UnverifiedMuJoCo, whose full name is Multi-Joint dynamics with Contact, is a high-fidelity physics simulation engine that has become the de facto standard in the field of robot reinforcement learning.65% similarUnverifiedMuJoCo uses a generalized coordinate system rather than a Cartesian coordinate system to describe multi-body dynamics, achieving extremely high computational efficiency when handling high-degree-of-freedom joint systems.64% similarUnverifiedRoxie focuses on the vertical domain of MuJoCo continuous control rather than being a large, all-encompassing general-purpose RL library.59% similarUnverified主流仿真平台如MuJoCo和Isaac Sim均采用简化的刚体接触模型，以牺牲部分物理精度换取实时仿真速度59% similarUnverifiedMuJoCo 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.58% similar
