Learning Dexterity

OpenAI is a non-profit AI research company, discovering and enacting the path to safe artificial general intelligence. They’ve trained a human-like robot hand to manipulate physical objects with unprecedented dexterity.

Their system, called Dactyl, is trained entirely in simulation and transfers its knowledge to reality, adapting to real-world physics.

Dactyl learns from scratch using the same general-purpose reinforcement learning algorithm and code as OpenAI Five. Their results show that it’s possible to train agents in simulation and have them solve real-world tasks, without physically-accurate modeling of the world.
