The xrobo_calibration project provides a robust framework for calibrating robotic systems. It supports tools and methodologies for determining transformations between key components, such as cameras, robotic arms, and mobile base using calibration patterns like chessboards or markers.

• Camera calibration (xrobot_camera_calib)
• Robotic arm calibration (xrobot_arm_calib)
• Mobile base calibration (xrobot_mobile_base_calib)

pip install xrobo_calibration

from xrobo_calibration import calibrate

calibrate(robot_model, sensor_data)

The notebooks/ directory contains Jupyter notebooks for tutorials and visualizations. These notebooks demonstrate how to use the package and provide tools to visualize calibration results.

In addition to the basic package tutorials, the notebooks/detailed_tutorials/ folder contains advanced topics, including:

• 3D Transformation Basics: Understand the mathematics and visualization of transformations.
• Kinematics Primer: Learn forward and inverse kinematics for robotic arms.
• Calibration Algorithms: Dive into advanced calibration techniques like least squares.

1. Install JupyterLab:

   pip install jupyterlab
   

2. Launch the notebooks

jupyter-lab notebooks/detailed_tutorials/

• Keeps basic tutorials clean and focused on package usage.
• Provides a dedicated space for users interested in deeper learning or advanced techniques.
• Offers a foundation for community contributions to advanced topics.

Let me know if you need help creating any specific tutorial content!

1. Install JupyterLab:

   pip install jupyterlab

2. Launch the notebooks:

   jupyter-lab notebooks/
   
   

The data/ folder contains sample images, point clouds, and configuration files for use with tutorials and visualizations.

• images/: Sample images for camera calibration (e.g., chessboard images).
• point_clouds/: Example .pcd files for 3D object alignment.
• configs/: Configuration files for cameras, robotic arms, and mobile bases.
• mobile_base/: Odometry logs and wheel configuration files for mobile base calibration.

You can load the data programmatically using helper functions:

from xrobot_calibration.common.data_utils import get_sample_data_path
path = get_sample_data_path() + "/images/chessboard_01.jpg"
