UR_OnRobot_Camera

This project is an automation script for capturing images from the Universal Robot (UR5e) camera. The script interacts with the UR5e robot's web interface and captures images from the camera, which can be used for various applications like quality inspection, and real-time monitoring. The script automates browser actions and Python for processing and saving images.

Overview

This automation script captures images from the OnRobot Eyes that is connected Universal Robot (UR5e), interacting with its web interface. It performs a various of actions like logging into the robot’s control interface (via the OnRobot Compute Box web interrface), navigating to the camera section, and capturing images of the robot’s workspace.

How to Use

1. Power on the Robot:

   • Ensure the Universal Robot (UR5e) and the OnRobot Compute Box are powered on and connected to the network.

2. Clone the Repository:

   •     git clone https://github.com/UofI-CDACS/UR_OnRobot_Camera
     

3. Install the Dependencies:

   •     pip install -r requirements.txt
     

4. Edit the Script Configuration:

   • Open the main.py file and replace the IP address of the UR robot.
     • Example:

       driver.get("http://192.168.1.100")

5. Run the Script:

   • Execute the script to start capturing images:

     python capture_images.py

6. Image Output:

   • The captured images will be saved in the images/ directory, with filenames indicating the type of image captured (e.g., Image_1.png, Image_2.png).

Features

• Automated Image Capture:

  • Captures images from the UR5e camera automatically through the web interface.

• Smooth Navigation:

  • Uses Selenium for web automation to navigate through the robot’s interface and interact with buttons, tabs, and other elements.

• Screenshot Saving:

  • Saves screenshots of the full page and specific regions of interest (e.g., the camera output).

• Error Handling:

  • In case of any issues (e.g., login failure, element not found), the script saves an error screenshot for debugging purposes.

Requirements

Software

• Python 3.10
• Selenium
• Chrome WebDriver (compatible with the version of Google Chrome that you have installed)
• pyautogui (for additional screenshot handling, for capturing)

Hardware

• Universal Robot UR5e
• OnRobot RG2 Gripper
