Lévy Flight Foraging Hypothesis-based Autonomous Memoryless Search Under Sparse Rewards
Christos Papachristos, Kostas Alexis
Autonomous robots are commonly tasked with the problem of area exploration and search for certain targets or artifacts of interest to be tracked. Traditionally, the problem formula…
Optical Flow Based Background Subtraction with a Moving Camera: Application to Autonomous Driving
Sotirios Diamantas, Kostas Alexis
In this research we present a novel algorithm for background subtraction using a moving camera. Our algorithm is based purely on visual information obtained from a camera mounted o…
Design and Control of an Aerial Manipulator for Contact-based Inspection
Varun Nayak, Christos Papachristos, Kostas Alexis
Manipulator dynamics, external forces and moments raise issues in stability and efficient control during aerial manipulation. Additionally, multirotor Micro Aerial Vehicles impose…
Visual-Inertial Odometry-enhanced Geometrically Stable ICP for Mapping Applications using Aerial Robots
Tung Dang, Shehryar Khattak, Christos Papachristos +1
This paper presents a visual-inertial odometry-enhanced geometrically stable Iterative Closest Point (ICP) algorithm for accurate mapping using aerial robots. The proposed method e…
