Bullet Physics SDK/bullet3: Release 2.87

Name: bullet3

Owner: Bullet Physics SDK

Release: Bullet 2.87 with pybullet robotics Reinforcement Learning environments

Released: 2017-09-29

License: NOASSERTION

Release Assets:

Bullet 2.87 has improved support for robotics, reinforcement learning and VR. In particular, see the "Reinforcement Learning" section in the pybullet quickstart guide at http://pybullet.org . There are also preliminary C# bindings to allow the use of pybullet inside Unity 3D for robotics and reinforcement learning.

Here are some videos:

• Minitaur pybullet trained with TF Agents PPO, improved motor model, randomization
• pybullet Ant trained using TensorFlow Agents
• pybullet KUKA grasp training/enjoy using Tensorflow+OpenAI gym+baselines DQN

Some example training the pybullet_pendulum using TensorFlow Agents PPO: pip install pybullet, agents, tensorflow, gym

python -m pybullet_envs.agents.train_ppo --config=pybullet_pendulum --logdir=pendulum tensorboard --logdir=pendulum --port=2222 python -m pybullet_envs.agents.visualize_ppo --logdir=pendulum/xxxxx --outdir=pendulum_video
