Mobility analysis is crucial to fast, safe, and autonomous operation of planetary Wheeled Mobile Robots (WMRs). This paper reviews implemented odometry techniques on currently designed WMRs surveys methods for improving their mobility traversability. The are categorized based the employed approaches ranging from signal-based model-based estimation terramechanics-based, machine learning, global ...

We present a control framework for achieving encirclement of a 3D target using a multi-robot system. Three variations of a basic control strategy are proposed for different versions of the encirclement problem, and their effectiveness is formally established. An extension ensuring maintenance of a safe inter-robot distance is also discussed. The proposed framework is fully decentralized and onl...

This paper presents a new motion planning algorithm for wheeled mobile robots in presence of known static obstacles, especially well-suited for high velocity situations. It takes into account several conditions traditionally attached to smooth path planning, i.e. paths with continuous derivative and upper-bounded curvature. It makes use of a global path planner which exploits polynomial G curve...

The majority of navigation algorithms for mobile robots assume that the robots possess enough computational or memory resources to carry out the necessary calculations. Especially small and lightweight devices, however, are resource-constrained and have only restricted capabilities. In this paper, we present a reinforcement learning approach for mobile robots that considers the imposed constrai...

We tackle the problem of forming and deploying groups of robots in a dynamic task allocation scenario. In our approach, wheeled robots carry out tasks and flying robots coordinate the formation and subsequent deployment of groups of wheeled robots. Our recruitment system is based on simple probabilistic rules inspired by the aggregation behaviour of cockroaches under shelters. The system succes...

The goal of this research was to develop a fuzzy obstacle avoidance system for an autonomous mobile robot using IR detection sensors. This paper presents implemented control architecture for behavior-based mobile robot. The mobile robot is able to interact with an unknown environment using a reactive strategy determined by sensory information. Current research in robotics aims to build autonomo...
