Isaac Lab
A GPU-accelerated robot learning platform developed by NVIDIA, supporting large-scale parallel simulation and designed for robotics reinforcement learning research and development. It is widely used as a robot RL training infrastructure in both industry and academia.

在Isaac Lab中观察到训练崩溃时关节力矩停滞在-1到1 Nm之间，几乎没有探索行为
MuJoCo uses a soft-constraint-based contact model that approximates penetration through penalty terms, while Isaac Lab is based on the GPU-parallel PhysX engine optimized for large-scale parallel simulation.
The developer encountered contact/friction issues in Isaac Lab, unable to find realistic and reasonable foot-ground friction regardless of tuning—small parameters caused slipping while large parameters made it feel as if the feet were glued to the ground.
Isaac Lab can run thousands of simulation environments in parallel on a single GPU, compressing training that would otherwise take days down to hours.
Isaac Lab's core advantage lies in keeping physics simulation, rendering, and neural network training entirely within GPU VRAM, avoiding the data-transfer bottleneck between CPU and GPU.
Isaac Lab (formerly Isaac Orbit) is a robot learning framework released by NVIDIA, built on the Omniverse platform and using the PhysX 5 engine at its core.
Through PhysX 5, Isaac Lab can compute thousands of simulation environment instances in parallel on a single GPU, achieving massively parallel simulation, and compiles the simulation-inference loop into a static computation graph via CUDA Graph technology to eliminate synchronization overhead.
For undergraduate graduation projects, it is recommended to first complete core algorithm validation with PyBullet, and attempt migration to Isaac Lab for comparative experiments only if time permits.
For an undergraduate thesis, choosing Isaac Lab may extend the environment setup phase to 4–5 weeks, severely compressing time for subsequent algorithm development; PyBullet allows teams to enter the algorithm development phase more quickly.
Isaac Lab's PhysX 5 engine can compute thousands of simulation environments in parallel on the GPU, achieving massively parallel simulation, which has a tremendous acceleration effect on RL training that requires large amounts of sampling.
