URDF Templates

Instructions

When working with URDF files:

1. Use the provided templates as starting points
2. Validate against the checklist in validation.md
3. Include safety annotations for joint limits
4. Add comments explaining each section

URDF Structure Overview

<robot name="robot_name">
  <!-- Links define physical parts -->
  <link name="base_link">
    <visual>...</visual>
    <collision>...</collision>
    <inertial>...</inertial>
  </link>

  <!-- Joints connect links -->
  <joint name="joint_name" type="revolute">
    <parent link="parent_link"/>
    <child link="child_link"/>
    <limit lower="-1.57" upper="1.57" effort="100" velocity="1.0"/>
  </joint>
</robot>

Safety Requirements

1. Always specify joint limits - Never leave limits undefined
2. Include inertial properties - Required for physics simulation
3. Add collision geometry - Required for safe simulation
4. Document mass values - Use realistic values
