Ir Beacon & Ez-B

This Script may be of interest to anyone setting up the Pololu ir Beacon with EZ-B
while I control 2 servo motors it should be easy to adapt to a movement panel

:forward
SLEEP(10)
IF (GETDIGITAL(D11)=0)
servo(d0, 48)
GOTO(forward)
ELSEIF (GETDIGITAL(D11)=1)
SERVO(D0, 54)
ENDIF
:reverse
IF (GETDIGITAL(D13)=0)
SERVO(D0, 62)
GOTO(REVERSE)
ELSEIF (GETDIGITAL(D13)=1)
SERVO(D0, 54)
SLEEP(10)
ENDIF
:Turnleft
SLEEP(10)
IF (GETDIGITAL(D12)=0)
SERVO(D1, 50)
GOTO(TURNLEFT)
ELSEIF (GETDIGITAL(D12)=1)
SERVO(D1, 45)
SLEEP(10)
ENDIF
:TURNRIGHT
IF (GETDIGITAL(D14)=0)
SERVO(D1, 38)
GOTO(TURNRIGHT)
ELSEIF (GETDIGITAL(D14)=1)
SERVO(D1,45)
ENDIF
GOTO(FORWARD)

@Rich, thanks for you help

Not a problem, I'm happy to help. Your posts inspired my next scripting tutorial idea - the If command and all of it's conditions.

By the way if you use the code tag in your posts

Code:


it looks better :)


use the word code inside square brackets.

Also, you can use just an ELSE rather than ELSEIF. I know I used ELSEIF in my first example to you, both ways work but ELSE is less typing:)

Code:


IF (GETDIGITAL(D11)=0)
  servo(d0, 48)
  GOTO(forward)
ELSE
  SERVO(D0, 54)
ENDIF



I wondered what it was for and have to admit I'm still not entirely sure what it does (well, I know what it does I don't know the why). It'll loop around forward until a status chance, then look around reverse etc. Is that what it is meant to do?

As for adapting for a movement panel, just use the commands
Forward([speed], [milliSeconds])
Reverse([speed], [milliSeconds])
Left([speed], [milliSeconds])
Right([speed], [milliSeconds])

(Would need a Movement Panel set up in ARC otherwise it doesn't know what to move)

Using it as a test for locating battery charger

I us two servos to operate a joystick of a motorised wheelchair this script allows me to walk off with the second beacon and the robot will then follow me.
Hide the Beacon and it will stop.
