[1] TOP: Trajectory Optimization via Parallel Optimization towards Constant Time Complexity

Jiajun Yu, Nanhe Chen, Guodong Liu, Chao Xu, Fei Gao, and Yanjun Cao

Proposed an ADMM-based parallel trajectory optimization framework that decomposes trajectories into independent sub-problems, reducing per-iteration time complexity to O(1). Achieved >10× speedup over serial SOTA on 100-segment trajectories; GPU deployment enables millisecond-level optimization for 1000-segment trajectories.

[2] Learning Safety-enhanced Navigation with Integrated Model Information

Nanhe Chen, Jiajun Yu, Mengke Zhang, Pengxiang Zhou, Chao Xu, Fei Gao, and Yanjun Cao

Proposed an end-to-end visual navigation framework integrating differentiable physics engine with safety-constrained policy optimization. Leveraged PALM for near-KKT convergence in a single loop. Achieved zero-shot sim-to-real transfer across differential-drive, tracked, and quadruped platforms with zero collision rate in dense environments.

[3] ATRS: Adaptive Trajectory Re-splitting via a Shared Neural Policy for Parallel Optimization

Jiajun Yu, Guodong Liu, Chao Xu, Fei Gao, and Yanjun Cao

Proposed embedding a shared deep RL agent into the ADMM optimization loop to dynamically restructure trajectory segments, eliminating the optimization bottleneck. Modeled adaptive splitting as a MASP-MDP with a shared Actor-Critic architecture, generalizing across arbitrary segment counts. Achieved 26% fewer iterations and 19.1% less computation time versus baselines; real quadrotor traversing unknown forests in 35 ms.

[4] Whole-body Planning for Any-Shape Robot directly in Point Cloud

Guodong Liu, Jiajun Yu, Chao Xu, Fei Gao, and Yanjun Cao

Proposed a dual-layer framework for whole-body trajectory optimization of arbitrary-shape robots directly in raw point clouds. Leveraged convex decomposition for differentiable signed-distance constraints with ADMM-based parallel solving. Full GPU pipeline completes in 19.86 ms in narrow mixed environments; real quadrotor with LiDAR navigates unknown environments in real time.

[5] CoNiPA: Cooperative Non-inertial Control Framework with LSTM-Enhanced Predictive Awareness

Mingxuan Zhang, Jiajun Yu, Baozhe Zhang, Chao Xu, Fei Gao, and Yanjun Cao

Proposed an active perception-aware control framework for GPS-denied air-ground cooperation. Unified UAV trajectory and gimbal orientation optimization under non-inertial dynamics via MPC. LSTM-based time-varying IMU prediction compensates for model mismatch. Achieved >98% target visibility and 20 cm tracking accuracy in aggressive maneuvers across simulation and real-world experiments.
