Competitive Complexity of Mobile Robot On Line Motion Planning Problems
This paper is concerned with on-line problems where a mobile robot of size D has to achieve a task in an unknown planar environment whose geometry is... -
Algorithmic Foundation of the Clockwork Orange Robot Soccer Team
The Dutch robot soccer team Clockwork Orange is a research project of the Delft University of Technology and the University of Amsterdam. In this... -
Gap Navigation Trees: Minimal Representation for Visibility-based Tasks
In this paper we present our advances in a data structure, the Gap Navigation Tree (GNT), useful for solving different visibility-based robotic tasks... -
Randomized Algorithms for Minimum Distance Localization
We address the problem of minimum distance localization in environments that may contain self-similarities. A mobile robot is placed at an unknown... -
Multi-Point Contact Models for Dynamic Self-Righting of a Hexapod
In this paper, we report on the design of a model-based controller that can achieve dynamical self-righting of a hexapod robot. Extending on our... -
Stealth Tracking of an Unpredictable Target among Obstacles
This papers introduces the stealth tracking problem, in which a robot, equipped with visual sensors, tries to track a moving target among obstacles... -
Incremental Grid Sampling Strategies in Robotics
We present algorithms for generating deterministic sample sequences using incremental grid-based sampling. Our algorithms are designed to generate... -
Networked Robots: Ten Years of Experiments
As a feasibility study in 1994, we built a system that allows a robot manipulator to be teleoperated by the public via the Internet. Access control... -
Topological Map** with Sensing-Limited Robots
Most mobile robot map** and exploration research makes use of longrange, powerful sensors such as laser range.nders to create maps. In this paper... -
Probik: Protein Backbone Motion by Inverse Kinematics
To investigate the parameters of the protein design problem that we are exploring in collaboration with biochemists, we developed a tool that uses... -
6 Structural Properties of Discrete and Continuous Linear Time-Varying Systems: A Unified Approach
The aim of this chapter is the study of structural properties of linear systems. Systems with time-varying coefficients are considered, both in the... -
5 Algebraic Analysis of Control Systems Defined by Partial Differential Equations
The present chapter contains the material taught within the module P2 of FAP 2004. The purpose of this intensive course is first to provide an... -
1 Nonlinear Adaptive Stabilization via System Immersion: Control Design and Applications
This chapter presents a review of a recently developed methodology for the (adaptive) stabilization of nonlinear systems via state and output... -
1 Introduction to Nonlinear Optimal Control
The maximum principle is presented in the weak and general forms. The standard proofs are detailed, and the connection with the shooting method for... -
6 Stability, Told by Its Developers
Lyapunov stability theory is probably the most useful qualitative method to study the behaviour of dynamical systems; it benefits from at least 75... -
4 Stability Analysis of Time-delay Systems: A Lyapunov Approach
This chapter is devoted to the stability problem of time-delay systems using time-domain approach. Some basic concepts of time-delay systems are... -
5 Controllability of Partial Differential Equations
In this section, we recall some basic elements of semigroup theory (see [25]). In particular, all the arguments of the results mentioned below can be... -
Motion Planning for Domestic Robot Assistants
Service robots serve and assist human beings sharing a common work space. Collision-free motion paths have to be generated in short times for a... -
1 Multi-modal Robot Interfaces
The goal of effective interaction between user and robot assistant makes it essential to provide a number of broadly utilizable and potentially... -
Safety Improvement by Fault Diagnosis and Fault Recovery for the Perceptual System of Mobile Robots
This paper present an approach to safe navigation of autonomous mobile systems within partially known or unknown dynamic environments. In this...
