A legged_gym based framework for training legged robots in Genesis, IsaacGym and IsaacSim.
-
Totally based on legged_gym
This framework keeps most apis and conventions consistent with legged_gym, providing good readability and better control over training pipeline.
-
Integration of multiple simulators
We support training in either of three simulators: IsaacGym, Genesis and IsaacSim.
Quick tips for choosing among three simulators:
- Faster training but worse rendering -> IsaacGym
- Both training speed and support for fluid, soft materials -> Genesis
- More realistic rendering at the cost of training speed -> IsaacSim.
