Minecraft is one of the most popular video games in the world, with over 200 million copies sold and more than 130 million monthly active users. It is a sandbox game that allows players to create and explore infinite worlds made of blocks, where they can build, craft, fight, and survive.

But what if you could play Minecraft with an artificial intelligence (AI) agent that can understand your commands, perform complex tasks, and learn from internet videos? That’s the idea behind Voyager MineDojo, a new project that aims to create open-ended embodied agents with internet-scale knowledge.

What is Voyager MineDojo?

Voyager MineDojo is a framework for building AI agents to play Minecraft using natural language instructions. Nvidia and several academic institutions developed it, and it won an Outstanding Datasets and Benchmarks Paper Award at the 2023 NeurIPS conference.

The framework consists of two main components: MineCLIP and MineDojo. Miniclip is a custom transformer model associating video clips with specific in-game Minecraft activities. It is trained on 730,000 Minecraft YouTube videos, 7,000 scraped webpages from the Minecraft wiki, 340,000 Reddit posts, and 6.6 million Reddit comments describing Minecraft gameplay.

MineDojo is an AI agent that uses MineCLIP to execute actions from written prompts in Minecraft. It can perform open-ended tasks, such as finding a desert pyramid, building a nether portal, crafting diamond tools, or making a farm. It can also generalize learned actions and apply them to different behaviors in the game.

How does It work?

To use Voyager MineDojo, install Minecraft Java Edition on your computer and download the Voyager mod from its website https://voyager.minedojo.org/. The mod allows you to communicate with the AI agent using a chat interface in the game.

You can then type any command you want the agent to do, such as “build a house” or “mine some iron”. The agent will parse your command using MineCLIP and try to execute it in the game. It will also give you feedback on its progress and ask for clarification if needed.

The agent can also learn from reinforcement learning, which means it gets rewarded for achieving each step in a sequence of tasks. For example, if you tell it to craft a diamond pickaxe, it will get rewarded for collecting wood, stone, iron, and diamonds in order.

Why is Voyager MineDojo important?

Voyager MineDojo is important because it demonstrates the potential of using internet-scale data to train AI models that can perform diverse and complex tasks in realistic environments. It also shows how natural language can be an intuitive interface for interacting with AI agents.

Voyager MineDojo is a fun way to play Minecraft with an AI companion and a valuable tool for AI research and education. It can help researchers test new algorithms and methods for building generalist agents that adapt to different situations and goals. It can also help students learn about AI concepts and applications by experimenting with different commands and scenarios in the game.

What are some examples of Voyager MineDojo?

Here are some examples of what Voyager MineDojo can do in Minecraft:

• Build a house: The agent can build a simple house with a door, windows, roof, and floor.
• Find a desert pyramid: The agent can navigate through different biomes and locate a desert pyramid structure.
• Craft diamond tools: The agent can collect all the necessary materials and craft diamond tools such as a pickaxe, sword, axe, shovel, and hoe.
• Make a farm: The agent can plant seeds, water them, harvest crops, and store them in chests.
• Enter the nether: The agent can build a nether portal using obsidian blocks, flint, and steel, light it up, and enter it.

Conclusion

Voyager MineDojo is an innovative project that combines internet-scale data, natural language processing, computer vision, and reinforcement learning to create open-ended embodied agents that can play Minecraft using written prompts. It is a fun way to enjoy Minecraft with an AI partner and a powerful framework for AI research and education.
