This article presents a key-scenario of H/R interaction for our tourguide robot. Given this scenario, three visual modalities, the robot deals with, have been outlined, namely the “search of visitors” attending the exhibition, the “proximal interaction” through the robot interface and the “guidance mission”. The paper focuses on the two last ones which involves face recognition and visual data ...

Classical ways for coordinate measuring devices are manual theodolites, photogrammetry-based systems, total stations and a recently-introduced device referred to as laser tracker systems. Basically, a laser tracker system is a more accurate and reliable 3D measurement tool that allows to increase and maintain accuracy as time goes by. Laser tracker systems deals with industry-based measuring pr...

Extended Abstract Robots need to track objects. We identify two kinds of tracking problems in which: (i) the tracker is static or does not actuate on the tracked object and (ii) the tracker actu-ates on the object. This thesis focuses on the latter problem. Tracking is performed by a robot executing specific tasks acting over the object being tracked, such as a Segway RMP soccer robot grabbing ...

In this paper, we describe a visual servoing system developed as a human-robot interface to drive a mobile robot toward any chosen target. An omni-directional camera is used to get the 360 degree of field of view, and an efficient SSD based tracking technique is developed to track the target. The use of the omnidirectional geometry eliminates many of the problems common in visual tracking and m...

We consider tasks where robots act on the target that is visually tracked, such as kicking a ball or pushing an object. We introduce a principled approach to incorporate models of the robot-object interaction into the tracking algorithm to effectively improve the performance of the tracker. We first present the integration of a single robot behavioral model with multiple actions into our dynami...

A visual tracking system is essential as a basis for visual servoing, autonomous navigation, path planning, robot-human interaction and other robotic functions. To execute various tasks in diverse and ever-changing environments, a mobile robot requires high levels of robustness, precision, environmental adaptability and real-time performance of the visual tracking system. In keeping with the ap...

We present a visual servoing system for an amphibious legged robot. That is, a monocular-vision based servoing mechanism that enables the robot to track and follow a target both underwater and on the ground. We used three different tracking algorithms to track and localize the target in the image, with color being the tracked feature. Tracking is performed based on the object’s color, color dis...

In order to create a social robot, able to interact with people in a natural way, one of the things it should be able to do is to follow a person around an area. This master’s research is aimed at enabling a Sony AIBO robot dog to watch people closely and follow them around the house. This is done using the visual data provided by the robot’s nose-mounted camera. By analysing the data with resp...

mobile robot navigation is one of the basic problems in robotics. in this paper, a new approachis proposed for autonomous mobile robot navigation in an unknown environment. the proposedapproach is based on learning virtual parallel paths that propel the mobile robot toward the trackusing a multi-layer, feed-forward neural network. for training, a human operator navigates themobile robot in some...

BACKGROUND In image-guided robotic interventions, an error component is related to the positioning error of the manipulator. Therefore, measuring the kinematic error is required during robot development. However, no specialized measurement device exists for this task. This study explores the possibility of using optical tracking for robot measurement. METHODS A CNC machine is used to position...
