Soon, ‘robobees’ that mimic bees’ behaviour

Washington, Sep 13 (ANI): A Northeastern University neurobiologist is collaborating with Harvard University researchers to develop micro flying robots that will emulate the bees’ brain, body and collective behaviour.

Biology professor Joseph Ayers would create robots, called the robobees, which would mimic the communal feeding behaviour of bee colonies.

The project will draw on the knowledge of computer scientists, engineers, and biologists to construct an electronic nervous system, a supervisory architecture and a high-energy source to power the innovative robots.

“This project will integrate the efforts and expertise of a diverse team of investigators to create a system that far transcends the sum of its parts. We expect substantial advances in basic science at the intersection of these seemingly disparate disciplines to result from this effort,” said Ayers.

Inspired by the biology of the bee and the insect’s colonial behaviour, the project aims to advance miniature robotics and the design of compact high-energy power sources.

The project would also spur innovations in ultra-low-power computing and electronic “smart” sensors that mediate biomimetic control.

In addition, it would refine coordination algorithms to manage multiple, independent machines.

Ayers is widely known for his work in biomimetics- the science of adapting the control systems found in nature to inform design of engineered systems to solve real-world problems-including the development of RoboLobster and RoboLamprey.

The autonomous, biomimetic underwater robotic models emulate the operations of the animals’ nervous systems using an electronic controller based on nonlinear, moving models of neurons and synapses.

“Animals have evolved to occupy every environmental niche where we would hope to operate robots, save outer space. They provide proven solutions to problems that confound even the most sophisticated robots, and our challenge is to capture these performance advantages in engineered devices,” said Ayers. (ANI)

‘Super-recognizers’ who never forget a face do exist

Washington, May 20 (ANI): Harvard University researchers have bolstered the claim that “super-recognizers”-people with extraordinary face recognition ability who never forget someone they met in the past-do exist.

Richard Russell, a postdoctoral researcher in the Department of Psychology at Harvard, has found in a study that skill in facial recognition may vary widely among humans.

Studies conducted in the past have shown that about 2 per cent of the population suffers from “face-blindness”, or prosopagnosia, a condition characterized by great difficulty in recognizing faces.

This is the first time that a study has shown that others excel in face recognition, indicating that the trait could be on a spectrum, with prosopagnosics on the low end and super-recognizers at the high end.

The researchers involved standardized face recognition tests in their study, and found the super-recognizers to score far higher than any of the normal control subjects.

“There has been a default assumption that there is either normal face recognition, or there is disordered face recognition. This suggests that’s not the case, that there is actually a very wide range of ability. It suggests a different model-a different way of thinking about face recognition ability, and possibly even other aspects of perception, in terms of a spectrum of abilities, rather than there being normal and disordered ability,” says Russell.

The researchers say that the super-recognizers reported being able to recognize other people far more often than they are recognized.

Russell says that it is for this reason that they often compensate by pretending not to recognize someone they met in passing, so as to avoid appearing to attribute undue importance to a fleeting encounter.

“Super-recognizers have these extreme stories of recognizing people. They recognize a person who was shopping in the same store with them two months ago, for example, even if they didn’t speak to the person. It doesn’t have to be a significant interaction; they really stand out in terms of their ability to remember the people who were actually less significant,” says Russell.

Given that one woman in the study was able to prove that she had identified another woman on the street who served as a waitress five years earlier in a different city, the researchers came to the conclusion that super-recognizers are able to recognize another person despite significant changes in appearance, such as aging or a different hair color.

The researchers say that studying differences in people’s ability to recognize faces may be important for assessing eyewitness testimony, or for interviewing for some jobs, such as security or those checking identification.

A research paper on the study has been published in Psychonomic Bulletin and Review. (ANI)
