In this paper, an evolutionary approach to solve the mobile robot path planning problem is proposed. The proposed approach combines the artificial bee colony algorithm as a local search procedure and the evolutionary programming algorithm to refine the feasible path found by a set of local procedures. The proposed method is compared to a classical(More)
In this paper, we show a comparative review of Connected Component Labeling (CCL) methods, focused in two-pass variants, including their elements and implementation issues. We analyze the main elements used by these CCL algorithms and their importance for the performance of the methods using them. We present some experiments using a complex image set and(More)
This article describes the localization function integrated in a landmark-based navigation system. It relies on the use of planar landmarks (typically, posters) to localize the robot. It is based on two periodic processes running at different frequencies. One of them performs the poster tracking (based on the partial Hausdorff distance) and the active(More)
Cutting and packing problems arise in many fields and situations. The general case is expressed as follows [7]: Input Given a set of n items with dimensions d1, . . . , dn and a set of m bins with capacities c1, . . . , cn. Problem description How can all the items be packed? Esentially bin packing is an optimization problem known to be NP-Hard [1]. Most of(More)
This paper describes how to integrate tracking functions on a mobile robot. Tracking is required during autonomous robot navigation in different situations: landmark tracking to guarantee real-time robot localization, target tracking for a sensor based motion or obstacle tracking to control an obstacle avoidance procedure. These objects -landmarks, targets,(More)
