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:

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

The Bullet 2.86 has improved Python bindings, pybullet, for robotics, machine learning and VR, see the pybullet quickstart guide.

Furthermore, the PGS LCP constraint solver has a new option to terminate as soon as the residual (error) is below a specified tolerance (instead of terminating after a fixed number of iterations). There are optional multithreaded optimizations, thanks to lunkhound. There is preliminary support to load some MuJoCo MJCF xml files (see data/mjcf),see Bullet VR haptic experiments with a VR glove:

Bullet Physics SDK 2.83 is a first release using the new example browser. See the docs/BulletQuickstart.pdf how to get started.

Note that the example browser needs a bit more work and some old demos are not in the new example structures yes, this is a todo for a future release.
