RL training using Nvidia Omniverse

 How to run Isaac gym on my computer:

C:\Users\jynx4\AppData\Local\ov\pkg\isaac_sim-2023.1.1\isaac-sim.gym.bat --ext-folder D:\isaac\

This includes default robots. In order to run training on Pinky, many files must be created along with importing a .xacro or .urdf robot description into a USD stage.

Modify this file:

by adding "omni.isaac.sensor" = {} at the end.


Gait phases:
  1. Stance: the foot is in contact with the ground
    1. Loading: the foot transitions from non-contact to contact
    2. Travel: foot follows the opposite vector of the command
    3. Pre-swing: as the foot nears the end of its range of motion, it waits for 4 feet to be in contact with the ground
  2. Swing: the food is in the air
    1. Unloading: the foot transitions from non-contact to contact
    2. Position: the foot lifts to a minimum height for clearance while maintaining minimal distance from the center of the robot.
    3. Travel: moves to maximize its stride
    4. Pre-stance: waits until only 3 feet are in contact with the ground
