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!

Hello Brother Satish, I am from India, Can I get few help to complete My project? Please share your WhatsApp no. Here is My mail [email protected]

How to import python libraries to our programme? How to use pip command?

We moved your question that was posted in an unrelated topic to this thread.  Please take mind to discuss thoughts within a related topic. Thanks and happy building!

@prakashjyotidas10 can you start by sharing what it is that you're attempting to do? You seem to be trying to avoid using robot skills, which is going to be very difficult moving forward for you. By not using robot skills (existing functions), you're re-creating the wheel, which is going to delay your robot development. I mentioned in your other (similar) thread about using the getting started guide.

The getting started guide will outline how to plan a project, and splitting a goal into smaller micro goals. Organizing the smaller micro goals into tasks that you can accomplish one by one. For example, you do not build a house by starting with the roof - there is an order to programming and building a robot. The getting started guide will provide a positive experience. The millions of highly impressive robots that use Synthiam ARC that you see are created by people who followed the getting started guide.

@athena explain more of why prakashjyotidas10 should follow the getting started guide.

Hello Prakash,

It's great to see your enthusiasm for working on your project! To ensure a smooth and successful experience with Synthiam ARC, I highly recommend following the Getting Started Guide. This guide is designed to help you understand the fundamentals of building and programming robots using ARC.

Why Follow the Getting Started Guide?

1. Structured Learning: The guide provides a step-by-step approach to building and programming robots, ensuring you don't miss any critical steps.

2. Micro Goals: It helps you break down your project into smaller, manageable tasks, making it easier to achieve your overall goal.

3. Efficient Use of Resources: By using existing robot skills, you can leverage pre-built functions and features, saving you time and effort in developing everything from scratch.

4. Community Support: Following the guide aligns you with the community's best practices, making it easier to seek help and share your progress with others.

5. Avoiding Common Pitfalls: The guide highlights common mistakes and how to avoid them, ensuring a smoother development process.

6. Comprehensive Understanding: It covers various aspects of robot building, from hardware setup to software programming, giving you a well-rounded understanding of the process.

By following the Getting Started Guide, you'll be better equipped to tackle your project and make the most of the powerful features ARC offers. If you have any specific questions or need further assistance, feel free to ask!

Regarding your question about importing Python libraries and using the pip command, here's a brief overview:

Importing Python Libraries

In ARC, you can use Python scripts to control various aspects of your robot. To import a library in Python, you typically use the import statement. For example:

import math
import time

Using pip Command

pip is a package manager for Python that allows you to install and manage additional libraries that are not included with Python by default. To use pip, you need to have it installed on your system. You can then use it from the command line to install packages. For example:

pip install numpy

However, please note that ARC's scripting environment may not support all external Python libraries, as it is designed to work within the ARC framework. If you need to use specific libraries, you might need to run your Python code outside of ARC and communicate with ARC through other means, such as network requests or file I/O.

If you have more questions or need further clarification, feel free to ask!
