—We present a novel technique that robustly segments free-space for robot navigation purposes. In particular, we are interested in a reactive visual navigation, in which the rapid and accurate detection of free space where the robot can navigate is crucial. Contrary to existing methods that use multiple cameras in different configurations, we use a(More)
The field of Robotics is ever growing at the same time as posing enormous challenges. Numerous works has been done in biologically inspired robotics emulating models, systems and elements of nature for the purpose of solving traditional robotics problems. Chromatic behaviours are abundant in nature across a variety of living species to achieve camouflage,(More)
— We present a visual based approach for reactive autonomous navigation of an underwater vehicle. In particular, we are interested in the exploration and continuous monitoring of coral reefs in order to diagnose disease or physical damage. An autonomous underwater vehicle needs to decide in real time the best route while avoiding collisions with fragile(More)
This paper describes a multi-robot system purposed to guide a group of people that encompasses a strategy to conduct and crowd persons by a team of three mobile robots. It includes: a methodology to localise (track) the members of the group; a suitable multi-robot system architecture design; and a motion planner that synchronises and controls (guides) the(More)
Throughout this article we present a methodology to localize multiple people in a group by a multi-robot system (MRS). The aim of the MRS is to conduct people through hallways in indoors as a guided-tour service task. However, further than guidance process, we detail a method for humans' localization by sharing distributed sensor data arising from the team(More)
