The Dung Beetle Optimization (DBO) algorithm is a powerful metaheuristic algorithm that is
widely used for optimization problems. However, the DBO algorithm has limitations in …

Navigating between the different floors of a multistory building is a task that requires walking
up or down stairs or taking an elevator or lift. This work proposes a procedure to take a …

Fast recognition of elevator buttons is a key step for service robots to ride elevators
automatically. Although there are some studies in this field, none of them can achieve real …

Autonomous elevator operation is considered a promising solution for mobile navigation in
office buildings. As a fundamental function, elevator button recognition remains unsolved …

In recent years, the demand for delivery services has increased by applying robot

Three-dimensional (3D) reconstruction technology is the key technology to establish and
express the objective world by using computer, and it is widely used in real 3D, automatic …

In this work, we propose an approach for the autonomous navigation of mobile robots using
fusion the of sensor data by a Double Deep Q-Network with collision avoidance by detecting …

Mobile service robot multi-floor navigation is a challenging issue for in indoor robot
navigation, especially when moving between floors, entering and leaving elevator. So, in …

A wheeled mobile manipulator to navigate between floors needs to recognize the
information of the elevator's buttons and operate them. This paper proposes an autonomous …

Wheeled mobile robots in multiple stories buildings have to use elevator to access arbitrary
floor of the building. To do so, the control system must be able to detect and access elevator …
