In this paper, we consider a multi-robot cooperative control problem via a robust consensus tracking algorithm. The main objective of this paper is to develop and implement a multi-robot formation control testbed and use it to verify the effectiveness of a cooperative control algorithm developed in our recent work. In the robust consensus tracking algorithm, an observer is developed to identify the...
The cluster space state representation for multirobot systems provides a simple means of specifying and monitoring the geometry and motion characteristics of a cluster of mobile robots. In previous work, this approach has been experimentally verified and validated for controlling the motion of planar mobile multi-robot systems ranging from land rovers to autonomous boats. In this paper we present...
This paper presents a motion control algorithm for a multiple mobile autonomous agents using the concept of a rigid and persistent formation with a Leader-Follower structure. Initially, a triangular formation was started for three agents and subsequently Henneberg Sequence [Tolga, et al; 2005] is applied to extend for multi-agent system. A decentralized control for each agent considering the shortest...
This article presents a design of a four-wheeled omnidirectional mobile robot for RoboCup middle size league. The mobile robot was built for the 5dpo-2000 robotic soccer team from the Department of Electrical and Computer Engineering at the University of Porto, Portugal. The robot's architecture and communication structure are presented. A nonlinear modeling and a motion analysis based on the dynamics,...
The problem of multi-robot cooperative localization based on relative bearings is researched in this paper. Relative bearings of different robots are fused with motions to improve the localization accuracy of robots. We analyse the situations about relative positions of the robots and their motion trajectories. Some relative positions and motion trajectories of the robots easily lead to not-converged...
Communication-aware motion control allows mobile networked robots to increase the average communication throughput. We exploit that in a multipath fading channel, robots can measure the SNR and adapt their motion to spend slightly more time at positions where the channel is good. Two new such cross-layer strategies are analyzed and evaluated: periodic stopping, where the stop duration is a function...
This paper reports an autonomous cooperative navigation system for robot formations in realistic scenarios. The formation movement control is based on a virtual structure composed by spring-dampers elements, which allows the formation to comply with the environment shape. A different navigation strategy is applied to the leader of the formation and to the rest of robots of the team. The leader plans...
This paper addresses the problem of planning paths for multiple mobile robots moving in the same environments. We try to decrease the computational complexity of path planning, which is one of the fundamental limiting characteristics in the existing work of path planning. Unlike many other approaches to this problem, we assume the robots are restricted by the limited-communication range such that...
In this paper we present a layered architecture for multirobot motion coordination. The purpose is to control and coordinate autonomous mobile robot with generic shapes and kinematics in a priori known environment. It is a centralized framework, where a leader robot (or a supervisor) plans the motion of all the robots and makes them moving synchronously. The architecture is layered and modularized,...
