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.…
