The Workshop of Physical Agents intends to be a forum for information and experience exchange in different areas regarding the concept of embodied agents, especially applied to the control and coordination of autonomous system: robots, mobile robots, industrial processes or…

Autonomous navigation is one of the most essential capabilities of autonomous robots. In order to navigate autonomously, robots need to detect obstacles. While many approaches achieve good results tackling this problem with lidar sensor devices, vision based approaches are cheaper…

Several works deal with 3D data in SLAM problem but many of them are focused on short scale maps. In this paper, we propose a method that can be used for computing the 6DoF trajectory performed by a robot from…

This paper describes the utilization of software design patterns and plan-based mission specification in the definition of AUVs missions. Within this approach, a mission is described in terms of a set of task-oriented plans in order to simplify mission definition…

This paper reviews the state of the art in coordinated multi-robot exploration and proposes a new exploration objective based on a practical scenery, reducing the difference of waiting time among different regions of a workspace, which has not been still…

In this article we describe the ethological inspired architecture we have developed and how it has been used to implement a humanoid goalkeeper according to the regulations of the two-legged Standard Platform League of the RoboCup Federation. We present relevant…

RoboCup provides a common research framework where a wide range of problems closely related to robotics and artificial intelligence must be addressed. The main focus of the RoboCup activities is competitive soccer. Thus, the visual identification of players and play-field…

This paper describes a novel approach for affine invariant region detection and description. At the detection stage, a hierarchical clustering mechanism is employed to group image pixels into regions. This process is based on the Bounded Irregular Pyramid (BIP) and…

When mining vehicle operators take risks, there is a increased probability of an accident that can cause injuries, fatalities and large financial costs to the mine operators. It can be assumed that the operators do not intentially take unnecessarily high…

This paper presents a probabilistic framework for unmarked roads estimation using radar sensors. The algorithm models the sensor likelihood function as a Gaussian mixture model. This sensor likelihood is used in a Bayesian approach to estimate the road edges probability…
