Title: Add Support for URDF File Loading for UR10 CB3 in Pybotics

Body: Hello Pybotics Team,

I'd like to request a feature for Pybotics: the ability to directly load URDF (Unified Robot Description Format) files, especially for the UR10 CB3 robot model. Currently, Pybotics supports MDH files, but URDF has become a standard in the robotics community, and many users, including myself, would greatly benefit from this feature.

Key Points:

• URDF for Wider Compatibility: URDF is widely used and supporting it would make Pybotics more versatile and user-friendly.
• Specific Need for UR10 CB3 Model: The UR10 CB3 model is crucial for my projects, and direct URDF support would greatly facilitate its integration into Pybotics.

I believe this addition would be a valuable enhancement to Pybotics, benefiting a wide range of users.

Thanks for considering this request!

Best, Niklas
