Isaac Lab: A GPU-Accelerated Simulation Framework for Multi-Modal Robot Learning
NVIDIA's Isaac Lab report describes a GPU-accelerated simulation framework and benchmarks a simulated Digit rough-terrain locomotion environment.
Why it matters
We present Isaac Lab, the natural successor to Isaac Gym, which extends the paradigm of GPU-native robotics simulation into the era of large-scale multi-modal learning. Isaac Lab combines high-fidelity GPU parallel physics, photorealistic rendering, and a modular, composable architecture for designing environments and training robot policies.

Evidence notes
- Isaac Lab includes Digit among 11 simulated robot morphologies in its locomotion environment suite.
- The Digit rough-terrain benchmark uses a 1.6-by-1.2-metre RayCaster height scanner at 0.1-metre resolution and models closed-loop kinematic chains.
- The report benchmarks perceptive locomotion throughput across L40, RTX Pro 6000 and GeForce 5090 GPUs; the Digit results are simulation-only.
Company context
US robotics company focused on humanoid systems for logistics and warehouse automation. Digit is designed for real-world material handling tasks in structured environments.
