Special Issue Information

Dear Colleagues,

An essential factor in the development of robotics, autonomous vehicles, and unmanned aerial vehicles (UAVs) is the determination of safe and intelligent navigation in complex and dynamic environments, known as path planning or motion planning. From the initial position to the desired goal, efficient and effective path-planning algorithms are crucial in enabling a sequence of actions or motions to be carried out while avoiding obstacles or constraints in the environment. Certain factors must be considered in path planning, e.g., the minimal distance travelled, evasion of hindrance, consideration of dynamic obstacles, or optimization of other performance metrics. Path planning and autonomous navigation have attracted considerable interest and attention in recent years owing to several factors:

  • Rapid developments in robotics, sensor technologies, and computing power have created new possibilities for autonomous navigation.
  • The rise of autonomous vehicles, including self-driving cars, drones, and others, has led to a strong demand for efficient and safe path-planning algorithms.
  • Industrial automation and robotics: robots are increasingly employed for logistics, warehouse automation, and manufacturing tasks.
  • Applications in unstructured environments: path planning and autonomous navigation are crucial when human intervention is restricted or impractical.

The present high interest in path planning and autonomous navigation can be attributed to the desire to cultivate intelligent, efficient, and safe systems that can operate independently in varied surroundings. It is predicted that further high-quality research and technological improvements in this field will significantly affect industries, transportation, and various aspects of our everyday lives. This Special Issue aims to collect innovative contributions on this subject. Specifically, contributions may address the following aspects of “Path Planning and Autonomous Navigation”:

  1. Dynamic and motion planning for mobile robots and UAVSs
  2. SLAM
  3. Energy-efficient path planning
  4. Real-time and adaptive path planning
  5. Autonomous navigation systems using reinforcement learning
  6. Deep reinforcement learning
  7. Localization and mapping algorithms
  8. Multi-agent systems and swarm robotics
  9. Navigation in GPS-denied environments
  10. Efficient exploration and mapping

"Advances in Path Planning and Autonomous Navigation" aims to provide a leading resource for researchers and practitioners in the field, and we invite authors to contribute their expertise and research findings to this Special Issue.

This article presents an innovative method for planning and tracking the trajectory in the image plane for the visual control of a quadrotor. The community of researchers working on 2D control widely recognizes this challenge as complex, because a trajectory defined in image space can lead to unpredictable movements of the robot in Cartesian space. While researchers have addressed this problem for mobile robots, quadrotors continue to face significant challenges. To tackle this issue, the adopted approach involves considering the separation of altitude control from the other variables, thus reducing the workspace. Furthermore, the movements of the quadrotor (pitch, roll, and yaw) are interdependent. Consequently, the connection between the inputs and outputs cannot be reversed. The task complexity becomes significant. To address this issue, we propose the following scenario: When the quadrotor is equipped with a downward-facing camera, flying at high altitude is sensible to spot a target. However, to minimize disturbances and conserve energy, the quadrotor needs to descend in altitude. This can result in the target being lost. The solution to this problem is a new methodology based on the principle of differential flatness, allowing the separation of altitude control from the other variables. The system first detects the target at high altitude, then plots a trajectory in the image coordinate system between the acquired image and the desired image. It is crucial to emphasize that this step is performed offline, ensuring that the image processing time does not affect the control frequency. Through the proposed trajectory planning, complying with the constraints of differential flatness, the quadrotor can follow the imposed dynamics. To ensure the tracking of the target while following the generated trajectory, the proposed control law takes the form of an Image Based Visual Servoing (IBVS) scheme. We validated this method using the RVCTOOLS environment in MATLAB. The DJI Phantom 1 quadrotor served as a testbed to evaluate, under real conditions, the effectiveness of the proposed control law. We specifically designed an electronic card to transfer calculated commands to the DJI Phantom 1 control joystick via Bluetooth. This card integrates a PIC18F2520 microcontroller, a DAC8564 digital-to-analogue converter, and an RN42 Bluetooth module. The experimental results demonstrate the effectiveness of this method, ensuring the precise tracking of the target as well as the accurate tracking of the path generated in the image coordinate system.

The technological advancements in sensory systems and robotics over the past decade have facilitated the innovation of centralized systems for optimizing resource utilization and monitoring efficiency in inspection applications. This paper presents a novel system designed for gas concentration sensing in environments by implementing a modular artificial nose (emulating the inhalation and exhalation process) equipped with a strategically designed air capture centralization system based on computational fluid dynamics analysis (CFD). The system incorporates three gas identification sensors distributed within the artificial nose, and their information is processed in real-time through embedded systems. The artificial nose is hardware–software integrated with a quadruped robot capable of traversing the environment to collect samples, maximizing coverage area through its mobility and locomotion capabilities. This integration provides a comprehensive perspective on gas distribution in a specific area, enabling the efficient detection of substances in the surrounding environment. The robotic platform employs a graphical interface for real-time gas concentration data map visualization. System integration is achieved using the Robot Operating System (ROS), leveraging its modularity and flexibility advantages. This innovative robotic approach offers a promising solution for enhanced environmental inspection and monitoring applications. Full article
