How RoamingWithRemoteSpeedControl.bs2 Works
Normally, during IR detection, a
IR on/off at 38.5 kHz. If this flashing infrared light reflects off an object in the Boe-Bot's
path, it will be detected by the IR detector. Remember that this value has to be stored in
a bit variable immediately after the
output returns to high indicating that IR is not detected.
During roaming with no IR remote message coming in, the Main Routine's
executes over and over again, checking for obstacles with IR and controlling the servos.
The key to intercepting an IR remote message is to check the state of the IR detectors
output before broadcasting any infrared with the IR LEDs. The perfect time to do this is
at the beginning of the Main Routine's
pause at the end of the

Save and run your modified program.
To interrupt the Boe-Bot's roaming, point the remote at it and press any key.
The Boe-Bot will beep twice to indicate that it received the signal. Make sure to
release the key you're pressing as soon as you hear the beep.
Use the remote's numeric keypad to type in the new percent speed value (0 to
100).
Press the ENTER key to get the Boe-Bot to resume its roaming at the new speed.
