HANDLE - Developmental Pathway towards Autonomy and
Dexterity in Robot In-Hand Manipulation
 The
HANDLE project aims at understanding how humans perform the manipulation of
objects in order to replicate grasping and skilled in-hand movements with an
anthropomorphic artificial hand, and thereby move robot grippers from
current best practice towards more autonomous, natural and effective
articulated hands. This project will focus on technological developments
and, in addition, research fundamental multidisciplinary research aspects in
order to endow the proposed robotic hand with advanced perception
capabilities, high level feedback control and elements of intelligence that
allow recognition of objects and context, reasoning about actions and a high
degree of recovery from failure during the execution of dexterous tasks. HANDLE:
Developmental Pathway Towards Autonomy and Dexterity in Robot In-Hand
Manipulation is an European project coordinated by the university Pierre and
Marie Curie of Paris and include a consortium formed by nine partners from
six EU countries: France, UK, Spain, Portugal, Sweden and Germany.
The field of robotics is undergoing a major revolution as it is increasingly
being applied to general purposes outside the production line: for health,
rehabilitation and professional services, in domestic and leisure
environments, as well as hazardous environments. There, one keystone for
robots to carry out accurate and intelligent tasks, with and for people, is
their ability both to handle autonomously all sorts of objects and to use
human tools. However, today's robots are unable to achieve dexterous and
fine manipulation, especially when this requires in-hand manipulation. They
are far from being able to understand and reason about their environments,
their goals and their own capabilities, to learn skills and improve their
performance by what they have been taught and their own experience, to
interact with their environments with the efficiency of humans.
The HANDLE project aims at understanding how humans perform the manipulation
of objects in order to replicate grasping and skilled in-hand movements with
an anthropomorphic artificial hand, and thereby move robot grippers from
current best practice towards more autonomous, natural and effective
articulated hands. The project implies not only focusing on technological
developments but also working with fundamental multidisciplinary research
aspects in order to endow the robotic hand system with advanced perception
capabilities, high level feedback control and elements of intelligence that
allow recognition of objects and context, reasoning about actions and a high
degree of recovery from failure during the execution of dexterous tasks.
Integrating findings from disciplines such as neuroscience, developmental
psychology, cognitive science, robotics, multimodal perception and machine
learning, the method we will develop is based on an original blend of
learning and predicting behaviours from imitation and "babbling" to allow
the robot to be capable of responding to gaps in its knowledge.

PROMETHEUS - Prediction and interpretation of human
behaviour based on probabilistic structures and heterogeneous sensors
 The
project intends to establish a link between fundamental sensing tasks and
automated cognition processes that concern the understanding a short-term
prediction of human behaviour as well as complex human interaction. The
analysis of human behaviour is unrestricted environments, including
localization and tracking of multiple people and recognition of their
activities, currently constitutes a topic of intensive research in the
signal processing and computer vision communities. This research is driven
by different important applications, including unattended surveillance and
intelligent space monitoring.

