FAQPage Schema

How do I create a URDF robot model for ROS simulation?▼

To create a URDF robot model for ROS simulation, define accurate link and joint hierarchies with appropriate visual, collision, and inertial properties. Ensure consistent frame placement and axis definitions to avoid misalignment and achieve stable physics in simulators.

Why does my URDF model fail to load correctly in Gazebo or RViz?▼

URDF models fail to load correctly in Gazebo or RViz due to improper joint and link management, incorrect inertia calculation, or mismatched visual and collision geometry pairing. Frame alignment and error-free parsing must be enforced to ensure stable physics.

What is the proper way to calculate inertia for URDF links?▼

The proper way to calculate inertia for URDF links involves defining accurate inertial properties within the link structure. This ensures correct dynamic behavior and stable physics during ROS-based simulation validation and manual robot design.

Do I need to pair visual and collision geometry in a URDF file?▼

Yes, you need to pair visual and collision geometry in a URDF file to prevent physics errors. Proper visual and collision geometry pairing alongside consistent frame alignment ensures error-free parsing and stable simulation behavior.

What is the minimum structure required to validate a URDF robot model?▼

The minimum structure required to validate a URDF robot model is a base link and one movable joint. After defining these elements, you can successfully validate the model in RViz or Gazebo for simulation.

Can I use URDF models for educational robotics demonstrations?▼

Yes, you can use URDF models for educational robotics demonstrations. They provide practical examples for robotics courses and project prototyping, helping students understand kinematics, joint definitions, and frame placement.
