“…In recent years, mobile robots have been increasingly used in various applications of logistics and supply chain management [1][2][3] . Several examples have been demonstrated to optimize and improve industrial processes, drawing attention from both academy and industry [4][5][6] . Many companies are trying to speed up their production processes by applying just-in-time (JIT) strategies with the aim of increasing efficiency and reducing waste by receiving goods only as needed in the production process by reducing inventory costs 7 .…”

The paper deals with the design and testing of a robot for industrial applications featuring omnidirectionality thanks to the use of mecanum wheels. While this architecture provides remarkable manoeuvrability in narrow or cluttered spaces, it has some drawbacks that limit its widespread deployment in practice, especially for heavy-duty and long-duration tasks. As an example, the variability in the mecanum wheel rolling radius leads to undesired dynamic ill-effects, such as slippage and vibrations that affect the accuracy of pose estimation and tracking control systems. Drawing on the modeling of the kinematic and dynamic behaviour of the robot, these effects have been tackled within an adaptive estimation framework that adjusts the robot control system based on the properties of the surface being traversed. The proposed approach has been validated in experimental tests using a physical prototype operating in real industrial settings.

“…Complete equations of motion of the OMR which take into account the control torques applied to the wheel axes are examined in detail in [12,26]. In a number of other papers, e. g., in [22,23] and [27][28][29][30], an analysis has been made of the dynamics of the motion of the OMR, but only for specific wheel modifications and their specific arrangements, in particular, taking into account the rotation of rollers. However, there has been no estimate of the reaction force with emphasis on ensuring the constraint (2.1) (no-slip constraint on the wheels).…”

In this paper we present a study of the dynamics of a mobile robot with omnidirectional wheels taking into account the reaction forces acting from the plane. The dynamical equations are obtained in the form of Newton – Euler equations. In the course of the study, we formulate structural restrictions on the position and orientation of the omnidirectional wheels and their rollers taking into account the possibility of implementing the omnidirectional motion. We obtain the dependence of reaction forces acting on the wheel from the supporting surface on the parameters defining the trajectory of motion: linear and angular velocities and accelerations, and the curvature of the trajectory of motion. A striking feature of the system considered is that the results obtained can be formulated in terms of elementary geometry.

“…One of the challenges in modeling a slip control system is selecting the method of activation action. Currently, in automotive safety systems, regulators using fuzzy logic are commonly used and utilized [54][55][56][57][58]. A very promising way of modeling involves the use of artificial intelligence.…”

The article explored the potential for enhancing the off-road mobility of unmanned ground vehicles (UGV) equipped with a hydrostatic drive system. The analysis showed that effectively overcoming rough or soft terrain demands a slip limitation. In the UGVs with hydrostatic drives, flow dividers are used for this purpose. Unfortunately, they have certain drawbacks, such as reduced efficiency due to pressure losses. In order to minimize this phenomenon, an external braking system was used as a new slip control system. Therefore, simulation studies were carried out to assess the new slip control system while overcoming terrain obstacles due to the reduction of energy consumption and improving the mobility of the UGV.
