Development of a dynamic path for a toxic substances mapping mobile robot in industry environment
Some industries have critical areas (dangerous or hazardous) where the presence of a human must be reduced or avoided. In some cases, there are areas where humans should be replaced by robots. The present work uses a robot with differential drive to scan an environment with known and unknown obstacles, defined in 3D simulation. It is important that the robot be able to make the right decisions about its way without the need of an operator. A solution to this challenge will be presented in this paper. The control application and its communication module with a simulator or a real robot are proposed. The robot can perform the scan, passing through all the waypoints arranged in a grid. The results are presented, showcasing the robot’s capacity to perform a viable trajectory without human intervention.Project ”TEC4Growth - Pervasive Intelligence, Enhancers and Proofs of Concept with Industrial Impact/NORTE-01-0145-FEDER-000020” is financed by the North Portugal Regional Operational.

Rackham: An Interactive Robot-Guide
International audienceRackham is an interactive robot-guide that has been used in several places and exhibitions. This paper presents its design and reports on results that have been obtained after its deployment in a permanent exhibition. The project is conducted so as to incrementally enhance the robot functional and decisional capabilities based on the observation of the interaction between the public and the robot. Besides robustness and efficiency in the robot navigation abilities in a dynamic environment, our focus was to develop and test a methodology to integrate human-robot interaction abilities in a systematic way. We first present the robot and some of its key design issues. Then, we discuss a number of lessons that we have drawn from its use in interaction with the public and how that will serve to refine our design choices and to enhance robot efficiency and acceptability
GUARDIANS final report
Emergencies in industrial warehouses are a major concern for firefghters. The large dimensions together with the development of dense smoke that drastically reduces visibility, represent major challenges. The Guardians robot swarm is designed to assist fire fighters in searching a
large warehouse. In this report we discuss the technology developed for a swarm of robots searching and assisting fire fighters. We explain the swarming algorithms which provide the functionality by which the robots react to and follow humans while no communication is required. Next we
discuss the wireless communication system, which is a so-called mobile ad-hoc network. The communication network provides also one of the means to locate the robots and humans. Thus the robot swarm is able to locate itself and provide guidance information to the humans. Together with
the re ghters we explored how the robot swarm should feed information back to the human fire fighter. We have designed and experimented with interfaces for presenting swarm based information to human beings
Development of an autonomous mobile towing vehicle for logistic tasks
Frequently carrying high loads and performing repetitive
tasks compromises the ergonomics of individuals, a recurrent scenario
in hospital environments. In this paper, we design a logistic planner of
a fleet of autonomous mobile robots for the automation of transporting
trolleys around the hospital, which is independent of the space configuration,
and robust to loss of network and deadlocks. Our robotic solution
has an innovative gripping system capable of grasping and pulling nonmodified
standard trolleys just by coupling a plate. Robots are able to
navigate autonomously, to avoid obstacles assuring the safety of operators,
to identify and dock a trolley, to access charging stations and
elevators, and to communicate with the latter. An interface was built
allowing users to command the robots through a web server. It is shown
how the proposed methodology behaves in experiments conducted at the
Faculty of Engineering of the University of Porta and Braga's Hospital.This work is financed by the ERDF - European Regional
Development Fund through the Operational Programme for Competitiveness and Internationalisation-
COMPETE 2020 Programme, and by National Funds through the Portuguese
funding agency, FCT-Fundação para a Ciência e a Tecnologia, within project