Multisensor Fusion and Multirobot Systems for 3D Reconstruction: DIVA – Dirigível Instrumentado para Vigilância Aérea
 DIVA is the Portuguese acronym for "Dirigível
Instrumentado para Vigilância Aérea".
The project involves a team of researchers from IDMEC/IST, from ISR/Coimbra
from the University of Minho.
The global goal of the project is the design of a solution based on a
small size airship as an aerial stable platform for a semi-autonomous
monitoring and surveillance mission.
This is a project in the area of aerial robotics, an area which has
justified a growing interest in recent times, with very different
application objectives, namely in the civilian domain, for monitoring of
roads, detection of forest fires, inspection of power lines. Among the
advantages of the airship solution, we may cite its natural stability, low
operational costs, reduced pollution, and the ability to move at very low
airspeeds or even hover.
The long period of absence of airships resulted in a lower knowledge of
their potential usage and flight characteristics. A first objective of the
project is to permit a better description of its flight characteristics and
propose alternative solutions based on the most recent control techniques,
resulting in an aerial platform for semi-autonomous monitoring, with
adequate mobility and stability characteristics. The project involves both
the area of aerodynamics and the area of modelling and control, along with
the area of systems integration, including the relevant aspects of mission
safety.
A second objective, already mentioned as an application mission, is to
explore the mobility of the airship to develop a surveillance system based
on images, to monitor and recognize the motion of objects, allowing the
inspection of ground areas with the reference of digital maps drawn from the
airship cameras, from a low/medium altitude. The following list is a set
of architecture specifications and concepts, separated in airship and ground
control categories:
AIRSHIP
- Intelligent semi autonomous mode operation (on board PC will be
PC104+).
- Radio control receiver - An human pilot with a radio control unit
(as in model airplanes) may take control of the airship at any time, for
safety reasons .
- Actuators and flight control:
- 1. Internal combustion engines
- 2. Propellers with 90º vectorization
- 3. Helium valve for emergency landing
- Localization and navigation:
- 1. GPS
- 2. Visual landmarks (digital images from firewire camera)
- 3. Inertial and magnetic sensors
- 4. Pressure sensor
- 5. Wind sensor
- Mission specific sensors:
- 1. High resolution zoom camera
- 2. Environmental sensors
GROUND CONTROL
- Mission planning (with a Ground Station PC)
- Ground station sensors
- 1.DGPS
- 2.meteorological station: wind, pressure,
temperature, humidity, etc..
- Wireless Ethernet link between airship and ground
station
- Full monitoring and logging of airship telemetry
data
- Ground station can send mission related commands
- allows minimumCORBA (TAO) as a middleware

IRPS - Intelligent Robotic Porter System
IRPS (Intelligent Robotic Porter System) is a Specific
Target Research Project (STREP) co-sponsored by the European Commission
under the Information Society Technology (IST) priority under the 6th
Framework Programmeand and has currently 8 partners which can be found here.
The project addresses the strategic objective of "Advanced Robotics".
As robots are becoming more popular, they should be able to further
integrate information and communication technologies with physical
interaction capabilities. The main purpose of the IRPS project is to develop
an accurate 3D sensing system to be integrated as a modular component for
robotics platforms, enabling fast dense mapping of large areas populated
with sparse objects. This will make them useful in a new variety of services
in the professional and private sector.
The measurements principles developed by IAI-LAHAV (a division of the Israel
Aircraft Industries) for 3D measurement provide an opportunity to introduce,
in robotics, a highly accurate measurement system, named LIMS. This system
is based on an innovative concept of 3D real time measurements of position
in presence of sparse objects and vibrations, and will allow mapping of
large areas, in real time, at the speed of 5m/s.
The proposed LIMS will thus enable robotics applications with safe, robust
and dependable capabilities, allowing operation in human enironments and
co-operating with people. In particular, the project will develop and
demonstrate the LIMS on an high demanding application as an Intelligent
Robotic Porter System to help port and guide the public in airport areas.

Project conducted under the Thematic Priority: Information Society
Technologies - Sub-topic: Cognitive Systems - of the 6th Framework
Program of the European Commission.
Main Goal and Objectives
By taking up inspiration from the brains of mammals, including
humans, the BACS project will investigate and apply Bayesian models
and approaches in order to develop artificial cognitive systems that
can carry out complex tasks in real-world environments. |
Goals
The Bayesian approach will be used to model different levels of brain
function within a coherent framework. The Bayesian models will be validated
and adapted as necessary according to neurophysiological data and
psychophysical experiments. The Bayesian approach will also be used to
develop artificial cognitive systems concerned with autonomous navigation,
multimodal perception and reconstruction of the environment, semantic facial
motion tracking, human body motion recognition and behaviour analysis.
 Challenges
- The development of feasible probabilistic models of complex
cognitive processes for perception and action/decision;
- The successful application of such models on artificial platforms to
carry out complex tasks in real –world environments.
Contributions
Multimodal Perception: a moving observer is presented with a non-static 3D
scene containing several moving objects, probably (but not necessarily!)
generating some kind of sound because of a working motor, moving mechanical
parts or movement friction alone: how does this observer perceive his own
motion (egomotion), the 3D structure of all objects in the scene and the 3D
trajectory and velocity of moving objects (independent motion)?
Gesture Recognition: when a moving observer is addressed by a human
interlocutor, how does this observer interpret the latter’s gestures given
the uncertainty intrinsic to their execution and even to their
interpretation?
