Usage

Isaac Gym

bash

# Clone and install Isaac Gym, then:
conda activate gym
python isaacgym_visualize.py --animate --motion-mode sequential --duration 33 --fps 30

Isaac Lab

bash

conda activate sim4
python isaaclab_record_demo.py usd/wheel_robot_lab.usd \
  --headless --enable_cameras --motion-mode sequential --duration 20 --fps 24

Load URDF in Python

python

import yourparser  # e.g. urdfpy, yourdfpy, pybullet
robot = yourparser.load("robot_model_v2/urdf/wheel_robot.urdf")
