: RollRight() Example #2: RollRight(1000)

Roomba( cmd ) Execute the specified command on a connected Roomba Vacuum on Port D0 and EZ-B 0. Look for the available Roomba commands further below in this document. You may also add the Roomba Movement Panel for graphical controls. Example: Roomba(init) Example: Roomba(SideBrushOn)

Round( value, decimals ) Returns the math Round() of a number Returns the number rounded to the specified decimal places Example: $x = Round($pi, 2) Example: $x = Round(9.3848291, 1)

RoboQuad Commands Supported on the EZ-B v3 only, the D1 port can be used to connect to the IR wire of some WowWee robots. Due to multiple hardware revisions of the robots, these functions are not always compatible and therefore this feature has been discontinued in the EZ-B v4.
