Special Issue Information

Dear Colleagues,

The integration of robotic and autonomous systems across various industries, from transportation and manufacturing to healthcare and agriculture, has marked significant technological advancement. These systems are designed to undertake complex tasks autonomously by making decisions and executing actions in real time. However, the ever-present uncertainties inherent in dynamics, environmental conditions, and interactions with other agents pose significant challenges to the seamless functioning of these systems. Reliable and effective decision-making and control mechanisms in the face of uncertainties are crucial for the safety and efficiency of these systems. In light of these imperatives, this Special Issue endeavors to delve into the forefront of advancements in decision-making and control techniques tailored for robotic and autonomous systems operating within uncertain contexts.

This Special Issue cordially invites original research articles, comprehensive reviews, and illuminating case studies that revolve around the pivotal theme of decision-making and control for robotic and autonomous systems operating under uncertainties. The topics encompassed will encompass a wide spectrum, including but not limited to:

  1. Robust, adaptive, and data-driven control;
  2. Risk-aware decision-making under perceptual and/or dynamics uncertainties;
  3. Safe learning in robotics;
  4. Deep learning approaches for decision-making in uncertain environments;
  5. Sensor fusion and perception algorithms for reliable decision-making;
  6. Fault detection and diagnosis techniques;
  7. Human-robot interactions and collaboration in uncertain environments;
  8. Decision-making under resource constraints and limited information;
  9. Decision-making and control in real-world robotic and autonomous systems.

Addressing a collision-aware multi-robot mission planning problem, which involves task allocation and path-finding, poses a significant difficulty due to the necessity for real-time computational efficiency, scalability, and the ability to manage both static and dynamic obstacles and tasks within a complex environment. This paper introduces a parallel real-time algorithm aimed at overcoming these challenges. The proposed algorithm employs an approximation-based partitioning mechanism to partition the entire unassigned task set into several subsets. This approach decomposes the original problem into a series of single-robot mission planning problems. To validate the effectiveness of the proposed method, both numerical and hardware experiments are conducted, involving dynamic obstacles and tasks. Additionally, comparisons in terms of optimality and scalability against an existing method are provided, showcasing its superior performance across both metrics. Furthermore, a computational burden analysis is conducted to demonstrate the consistency of our method with the observations derived from these comparisons. Finally, the optimality gap between the proposed method and the global optima in small-size problems is demonstrated. Full article

Differential drive mobile robots, being widely used in several industrial and domestic applications, are increasingly demanding when concerning precision and satisfactory maneuverability. In the present paper, the problem of independently controlling the velocity and orientation angle of a differential drive mobile robot is investigated by developing an appropriate two stage nonlinear controller embedded on board and also by using the measurements of the speed and accelerator of the two wheels, as well as taking remote measurements of the orientation angle and its rate. The model of the system is presented in a nonlinear state space form that includes unknown additive terms arising from external disturbances and actuator faults. Based on the nonlinear model of the system, the respective I/O relation is derived, and a two-stage nonlinear measurable output feedback controller, analyzed into an internal and an external controller, is designed. The internal controller aims to produce a decoupled inner closed-loop system of linear form, regulating the linear velocity and angular velocity of the mobile robot independently. The internal controller is of the nonlinear PD type and uses real time measurements of the angular velocities of the active wheels of the vehicle, as well as the respective accelerations. The external controller aims toward the regulation of the orientation angle of the vehicle. It is of a linear, delayed PD feedback form, offering feedback from the remote measurements of the orientation angle and angular velocity of the vehicle, which are transmitted to the controller through a wireless network. Analytic formulae are derived for the parameters of the external controller to ensure the stability of the closed-loop system, even in the presence of the wireless transmission delays, as well as asymptotic command following for the orientation angle. To compensate for measurement noise, external disturbances, and actuator faults, a metaheuristic algorithm is proposed to evaluate the remaining free controller parameters. The performance of the proposed control scheme is evaluated through a series of computational experiments, demonstrating satisfactory behavior. Full article
