Welcome to the world of manipulation skills in robotics! The ManiSkill Benchmark is designed for researchers exploring real-world object manipulation from 3D visual inputs. This blog will guide you through installing and utilizing the benchmark to help you train and visualize your robotic policies.

Understanding the ManiSkill Benchmark

The ManiSkill Benchmark, short for SAPIEN Manipulation Skill Benchmark, is a platform that provides a diverse array of tasks related to manipulating 3D objects. Imagine trying to teach a robot to open a cabinet or push a chair—this benchmark creates a testing ground for such tasks, offering a rich variety of 3D object shapes and complexities. By harnessing a state-of-the-art full-physics simulator, researchers can explore the intricacies of robotic manipulation in a controlled environment.

Getting Started with ManiSkill

System Requirements

• Ubuntu 18.04 or 20.04 (16.04 is not supported)
• Nvidia GPU with at least 6GB memory
• Nvidia Graphics Driver 460+ (lower versions may work but are untested)

Installation Steps

1. Clone the ManiSkill repository:

git clone https://github.com/haosulab/ManiSkill.git
cd ManiSkill

2. Install dependencies from environment.yml:

conda env create -f environment.yml
conda activate mani_skill

3. Install the ManiSkill package:

pip install -e .

Running a Basic Example

Now that you have installed ManiSkill, it’s time to run an environment. The analogy for this process is like taking your new robot for its first trial run at a miniature obstacle course. Here’s a simple code snippet to get you started:

import gym
import mani_skill.env

env = gym.make('OpenCabinetDoor-v0')  # Choose an environment
env.set_env_mode(obs_mode='state', reward_type='sparse')  # Configure observation and reward types

for level_idx in range(5): 
    obs = env.reset(level=level_idx)
    for i_step in range(100000):
        action = env.action_space.sample()  # Take a random action
        obs, reward, done, info = env.step(action) 
        if done: 
            break

env.close()

In this code, you’re guiding the robot through a series of actions to open a cabinet door, making it learn through trial and error, just like a human trying to learn how to operate a new tool!

Viewer Tutorial

To visualize the interactions, use the env.render(human) function to open the SAPIEN viewer. This is akin to watching a live stage performance where you can move around and observe the actions up close. However, remember not to reset a level while interacting with an object, or you’ll crash the program!

Troubleshooting

If you encounter any issues during installation or while running your environment, consider the following troubleshooting tips:

• Ensure your GPU drivers are up to date and compatible with your operating system.
• Check the repository for updates and ensure you’ve installed all dependencies correctly.
• Refer to the FAQ section on the ManiSkill GitHub page.
• If visualizations do not work in the Docker environment, ensure Docker has access to your graphics card and your local x-server.
