| this paper presents the rst path planner taking into account both non-holonomic and uncertainty constraints. The case of a car-like robot subject to cumulative and unbounded connguration uncertainty related to bounded control and sensing errors is considered. Assuming the existence of landmarks allowing the robot to relocalize itself in particular places, we present an algorithm that computes paths that are both feasible and robust. In other words, they respect the non-holonomic constraints of a car-like robot and the robot is assured to reach its goal by following them as long as its control and sensing errors remain within bounded sets.Inrets c Praxit ele programme on individual urban public transports 1994-1997], and the Inco-Copernicus ERB-IC15-CT96-0702 project \Multi-agent robot systems for industrial applications in the transport domain" 1997-1999].

مسیریابی حرکت روبات‌های ماشین‌واره با روش پیشروی سریع

The Robot Motion Planning (RMP) problem deals with finding a collision-free start-to-goal path for a robot navigating among workspace obstacles. Such a problem is also encountered in path planning of intelligent vehicles and Automatic Guided Vehicles (AGVs). In terms of kinematic constraints, the RMP problem can be categorized into two groups of Holonomic and Nonholonomic problems. In the first...

Solving Path Following Problem for Car-Like Robot in the Presence of Sliding Effect via LMI Formulation

One of the main problems of car-like robot is robust path following in the presence of sliding effect. To tackle this problem, a robust mix H2/H∞ static state feedback control method is selected. This method is the well-known linear robust controller which is robust against external disturbance as well as model uncertainty. In this paper, the path following problem is formulated as linear matri...

LQG-MP: Optimized Path Planning for Robots with Motion Uncertainty and Imperfect State Information

This paper presents LQG-MP (linear-quadratic Gaussian motion planner), a new approach to robot motion planning that takes into account the sensors and the controller that will be used during execution of the robot’s path. LQGMP is based on the linear-quadratic controller with Gaussian models of uncertainty, and explicitly characterizes in advance (i.e., before execution) the apriori probability...

Path Based Mapping Technique for Robots

The purpose of this paper is to explore a new way of autonomous mapping. Current systems using perception techniques like LAZER or SONAR use probabilistic methods and have a drawback of allowing considerable uncertainty in the mapping process. Our approach is to break down the environment, specifically indoor, into reachable areas and objects, separated by boundaries, and identifying their shap...
