The Problem (3 paragraphs)

MuJoCo is the fastest-growing robotics simulator

Converting URDF to MJCF is painful (./compile is buggy, urdf2mjcf ignores off-diagonal inertia, mesh paths break)

You just want to convert and start training your RL agent

The Solution (show curl + Python code)

curl -X POST .../api/urdf/convert-format?target=mjcf \

-H "X-Api-Key: rk_..." -F "file= @robot .urdf"

import roboinfra

client = roboinfra.Client("rk_...")

result = client.urdf.convert_format("robot.urdf", "mjcf")

with open("robot.xml", "w") as f:

f.write(result.converted_xml)

Real Example (use your preview_test_arm.urdf)

Show the input URDF (6 links, 5 joints)

Show the output MJCF (with actuators, floor, lighting)

"This would take 2-3 hours manually.…
