1.robosuite的相关资料

• 是基于MuJoCo的机器人学习方针环境，提供一套基准环境，MuJoCo官方DeepMind长期支持，是通过模拟环境推进机器人智能倡议项目（ Advancing Robot Intelligence through Simulated Environments (ARISE) Initiative）的一部分。
• 是LIBERO的底层环境
• 基本介绍博文
• 简单运行和搭建简单环境的博文
• 官方网站
• 官方文档

2.robosuite最基本demo

• 创建一个简单的抓取任务环境，并可视化演示随机动作

import numpy as np
import robosuite as suite# create environment instance
env = suite.make(env_name="Lift", # try with other tasks like "Stack" and "Door"robots="Panda",  # try with other robots like "Sawyer" and "Jaco"has_renderer=True,has_offscreen_renderer=False,use_camera_obs=False,
)# reset the environment
env.reset()action = np.random.randn(env.robots[0].dof) # sample random action
obs, reward, done, info = env.step(action)
for i in obs:print(i)for i in range(1000):action = np.random.randn(env.robots[0].dof) # sample random actionobs, reward, done, info = env.step(action)  # take action in the environmentenv.render()  # render on display
env.close()

• 结果
  

• 如果最后没有用env.close()手动关闭环境的话，程序结束后会报错：
