Implements a so-101 robotic arm simulaltion environment for the EnvHub.

• Observation is a np.ndarray.shape = (640, 480, 3).
• Action is a np.ndarray.shape = 6 where each element represents the joint control.
• Reward is the euclidian distance between the gripper and the red block, which it needs to minimize.

Basic usage

SO101Env(
    xml_pth=Path("assets/SO-ARM100/Simulation/SO101/scene_with_cube.xml"), 
    obs_w=640, 
    obs_h=480)
env = gym.make(
    "base-sO101-env-v0",
)
try:
    obs, _ = env.reset()
    for i in range(10):
        action = env.action_space.sample()
        obs, reward, terminated, truncated, info = env.step(action)
        if terminated or truncated:
            break
finally:
    env.close()

ToDo

Things I want to do

• Make a hardcoded policy that can pick up the block.
• First attempt of training a model.
