Lazy Evaluation of Multi-Grasp Goals Guided by Motion Planning in Pick-and-Place Object Manipulation

F. Duman, E. S. Tok, J. D. Hernández

This work integrates grasp planning and motion planning to jointly solve pick-and-place tasks in cluttered environments, where treating them separately often yields grasp poses the robot cannot reach. Grasp affordances are represented as continuous workspace goal regions that approximate the goal regions defined in configuration space, turning the task into an extended start-to-goal motion planning problem solved with a sampling-based tree planner. Simulated and real-world Franka Emika experiments show improved grasping accuracy and higher manipulation success rates.

Learning-based Object Center Adjustment for 3D Reconstruction using an Eye-in-Hand Robotic Manipulator

J. J. Patiño, F. Duman, V. Romero-Cano, Y. Lai, J. D. Hernández

This paper presents a robotic object reconstruction approach using an eye-in-hand fixed-base manipulator under non-optimal reachability conditions. A partial reconstruction from initially reachable views guides an ML-based strategy to determine object displacements that maximize reachable viewpoints. Simulation and real-world experiments demonstrate improved reconstruction quality, achieving greater surface coverage and area compared with systems without object displacement adjustment.

Learning-Informed Motion Planning Toward Workspace Goal Regions for Object Manipulation in Constrained Environments

F. Duman, J. J. Patiño, V. Romero-Cano, J. D. Hernández

This work treats pick-and-place manipulation as start-to-goal-region motion planning, where valid grasps and placements define multiple workspace goals. It introduces a transformer-guided sampling-based tree planner that uses start and goal configurations plus visual observations to improve planning in constrained shelf environments. Simulated and real-world Franka Emika tests show faster planning, higher success rates, and effective transfer from simulation to robot execution.

Social Robot Navigation Under Kinodynamic Constraints Using Learning-Informed Sampling for Indoor Environments

S. Silva, V. Romero-Cano, J. D. Hernández

Presents a social robot navigation framework for socially acceptable, kinodynamically feasible motion in dynamic indoor spaces. The approach combines world representation, multilayered path planning, and path-following control. A CNN-driven informed sampling strategy improves planner performance for online navigation. Benchmarks against state-of-the-art methods and real-world Reachy robot tests demonstrate the framework’s feasibility.

Supervisory Control via AR for Teleoperation under Communication Delays: An In-Space Assembly Use Case

I. M. Stavropoulos, A. Kucukyilmaz, C. Martinez, D. J. Finnegan, J. D. Hernández

Presents an AR-supported supervisory control system for in-space assembly under communication delays. Operators define goals in a 3D AR interface, while behaviour trees handle execution and recovery. In a user study, the approach reduced completion time, effort, and workload compared with shared control under 0s and 2s latency.
