Code for the papers:

Code structure:

A rough outline for the repository that might be useful for adding your own robot:

LearningHumanoidWalking/
├── envs/                <-- Actions and observation space, PD gains, simulation step, control decimation, init, ...
├── tasks/               <-- Reward function, termination conditions, and more...
├── rl/                  <-- Code for PPO, actor/critic networks, observation normalization process...
├── models/              <-- MuJoCo model files: XMLs/meshes/textures
├── trained/             <-- Contains pretrained model for JVRC
└── scripts/             <-- Utility scripts, etc.

Requirements:

Usage:

Environment names supported:

Task DescriptionEnvironment name
Basic Walking Task'jvrc_walk'
Stepping Task (using footsteps)'jvrc_step'

To train:

$ python run_experiment.py train --logdir <path_to_exp_dir> --num_procs <num_of_cpu_procs> --env <name_of_environment>

To play:

We need to write a script specific to each environment.
For example, debug_stepper.py can be used with the jvrc_step environment.

$ PYTHONPATH=.:$PYTHONPATH python scripts/debug_stepper.py --path <path_to_exp_dir>

What you should see:

Ascending stairs:
climb_up

Descending stairs:
climb_down

Walking on curves:
curve
