Intelligent robotics and neuroscience

Summary
                  The paper is an editorial introducing the linkage today between robotics and neural science, going through a little bit of history of robotics.
Autonomous robotics is cited as the most complete paradigm of Artificial Intelligence, since it is characterized by perception, planning and action.
Mobile Robotics, today more an more under the attention of researches, is not only dealing with complex program and non-analytic human knowledge, it is also managing to uncertainties and complexity and error measurement, making it incorporated also with typical problems more strictly related to robotics, in addition to dependence on technology development.
In the sixties there has been a great improvement in Autonomous Robots research, some principles of robotics where applied during a time in which a “General Problem Solver” was researched and the result at the time was “Shakey”, a mobile robot that used memory and logical reasoning to solve problems and navigate in its environment. “Shakey” at the time was a great leap forward, but it was still lacking in completely being autonomous, in fact is was controlled by an off-board computer and it wasn’t able to operate in high uncertain area. The seventies are depicted by the author as a “technological bottle-neck” for robotics, only in the mid-eighties there has been a come back, mainly in the concept laying behind autonomous robotics, since the idea of “modular computation” was introduced, with the aim of avoiding the problem of huge knowledge databases trying to solve infinite problem cases, but introducing modular programs capable of being called when required.
The idea that sensors and effectors are coupled with perceptions and actions brought in the concept of “conduct based” paradigm, denoting similarity between robots and ethology studies.
Here is were the origins of cybernetics are (“Embodiment of Mind” – McCulloh, Kilmer) and it developed in being a science covering robotics, psychology and biology, making it in the end a bioinspired robotics.
The XXI century is denoting the challenge of both scientific disciplines: Autonomous Robotics and Neuroscience and there is where we can see the attempt of controlling robotics using biological neuroblatoma and EEG applied in the field of brain-computer interface.
Studies on robotics team working through social rules is another way of applying ethology studies in robotics and studies are done also in observations in how humans select routes in crowded environments.
The author reports that we are still far from obtaining results, but that this is the direction of this coming period.
Key Concepts
Autonomous Robotics, Artificial Intelligence.
Key Results
 The paper results interesting under the aspect of which are the key points that have been necessary to achieve the real concept of autonomous robotics. As stated, we had to wait for the mid eighties before entering the concept of modularity in programming languages and this helped a lot in further steps, making it possible to improve control systems and communication systems.
Interesting is the parallelism between ethology and robotics, which is remarked also by inventions and studies done in this direction, making robots as animals.
It would be interesting to understand whether this concept is actually applied under the idea that the robot is an external entity or if it can be viewed as a tool, not as it used to be thought till the eighties, but as biological tool, part of the human being, as it has been shown in studies regarding EEG applications in robotic control, specially in the case of assisting people with sever disabilities.
