Arduino Mega 2560 driver could not be found on Windows 7

Issue: Arduino Mega 2560 driver could not be found on Windows 7
Solution: Simply go to Start - right click on Computer - Properties - Device Manager -  Under Other Devices, Find Arduino Mega 256 - right click and choose update driver - Choose Browse computer for driver software - Click Browse and Navigate to your Arduino home folder(where you installed Arduino) and choose drivers folder and  click Next. The windows 7 would find the right driver inside the folder.

Happy coding with Arduino :-)

Breaking a loop in Rapid ABB

To break an infinite loop in Rapid ABB try the following code:

WHILE (TRUE)
      Counter = Counter + 1;
      IF (Counter = 5) THEN
           Return;
     ENDIF
ENDWHILE

Reseting program pointer, ABB PC SDK

ResetProgramPointer method

Using ResetProgramPointer you can set the program pointer to the main entry point of the task.

VB:

aTask.ResetProgramPointer()

C#:

aTask.ResetProgramPointer();

Stop [ \NoRegain ], ABB RAPID

MoveL point_1, v1000, z10, tool1;
TPWrite “Jog the robot to the position for pallet corner 1”;
Stop \NoRegain;
p1_read := CRobT();
MoveL point_2, v500, z50, tool1;

Program execution stops with the robot at point_1. The operator jogs the robot to p1_read. For the next program start, the robot does not regain to point_1, so the position p1_read can be stored in the program

3pi robot LCD from Arduino

What is a 3pi robot ?

What is an Arduino board ?

What is an AVR Atmel Micro-controller ?

----------------

#include

OrangutanLCD lcd;

void setup()               // run once, when the sketch starts
{

}

void loop()                // run over and over again
{
  // avoid clearing the LCD to reduce flicker
  lcd.gotoXY(0, 0);
  lcd.print("Line 1");
  lcd.print("  ");              // overwrite any left over digits
 
  lcd.gotoXY(0, 1);

  lcd.print("Line 2");

  lcd.print("  ");              // overwrite any left over digits

}

3pi motor control from Arduino

What is a 3pi robot ?
What is an Arduino board ?
What is an AVR Atmel Micro-controller ?
----------------
#include

OrangutanMotors motors;

void setup()               // run once, when the sketch starts
{

}

void loop()                // run over and over again
{
  // note that the following line could also be accomplished with:
  // int pot = analog.read(7);
  //int pot = analog.readTrimpot();    // determine the trimpot position
  int motorSpeed1 = 25;  // turn pot reading into number between -256 and 255
  int motorSpeed2 = 0;  // turn pot reading into number between -256 and 255

// Minus - Zero -> back to right (turn around one point)
// Zero - Minus -> Back to leftt (turn around one point)
// Positive - Zero -> front to right (turn around one point)
// Zero - Positive -> front to left (turn around one point)

// Speed1 < Speed2 -> back to right
// Speed1 > Speed2 -> Back to leftt
// Speed1 > Speed2 -> front to right
// Speed1 < Speed2 -> front to left
// looking at robot from back ->  left number goes to left motor & right goes to right motor
motors.setSpeeds(motorSpeed1,motorSpeed2);
}
