  1. 1. Energy efficient multi-robot coordination

    Author : Oskar Wigström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; scheduling; optimization; hybrid systems; multi-robot systems; energy minimization;

    Abstract : When multiple systems work in the same physical environment, it is important to ensure that no collisions occur. This thesis is focused on the centralized offline coordination of such collaborating systems, with the condition that the spatial path each system travels along is known before hand. READ MORE

  2. 2. Coordination, Consensus and Communication in Multi-robot Control Systems

    Author : Alberto Speranzon; Karl Henrik Johansson; George J. Pappas; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-robot Coordination; Intelligent Control; Control under Communication Constraints; Automatic control; Reglerteknik;

    Abstract : Analysis, design and implementation of cooperative control strategies for multi-robot systems under communication constraints is the topic of this thesis. Motivated by a rapidly growing number of applications with networked robots and other vehicles, fundamental limits on the achievable collaborative behavior are studied for large teams of autonomous agents.

  3. 3. Formations and Obstacle Avoidance in Mobile Robot Control

    Author : Petter Ögren; KTH; []
    Keywords : Mobile Robots; Robot Control; Obstacle Avoidance; Multi-robot system; Formation Control; Navigation Function; Lyapunov Function; Model Predictive Control; Receding Horizon Control; Gradient Climbing; Gradient Estimation.;

    Abstract : This thesis consists of four independent papers concerningthe control of mobile robots in the context of obstacleavoidance and formation keeping. The first paper describes a new theoreticallyv erifiableapproach to obstacle avoidance. READ MORE

  4. 4. Preattentive gaze control for robot vision

    Author : Carl-Johan Westelius; Linköpings universitet; []
    Keywords : Robot vision; Resolution pyramids; Phase-based disparity estimation; Focus of attention; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : A framework for a hierarchical approach to gaze control of a robot vision system is presented, and a implementation on a simulated robot is described. The robot is equipped with a heterogeneous sampled imaging system, a fovea, resembling the varying resolution in a human retina. READ MORE

  5. 5. Optimal Coordination of Flexible Manufacturing Systems, with Automatic Generation of Collision- and Dealock-Free Working Schedule

    Author : Avenir Kobetski; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Visibility Graphs; Scheduling; A*; Mixed Integer Linear Programming; Discrete Event Systems; Velocity Balancing.; Robot Coordination; Supervisory Control Theory; Deterministic Finite Automata; Flexible Manufacturing;

    Abstract : The ever more rapidly changing markets pose high demands on the modern industry, often making it necessary to have varied and frequently updated product portfolios. As a consequence, modern industrial systems need to be easily adaptable to different kinds of products, which makes the use of flexible manufacturing systems (FMS) increasingly popular. READ MORE
