End-to-End GPU accelerated

Physics simulation in Isaac Gym runs on the GPU, storing results in PyTorch GPU tensors

Thousand of Environments

Using the Isaac Gym tensor-based APIs, observations and rewards can be calculated on the GPU in PyTorch, enabling thousands of environments to run in parallel on a single workstation




Features

The core functionality of Isaac Gym will be made available as part of the NVIDIA Omniverse Platform and Isaac Sim robotics simulator in the future. Until then we are making this preview available to facilitate the work of researchers and academics who want to explore the potential of GPU-based reinforcement learning.

Isaac Gym features include:

  • Support for importing URDF and MJCF files
  • GPU accelerated tensor API for evaluating environment state and applying actions
  • Support for a variety of environment sensors – position, velocity, force, torque, etc
  • Runtime domain randomization of physics parameters
  • Jacobian / inverse kinematics support




Samples

A variety of examples and GPU accelerated training environments are also included:
