UniLab: A Heterogeneous Architecture for Robot RL Beyond GPU-Dominant Paradigms
Yufei Jia, Zhanxiang Cao, Mingrui Yu +48
Simulation-based RL for contemporary robot control is increasingly organized around GPU-resident simulation: physics, rollout collection, and learning are placed on a single GPU-ce…
FGGS-LiDAR: Ultra-Fast, GPU-Accelerated Simulation from General 3DGS Models to LiDAR
Junzhe Wu, Yufei Jia, Yiyi Yan +6
While 3D Gaussian Splatting (3DGS) has emerged as a strong representation for photorealistic rendering, its vast ecosystem of assets remains difficult to use for high-performance L…
DISCOVERSE: Efficient Robot Simulation in Complex High-Fidelity Environments
Yufei Jia, Guangyu Wang, Yuhang Dong +17
We present the first unified, modular, open-source 3DGS-based simulation framework for Real2Sim2Real robot learning. It features a holistic Real2Sim pipeline that synthesizes hyper…
Omni-Perception: Omnidirectional Collision Avoidance for Legged Locomotion in Dynamic Environments
Zifan Wang, Teli Ma, Yufei Jia +5
Agile locomotion in complex 3D environments requires robust spatial awareness to safely avoid diverse obstacles such as aerial clutter, uneven terrain, and dynamic agents. Depth-ba…
Preference Aligned Diffusion Planner for Quadrupedal Locomotion Control
Xinyi Yuan, Zhiwei Shang, Zifan Wang +7
Diffusion models demonstrate superior performance in capturing complex distributions from large-scale datasets, providing a promising solution for quadrupedal locomotion control. H…
Rewarded Region Replay (R3) for Policy Learning with Discrete Action Space
Bangzheng Li, Ningshan Ma, Zifan Wang
We introduce a new on-policy algorithm called Rewarded Region Replay (R3), which significantly improves on PPO in solving environments with discrete action spaces. R3 improves samp…
Arm-Constrained Curriculum Learning for Loco-Manipulation of the Wheel-Legged Robot
Zifan Wang, Yufei Jia, Lu Shi +6
Incorporating a robotic manipulator into a wheel-legged robot enhances its agility and expands its potential for practical applications. However, the presence of potential instabil…
