Description

Make a three-dimensional bipedal robot walk forward as fast as possible, without falling over.

Environment

Observation

The OpenAI gym environment hides first 2 dimensions of qpos returned by MoJoCo. They correspond to x and y coordinate of the robot root (abdomen). The reason is this quantity can grow boundlessly and their absolute value does not carry any significance. If you want to obtain the full state just use env.env.state_vector() and you will get a 47-dimensional vector containing qpos and qvel. refer to mujoco_env.py. All the joint angles are in radians.
