A researcher from the Universidad de Granada has created a system which makes robots ‘see’ people and interact with them

13.12.2007
Although there have been great improvements in the field of robotics in the last fifty years, much work remains in order to introduce androids into our daily life.

Rafael Muñoz Salinas, a researcher from de Department of Computer Science and Artificial Intelligence of the University of Granada, is the author of a doctoral thesis which represents a major improvement in the interaction between robots and human beings. His study, entitled ‘Soft-Computing and Computer Vision Techniques Applied to Autonomous robot navigation and Human-robot Interaction’, has managed to develop a series of perception-motor skills which notably improve the natural interaction between robots and human users.

“The aim of our study is to make robots the most accessible tools in our homes and work places", explains Rafael Muñoz, “and for this reason, it is necessary to develop techniques which help to increase the level of autonomy of mobile robots”. For this, it is fundamental to minimize human intervention, in order to introduce robots into our lives.

The work performed at the UGR has made it possible to combine the use of vision techniques, as well as flexible computation applied to navigation and perception problems, in order to give robots better movement skills.

“Our second objective is related to the development of perception-motor skills which give mobile robots basic skills of natural interaction”, states Rafael Muñoz. “Because, although robots have to be able to act autonomously, “their purpose is always to serve human beings”.

Interaction
The study carried out at the UGR has made it possible for a robot to detect humans and interact with them rather than consider them mere obstacles. “The most important aspect is that this communication has to be natural. The use of screens, keyboards or mice in order to communicate can be a limitation when we try to introduce robots into our daily life. It is better to use communication mechanisms more similar to the ones human beings use, such as visual communication, voice, gestures, etc.”, explains the researcher.

The improvements achieved in this field have contributed to the first attempts to use mobile robots in a wide rage of applications in our daily life, such as personal robots, robot pets, guide robots in museums and personal robot assistants for the disabled or elderly.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
