Selected Work

Recent research and engineering, from legged locomotion to field and industrial robotics.

2020–2025

Legged locomotion

Laelaps II: deep RL for quadruped locomotion

Trotting controllers for the Laelaps II quadruped that combine deep reinforcement learning with toe-level trajectory planning, tested in Gazebo on slopes up to 15°. A companion study compared DDPG, PPO and SAC; later work added a Cost of Transport reward for energy-efficient trotting in MuJoCo.

Second Prize Award — CLAWAR 2020

Agricultural robotics

Vinymap: vineyard inspection and 3D reconstruction

A vineyard inspection framework for a robot with three stereo cameras, combining autonomous navigation, high-fidelity 3D reconstruction and canopy growth assessment, tested in NTUA’s synthetic vineyard. Its multi-camera visual SLAM uses AprilTag loop closure and stays robust when one camera’s view is largely blocked.

2022–2024

Robotic harvesting

Robotic mushroom harvesting for existing farms

A low-cost gantry robot for existing mushroom-farm shelves: a 360° scanning RGB-D camera, YOLOv5 detection and model-fitting pose estimation, plus visual servoing, align a gripper with each mushroom’s angle of attack. Tested with 3D-printed mushrooms on real soil, within the EU-funded SoftGrip project.

Best Paper Award Finalist — AIM 2023

2023–2026

Navigation & inspection

Autonomous navigation, inspection and UAV swarms

Autonomous navigation and inspection: a local ESDF map that scales with vehicle speed for real-time replanning without GPS, collision-free UAV swarm coverage for disaster response, the ENORASI robot for extra-high-voltage substations, and in-pipe visual-inertial odometry that sprays its own fluorescent landmarks, eliminating tracking failures.

2025

Industrial AI

WEEE battery sorting and automotive quality control

Two AI-guided robotic systems: dual-energy X-ray imaging with YOLO and U-Net models that flag battery-containing e-waste for a Delta robot to pick off a moving conveyor, and a two-cobot cell detecting surface and thread defects on aluminum die-cast automotive parts in real time.

2019–2025

Gait analysis

Markerless gait analysis with computer vision

Low-cost alternatives to marker-based motion capture for gait analysis: OpenPose limb measurement, deep-learning 3D human mesh reconstruction from multiple RGB cameras with simulation-guided camera placement, and a minimal 2D human model estimating joint angles, torques and ground reaction forces from a stereo camera.
