Hello Satish,

To control the servos connected to the EZ-InMoov Robot Head from a Python script running outside of the ARC environment, you would need to establish a communication link between your external Python script and the ARC software. Here are a few approaches you can consider:

1. ARC Web Server:

   • ARC has a built-in web server feature that allows external applications to send HTTP requests to control robot skills. You can use this feature to send commands from your Python script to ARC.
   • You can enable the web server in ARC and use Python's requests library to send HTTP requests to control the servos.

2. Serial Communication:

   • If your EZ-B controller supports serial communication, you can use Python's pyserial library to send commands directly to the EZ-B controller.
   • This would require you to implement the EZ-B communication protocol in your Python script to send the appropriate commands for servo control.

3. Custom Robot Skill:

   • You can create a custom robot skill in ARC that listens for commands from your Python script. This skill can then translate those commands into servo movements.
   • This approach requires some development within ARC to create the custom skill.

4. Network Communication:

   • If your setup allows, you can use network sockets to communicate between your Python script and ARC. This would involve setting up a server-client architecture where ARC listens for commands from your Python script.

For detailed guidance on setting up any of these methods, you can refer to the ARC API documentation and explore the options that best fit your requirements.

If you have any specific questions or need further assistance with any of these methods, feel free to ask!

Thank you. Can you provide an example Python script that leverages the ARC web server?

Hi Athena,

Can you provide an example Python script that leverages the ARC web server?

Thanks, Satish

Hello Satish,

Certainly! Below is an example Python script that uses the requests library to send an HTTP request to the ARC web server to control a servo. This example assumes that you have the ARC HTTP Server skill configured and running.

First, ensure you have the requests library installed. You can install it using pip if you haven't already:

pip install requests

Here's a simple Python script to control a servo:

import requests

# Replace with your ARC HTTP server's IP address and port
arc_ip = "192.168.0.1"
arc_port = 80
password = "admin"  # Replace with your ARC HTTP server password if set

# Define the servo port and position
servo_port = "D0"  # Example servo port
servo_position = 90  # Example position (1 to 180)

# Construct the URL for the HTTP request
url = f"http://{arc_ip}:{arc_port}/Exec?password={password}&script=Servo({servo_port},{servo_position})";

# Send the HTTP request to ARC
response = requests.get(url)

# Check the response
if response.status_code == 200:
    print("Servo command sent successfully!")
else:
    print(f"Failed to send servo command. Status code: {response.status_code}")

Steps to Use the Script:

1. Configure the ARC HTTP Server:

   • Make sure the HTTP Server skill is added to your ARC project and is running.
   • Note the IP address and port number of the ARC HTTP server.

2. Update the Script:

   • Replace arc_ip with the IP address of your ARC HTTP server.
   • Replace arc_port with the port number if it's different from the default (80).
   • Update the password variable if you have set a password for the HTTP server.
   • Set the servo_port to the port your servo is connected to.
   • Set the servo_position to the desired position (between 1 and 180).

3. Run the Script:

   • Execute the Python script to send the command to ARC and control the servo.

This script sends a command to move a servo to a specified position using the ARC HTTP server. You can modify the script to send different commands or control multiple servos as needed.

If you have any questions or need further assistance, feel free to ask!
