ROBOT LEARNING / RESEARCH PORTFOLIO

Predict.
Remember. Act.

I am Hetian Guo, a Ph.D. student in Artificial Intelligence at Jilin University. My research focuses on VLA policy learning, predictive world models, visuo-tactile manipulation, and whole-body motion generation, with experiments on bipedal humanoids, wheeled platforms, and bimanual setups.

PLaW-VLA

PLaW-VLA: Predictive Latent World Modeling for Vision-Language-Action Policies

Co-first author

Predicts future states in a pretrained visual latent space rather than reconstructing pixels and couples state prediction with action generation. Average success reaches 97.4% on LIBERO and 72.7% on LIBERO-Plus, with long-horizon, fine-grained, and deformable-object manipulation tested on Astribot S1.

BeliefVLA

BeliefVLA: Implicit Belief-State Driven Vision-Language-Action Models for Robust Manipulation

Second author

Infers an implicit belief state from observation history to add temporal memory and dynamics priors to VLA control; evaluated bimanual tasks and visual perturbations on Realman, ARX R5, and AgileX PIPER.

SeMoCo

SeMoCo: A Semantic-First Motion Codec for Motion Language Modeling

Co-first author

A semantic VQ and kinematic-residual RVQ form hierarchical motion tokens; a dual-axis generator models temporal semantics and refines motion within each token. The work also builds the unified-skeleton Ω-MotionVerse dataset, with generated motions replayed on G1 through Sonic.

TacDyn-WAM

TacDyn-WAM: Learning Implicit Tactile Dynamics in a Heterogeneous Visuo-Tactile World Action Model

Collaborative research

Learns a dynamics-aware tactile target space to predict contact evolution at multiple horizons and couples visual/tactile experts for action generation; achieved 81.5% average success on UniVTAC with real-robot validation.
