A new concept of a solar cell powering with integrated Global Positioning System (GPS) for microrobots is proposed. The main idea is to use a projector to transfer energy and to provide global positioning information to the robots that are equipped with multi-segment solar cells on their top. First tests with a 3000 ANSI lumens beamer projecting a white(More)
The inspection of low diameter pipes is a subject of great complexity due to the small operation environment in which the tasks must be developed. Besides, the construction of microrobots for specific pipe inspection is too expensive. In this article, a modular multiconfigurable architecture is presented. The fact of being modular and multiconfigurable(More)
This paper presents a novel tablet based end-user interface for industrial robot programming (called Hammer). This application makes easier to program tasks for industrial robots like polishing, milling or grinding. It is based on the Scratch programming language, but specifically design and created for Android OS. It is a visual programming concept that(More)
Heterogeneous modular robots are a subject of great complexity due to the control problems derived from the different characteristics of each of the modules and the interactions amongst them. In this article, a control structure based on behaviors for robots composed of different drive units and other purpose modules is presented. This article mainly(More)
This paper presents the architecture used to develop a micro-robot for narrow pipes inspection. Both the electromechanical design and the control scheme will be described. In pipe environments it is very useful to have a method to retrieve information of the state of the inside part of the pipes in order to detect damages, breaks and holes. Due to the(More)
A 2 degrees of freedom module for pipe inspection modular micro-robots based on servomotors is presented in this article. A mechanical and electrical description of the module is also given, including the kinematics and the close control loop design to detect obstacles (walls). The main configurations in which it can be used are described as well:(More)
This paper describes our ongoing effort to build an empathizing and adaptive storyteller system. The system under development aims to utilize emotional expressions generated from an avatar or a humanoid robot in addition to the listener’s responses which are monitored in real time, in order to deliver a story in an effective manner. We conducted a pilot(More)
This article presents a new control architecture designed for heterogeneous modular, multi-configurable, chained micro-robots. This architecture attempts to fill the gap that exists in heterogeneous modular robotics research, in which little work has been conducted compared to that in homogeneous modular robotics studies. The architecture proposes a(More)
In order to create effective storytelling agents three fundamental questions must be answered: first, is a physically embodied agent preferable to a virtual agent or a voice-only narration? Second, does a human voice have an advantage over a synthesised voice? Third, how should the emotional trajectory of the different characters in a story be related to a(More)
This paper presents a communication interface between supervisory low-cost mobile robots and domestic Wireless Sensor Network (WSN) based on the Zig Bee protocol from different manufacturers. The communication interface allows control and communication with other network devices using the same protocol. The robot can receive information from sensor devices(More)
