An open source robot reinforcement learing plantform using stable-baselines and OpenAI Gym in Pybullet simulator.

This repo is just started, and only has quadruped robot motion imitation from google research now, but in the future it will have varity of robots, tasks and envs on this platform.

Install dependencies:

• Install MPI: sudo apt install libopenmpi-dev
• Install requirements: pip3 install -r requirements.txt

and it should be good to go.

To running the example, run the following command:

python3 OpenRoboRL/run.py --task imitation_learning_laikago

• --task can be imitation_learning_laikago or imitation_learning_minicheetah for now

For parallel training with MPI run:

mpiexec -n 8 python3 OpenRoboRL/run.py --task imitation_learning_laikago

• -n is the number of parallel.

Enables visualization or not, there is enable_rendering param in pybullet_sim_param.yaml can be set.

There are two yaml file in OpenRoboRL/config folder, pybullet_sim_param.yaml is the simulation params, which is not recommended to modify, training_param.yaml is the training params, the following is the meaning of some parameters:

• num_robot is the number of robots trained in parallel in the same simulator environment.
• mode can be either train or test.
• motion_file specifies the reference motion that the robot is to imitate. OpenRoboRL/learning/data/motions/ contains different reference motion clips.
• model_file specifies the pre-trained model that the robot is to imitate. OpenRoboRL/learning/data/policies/ contains different model.
• int_save_freq specifies the frequency for saving intermediate policies every n policy steps.
• the trained model and logs will be written to output/.
