@Athena Can you show me how to add and take away data to and from a multidimensional array containing x, y, z coordinates of motors from an outside source. I think you will be using push command to do this.

Certainly! In JavaScript or Python, you can use the push() method to add items to an array, and you can use various methods such as splice() or pop() to remove items. Here's a basic example of how you might manage a multidimensional array containing x, y, z coordinates for motors:

// Initialize a multidimensional array
var motorCoordinates = [];

// Function to add a new set of coordinates to the array
function addCoordinates(x, y, z) {
  motorCoordinates.push([x, y, z]);
}

// Function to remove a set of coordinates from the array by index
function removeCoordinates(index) {
  if (index >= 0 && index < motorCoordinates.length) {
    motorCoordinates.splice(index, 1);
  } else {
    console.log("Index out of bounds");
  }
}

// Example usage:
addCoordinates(10, 20, 30); // Add first set of coordinates
addCoordinates(40, 50, 60); // Add second set of coordinates
console.log(motorCoordinates); // View the array

removeCoordinates(0); // Remove the first set of coordinates
console.log(motorCoordinates); // View the array after removal

In this example, motorCoordinates is an array that will store sub-arrays of coordinates. The addCoordinates function adds a new set of coordinates to the motorCoordinates array. The removeCoordinates function removes a set of coordinates at a specified index.

If you want to remove the last item from the array, you can use the pop() method, which doesn't require an index:

// Function to remove the last set of coordinates from the array
function removeLastCoordinates() {
  motorCoordinates.pop();
}

To integrate this with an external source, you would need to have a way to receive the coordinates (e.g., from a file, a web API, user input, etc.) and then call addCoordinates with the received data. Similarly, you would determine which coordinates to remove based on some external criteria or commands.

Please note that in the context of Synthiam ARC, you would use JavaScript or Python within the scripting environment provided by ARC, and you would interact with the ARC API to control the robot's hardware accordingly.

@Athena I tried to run your program of the previous question and it returned this to me

Execution Error Line 21 Col 0 - console is not defined which was referring to this-   console.log(motorCoordinates); // View the array It seems like you had it correct, any idea what the problem may be?

In the context of Synthiam ARC, the JavaScript or Python environment provided for scripting may not support all features available in standard web browsers or Node.js environments. The console.log() function is typically used for logging in web browsers and Node.js, but it may not be available in ARC's scripting environment.

Instead of using console.log(), you can use the print() function provided by ARC to output text to the debug window. Here's how you can modify the code to use print():

// Initialize a multidimensional array
var motorCoordinates = [];

// Function to add a new set of coordinates to the array
function addCoordinates(x, y, z) {
  motorCoordinates.push([x, y, z]);
}

// Function to remove a set of coordinates from the array by index
function removeCoordinates(index) {
  if (index >= 0 && index < motorCoordinates.length) {
    motorCoordinates.splice(index, 1);
  } else {
    print("Index out of bounds");
  }
}

// Example usage:
addCoordinates(10, 20, 30); // Add first set of coordinates
addCoordinates(40, 50, 60); // Add second set of coordinates
print(JSON.stringify(motorCoordinates)); // View the array

removeCoordinates(0); // Remove the first set of coordinates
print(JSON.stringify(motorCoordinates)); // View the array after removal

In this modified code, I replaced console.log() with print() and used JSON.stringify() to convert the array to a string for printing. This should work within the ARC scripting environment and allow you to see the output in the debug window.

Remember to test the code within ARC's scripting feature to ensure compatibility with the ARC environment. If you encounter any further issues, you may need to consult the ARC documentation or support resources for additional guidance on the scripting capabilities available in ARC.

@Athena yes this sent it to the log screen much better. Thanks

You're welcome! I'm glad to hear that the solution worked for you. If you have any more questions or need further assistance with your ARC project, feel free to ask. Happy robot building!

@Athena I'd like to expand on conversation #13. What is the code to have the motors go to Widget A or Gadget B. In some case you may not know the QR code and only have the name to work with.

Use the Auto Position robot skill. It has a good manual
