📄 RESEARCH

PAPER 1: GRAPH-GUIDED SAFE DIFFUSER (G2SD)

Many diffusion planners enforce safety by deforming trajectories at inference time, which breaks kinematic feasibility. G2SD uses a high-level topological graph to guide the diffusion planner hierarchically, preserving feasibility while keeping trajectories collision-free - a cleaner separation of safety and kinematics than prior interleaved approaches.

PAPER 2: EFFICIENT REAL-WORLD ONLINE RL FOR ROBOT MANIPULATION

Online RL in the physical world avoids the sim-to-real gap but is normally too sample-hungry. This paper achieves practical sample efficiency via centralized training and critic decomposition - splitting value estimation into components - enabling continuous policy refinement through human-in-the-loop interaction without excessive real-world trials.

PAPER 3: LYAPUNOV-GUIDED EVOLUTIONARY OPTIMIZATION (LyEvO)

Sim-to-real transfer fails when simulation safety does not translate. LyEvO combines constrained evolutionary optimization with Lyapunov stability certificates, providing physics-grounded readiness assessments before real deployment and producing controllers that are demonstrably safer under distributional shift.

PAPER 4: WORLD ACTION MODEL ADAPTIVE EXECUTION (Rethink Before You Execute)

World Action Models generate action chunks and execute a fixed prefix before replanning, which is poorly matched to actual execution dynamics. This paper proposes adaptive execution horizons - executing more or fewer steps depending on predicted uncertainty - improving efficiency without changing the underlying WAM architecture.

PAPER 5: VERNATA - SELF-SUPERVISED LiDAR POINT REPRESENTATIONS

3D annotation for outdoor robot LiDAR is scarce and expensive. Vernata uses self-supervised learning to build strong LiDAR point representations from unlabeled scans, directly addressing the labeled-data bottleneck that limits deep learning on outdoor robot perception.
